EMCORE 1615A

1615A 1310 nm DFB Laser Module
DATASHEET | JULY 2013
FIBER OPTICS
The 1615A 1310 nm DFB laser modules are designed for both wireless and
distributed antenna system applications. This highly-linear OC-48 pinout
compatible device delivers superior distortion performance over an enhanced
temperature range of -40C to +85C.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent
damage to the device. These are absolute stress ratings only. Functional
operation of the device is not implied at these or any other conditions in excess of
those given in the operational sections of the data sheet. Exposure to absolute
maximum ratings for extended periods can adversely affect device reliability.

In order to prevent reflection-induced distortion, the laser must be connected to an optical cable having a return
loss of at least 55 dB for discrete reflections and 30 dB for distributed reflections.
