SDLO-1700-200 - JDS Uniphase

The JDS Uniphase 1700 Series embraces an

elegant solution to one of the biggest concerns of

EDFA designers,“heat dissipation”. These highly

efficient pump modules consume less than one

half of the electr ical power than other 980 nm

pump modules at the same optical power levels.

The 1700 Series are used in a variety of applica-

tions where heat dissipation is a concern. These

applications include: wideband er bium doped fiber

amplifiers (EDFA) in dense wavelength division

multiplexed (DWDM) fiber optic networks a nd

narrow band erbium doped fiber amplets.

Incor porated into these pump modules is our

cutting-edge 6540 laser diodes, which possess

superior reliability and thermal perfor mance.

These laser modules are stabilized with fiber Bragg

grating to enhance the performance of EDFA.

Safety and Operating Considerations

The laser light emitted from this laser diode is

invisible and may be harmful to the h uman ey e.

Avoid looking directly into the fiber when the

device is in operation.

CAUTION: THE USE OF OPTICAL INSTRU-

MENTS WITH THIS PRODUCT WILL

INCREASE EYE HAZARD.

Operating the laser diode outside of its maxi-

mum ratings may cause device failure or a safe-

ty hazard.Po w er supplies used with the compo-

nent must be employ ed such that the maximum

peak optical power cannot be exceeded.

CW laser diodes may be damaged by excessive

drive current or switching transients. When

using power supplies, the laser diode should be

connected with the main pow er on and the out-

put voltage at zero. The current should be

increased slowly while monitoring the laser

diode output power and the drive current.

Careful attention to heatsinking and proper

mounting of this device is required to insure

specified performance over its operating life. To

maximize thermal transfer to the heatsink, the

heatsink mounting surface must be flat to within

.001”and the mounting screws must be torqued

down to 1.5 in.-lb.

ESD PROTECTION — Electro-static discharge

is the primary cause of unexpected laser diode

failure. Take extreme precaution to prevent

ESD. Use wrist st raps, grounded work surfaces,

and rigorous anti-static techniques when han-

dling laser diodes.

User Safety

21 CFR 1040.10 Compliance

Because of the small size of these devices, each of the labels shown is attached to the individual

shipping container.They are illustrated here to comply with 21 CFR 1040.10 as applicable under

the radiations control for health and safety act of 1968.
