3.0 Connector Pin Assignment
In an active optical version of the CX4-QSFP+ cable assembly, certain ground pins are repurposed to provide power
and other control signaling. A CX4-QSFP+ hybrid active optical module requires a 3.3Volt power supply at each
end. On the CX4 side, this voltage supply is provided through pin G8 which is normally a ground pin in an
equivalent copper cable. It is used to provide electrical power to the opto-electronics inside the module. The host
uses G7, Type_Sense (labeled ‘TSense’ in the diagram below), to detect whether the module is an active of passive
variety. If the host detects a ground it automatically assumes the module is passive variety and thus requires no
electrical power. The 5K-Ohm resister allows the host to develop the appropriate voltage across a voltage
comparator circuit to detect that the module is active version and then automatically supplies power to pin G8.
3.1 Type Sense (TSense)
The Type_Sense pin on the module connector is an input pin. It is connected to a 5K-Ohm resister connected to
ground. The host system uses this line to detect whether this is an active optical module and thus provides power via
the voltage input pin G8.
3.2 Output Disable (ODIS)
The ODIS line is an input line to the module; it is used by the host system to switch OFF all the lasers. To turn ON
all the lasers the ODIS line must be kept low by the host system. The lasers turn OFF as soon as the ODIS line is
taken high. The module provides an internal 5K-Ohm pull-up resister to Vcc_In.

3.3 Fault
In normal operation, the CX4 module is able to respond to various fault conditions and signal them via the LEDS
and the Fault line on the CX4 connector. The following conditions are recognized:
• RX loss-of-signal. If the Receiver IC detects loss-of-signal on one or more channels then the module will
turn ON the Red LED and pull the fault line low to ground. When the fault is cleared, the Red LED will
turn OFF and the fault line will be pulled low to ground.
• TX fault: If the transmitter detects a transmit fault (laser short or open circuit) it will alternately flashes the
Red and Green LEDs and pulls the fault line low. The module must then be power cycled to continue.
Note: If no fault has occurred then the module will release the Fault line (open-collector output). The host
system is required to supply the recommended 5K-Ohm pull-up resister to this output line.
