QSFP28 Optical Transceiver — Up to 2 km reach for 100G FEC-enabled systems

www.lumentum.com 2

The Lumentum 100G QSFP28 CWDM4 Optical Transceiver is a full duplex, photonic-

integrated optic transceiver that provides a high-speed link at aggregated data rate of

103.13 Gbps over 2 km of single-mode ber with a maximum link budget of 8 dB when

maximum transmitter and dispersion penalty (TDP) of 3 dB is presented. Operation at

103.125 Gbps requires the host system to enable Reed-Solomon Forward Error Correction

(RS-FEC) compliant with IEEE Std 802.3bj clause 91. For CWDM4 applications the RS-FEC

sublayer shall implement RS(528,514). This ensures post FEC bit error ratio (BER) of better

than 1x10-12with pre-FEC optical link BER of 5x10-5.

The Lumentum 100G QSFP28 CWDM4 Optical Transceiver

integrates transmit and receive path in one module. On the

transmit side, four lanes of serial data are recovered by a

programmable continuous time linear equalizer (CTLE), retimed

and passed to four laser drivers, which control four lasers with

center wavelengths of 1271 nm, 1291 nm, 1311 nm and 1331

nm. The optical signals are then multiplexed into a single-mode

ber through an industry standard LC connector. On the receive

side, four lanes of optical data streams are optically de-

multiplexed by an integrated optical demultiplexer. Each data

stream is recovered by a PIN photodetector transimpedance

amplier, retimed and passed to a CAUI-4 compliant output

driver.

This module features a hot-pluggable electrical interface, low

power consumption and 2-wire I2C management interface.

Transmitter

The transmitter path converts four lanes of serial NRZ electrical

data from line rate of 25.78 Gbps to a standard compliant optical

signal. Each signal path, accepts a 100  differential 100 mV

peak-to-peak to 900 mV peak-to-peak electrical signal on TDxn

and TDxp pins. Inside the module, each differential pair of electric

signals is input to an equalizer and then to a CDR (clock- data

recovery) chip. The recovered and retimed signals are then

passed to a laser driver which transforms the small swing voltage

to an output modulation that drives an un-cooled EML laser. The

laser drivers control four EMLs with center wavelengths of 1271

nm, 1291 nm, 1311 nm and 1331 nm, respectively. The optical

signals from the four lasers are optically multiplexed and coupled

to single-mode optical ber through an industry standard LC

optical connector. The optical signals are engineered to meet the

CWDM4 MSA specications.

Receiver

The receiver takes incoming combined four lanes of DC balanced

CWDM NRZ optical data from line rate of 25.78 Gbps through an

industry standard LC optical connector. The four incoming

wavelengths are separated by an optical demultiplexer into four

separated channels. Each output is coupled to a PIN

photodetector. The electrical currents from each PIN

photodetector are converted to a voltage in a high-gain

transimpedance amplier. The electrical output is recovered and

retimed by the CDR chip. The four lanes of reshaped electrical

signals are output on the RDxp and RDxn pins as a 100 

differential CAUI-4 chip-to-module signals.

Low-Speed Signaling

The Lumentum 100G QSFP28 CWDM4 Optical Transceiver has

several low-speed interface connections including a 2-wire serial

interface (SCL and SDA). These connections include; Low Power

Mode (LPMode), Module Select (ModSelL), Interrupt (IntL), Module

Present (ModPrsL) and Reset (ResetL) as shown in Figure 1.

ModSelL: The ModSelL is an input pin. When held low by the

host, the module responds to 2-wire serial communication

commands. The ModSelL allows the use of multiple QSFP28

modules on a single 2-wire interface bus. When the ModSelL is

“High”, the module does not respond to or acknowledge any

2-wire interface communication from the host.

In order to avoid conflicts, the host system shall not attempt

2-wire interface communications within the ModSelL de-assert

time after any QSFP28 module is deselected. Similarly the host

must wait for at least the ModSelL assert period of time before

communicating with a newly selected module. The assertion and

de-assertion periods of different modules may overlap as long as

the above timing requirements are met.

