FIBER OPTICS
The 1614W 1310 nm wideband wireless DFB laser modules are
designed for analog applications requiring an operational bandwidth
between 5 MHz and 2700 MHz. The highly linear, OC-48 pinout compatible
devices feature up to 25 mW of output power with superior performance over an
enhanced operating 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.
