Signal Distribution in L-Band and

Wireless Remoting Links

High Linearity, Low Power Fiber Links

Features

Linear DFB Laser Design

Ouput Power Up to 10 dBm Available

Bandwidth > 4000 MHz

RoHS Compliance

Optical Isolator

Low Power Consumption

Monitor Photodiode

EMCORE’s Model 1933 DFB lasers offer a low cost solution for linear fiber optic

links. These components can be cooled with external thermo-electric coolers for

high stability, or run without TEC’s to reduce power consumption. The DFB laser

builds upon Ortel’s long history of high performance, leading edge designs in

CATV, wireless, and high speed digital applications. The laser diode devices are

packaged in a compact hermetic assembly together with monitor photodiode and

isolator, for flexible integration into various transmitter configurations.