ResetL: The ResetL pin is pulled up to Vcc inside the QSFP28

module. A low level on the ResetL pin for longer than the

minimum pulse length (t_Reset_init) initiates a complete module

reset, returning all user module settings to their default state.

Module Reset Assert Time (t_init) starts upon the rising edge

after the low level on the ResetL pin is released. During the

execution of a reset (t_init) the host shall disregard all status bits

until the module indicates a completion of the reset interrupt. The

module indicates this by posting an IntL signal with the Data_

Not_Ready bit negated. Note that on power up (including hot

insertion) the module will post this completion of reset interrupt

without requiring a reset.

LPMode: : The LPMode pin is pulled up to Vcc inside the QSFP28

module. This function is affected by the LPMode pin and the

combination of the Power_over-ride and Power_set software

control bits (Address A0h, byte 93, bits 0,1).

The module has two modes: a low power mode and a high power

mode. The high power mode operates in one of the four power

classes.

QSFP28 Optical Transceiver — Up to 2 km reach for 100G FEC-enabled systems

www.lumentum.com 4

When the module is in a low power mode it has a maximum power

consumption of 1.5 W. This protects hosts that are not capable of

cooling higher power modules, should such modules be accidentally

inserted.

The module’s 2-wire serial interface and all laser safety functions are

fully operational in this low power mode. The module still supports

the completion of reset interrupt in this low power mode.

The Extended Identifier bits (Page 00h, byte 129 bits 6-7) indicate

that our module has power consumption greater than 1.5 W. When

the module is in low power mode, the module will reduce its power

consumption to less than 1.5 W while still maintaining the

functionality above. However, the Tx or Rx may not be operational in

this state.

The module will be in low power mode if the LPMode pin is in the

high state, or if the Power_over-ride bit is in the high state and the

Power_set bit is also high. The module will be in high power mode if

the LPMode pin is in the low state, or the Power_over- ride bit is high

and the Power_Set bit is low. Note that the default state for the

Power_over-ride bit is low.

A truth table for the relevant configurations of the LPMode and the

Power_over-ride and Power_set are shown in Table 1.

Table 1 Power Mode Truth Table

LPMode Power Over-ride Bit Power_set Bit Module Power

Allowed

1 0 X Low power

0 0 X High power

X 1 1 Low power

X 1 0 High power

At power up, the Power_over-ride and Power_set bits are set to 0.

ModPrsL: ModPrsL is pulled up to Vcc_Host on the host board and

grounded in the module. The ModPrsL is “Low” when the module

is inserted and “High” when the module is physically absent from

the host connector.

IntL: IntL is an output pin. “Low” indicates a possible module

operational fault or a status critical to the host system. The host

identies the source of the interrupt using the 2-wire serial

interface. The IntL pin is an open collector output and must be

pulled to host supply voltage on the host board

Application Schematics

An example application schematic (reference SFF 8679) showing

connections from a host IC and host power supply to the Lumentum

100G QSFP28 CWDM4 optical transceiver is shown in Figure 2.

QSFP28 CWDM4 modules are hot pluggable and active connections

are powered by individual power connection at 3.3 V nominal

voltage. Multiple modules can share a single 3.3 V power supply with

individual filtering. To limit wide band noise power, the host system

and module shall each meet a maximum of 2% peak-to-peak noise

when measured with a 1 MHz low pass filter. In addition, the host

system and the module shall each meet a maximum of 3% peak-to-

peak noise when measured with a filter from 1 MHz - 10 MHz.

A module will meet all electrical requirements and remain fully

operational in the presence of noise on the 3.3 V power supply.

Power supply filtering components should be placed as close to the

Vcc pins of the host connector as possible for optimal performance.

Note: Decoupling Capacitor values vary depending on the

application.

2.9 Electrical Input and Output Squelch Behavior

The Lumentum 100G QSFP28 Optical Transceiver is compliant to the Tx and Rx squelch behavior described in SFF-8636 section 6.6.2

and will be indicated in Page 00h, Byte 194, bit 0:3.

Rx(n)(p/n) are QSFP28 module receiver data outputs. Output squelch for loss of optical input signal, hereafter Rx Squelch, is supported

by the Lumentum QSFP28 transceiver. In the event of the optical signal on any channel becoming equal to or less than the level

required to assert LOS, then the receiver data output for that channel shall be squelched or disabled. In the squelched or disabled state

output impedance levels are maintained while the differential voltage swing shall be less than 50 mVpp.

In normal operation the default case has Rx Squelch active. Rx Squelch can be deactivated using Rx Squelch Disable through the 2-wire

serial interface. For the Lumentum 100G QSFP28 Optical Transceiver, squelch and output disable is controlled for each channel using

bytes 240 and 241 of page 03h. Writing a '1' in the Squelch Disable register (byte 240, page 03h) disables the squelch for the

associated channel. Writing a '1' in the Output Disable register (byte 241, page 03h) squelches the output of the associated channel.

When a '1' is written in both registers for a channel, the associated output is disabled.

The Lumentum 100G QSFP28 Optical Transceiver will disable Tx Squelch Function as default. Tx(n)(p/n) are QSFP28 module transmitter

data inputs and Tx Squelch is implemented to reduce OMA only (Page 00h, Byte 195, bit 2=0b). For details regarding Tx Squelch

behaviors, please contact Lumentum to learn more.

2.10 Module CTLE Behavior

The Lumentum 100G QSFP28 Optical Transceiver supports manual (provisional) equalization with non-readable CTLE gain. Please

contact Lumentum for details if automatic (adaptive) equalization is preferred.

2.11 Regulatory Compliance

The transceiver is RoHS 6/6 compliant and complies with international EMC (Electromagnetic Compatibility) and product safety

regulations and standards.

3.1 Package and Handling Instructions

Connector Covers

The Lumentum 100G QSFP28 Optical Transceiver is supplied with

an LC duplex receptacle. The connector plug supplied protects the

connector during standard manufacturing processes and handling

by preventing contamination from dust, aqueous solutions, body

oils, or airborne particles.

Note: It is recommended that the connector plug remain on

whenever the transceiver optical ber connector is not inserted.

Recommended Cleaning and De-Greasing Chemicals

Lumentum recommends the use of methyl, isopropyl and isobutyl

alcohols for cleaning.

Do not use halogenated hydrocarbons (e.g. trichloroethane,

ketones such as acetone, chloroform, ethyl acetate, MEK,

methylene chloride, methylene dichloride, phenol,

N-methylpyrolldone).

This product is not designed for aqueous wash.

Housing

The Lumentum QSFP28 Optical Transceiver housing is made from

zinc.

3.2 Electrostatic Discharge (ESD)

Handling

Normal ESD precautions are required during the handling of this

module. This transceiver is shipped in ESD protective packaging.

It should be removed from the packaging and otherwise handled

only in an ESD protected environment utilizing standard

grounded benches, oor mats, and wrist straps.

Test and Operation

In most applications, the optical connector will protrude through

the system chassis and be subjected to the same ESD

environment as the system. Once properly installed in the

system, this transceiver should meet and exceed common ESD

testing practices and fulll system ESD requirements.

Typical of optical transceivers, this module’s receiver contains a

highly sensitive optical detector and amplier which may

become temporarily saturated during an ESD strike. This could

result in a short burst of bit errors. Such an event might require

that the application re-acquire synchronization at the higher

layers (e.g. Serializer / Deserializer chip).

3.3 Laser Safety

The transceiver is certied as a Class 1 laser product per

international standard IEC 60825-1:2014 3rd edition and is

considered non-hazardous when operated within the limits of

this specication. This device complies with 21 CFR 1040.10

except for deviations pursuant to Laser Notice No. 50.

Caution

Operating this product in a manner inconsistent with intended

usage and specications may result in hazardous radiation

exposure.

Use of controls or adjustments or performance of procedures

other than these specied in this product datasheet may result

in hazardous radiation exposure.

Tampering with this laser product or operating this product

outside the limits of this specication may be considered an ‘act

of manufacturing’ and may require recertication of the

modied product.

Viewing the laser output with certain optical instruments (e.g.,

eye loupes, magniers, microscopes) within a distance of 100mm

may pose an eye hazard.
