DFB Butterfly Laser Diodes PM Fiber 1550nm Select Wavelength Laser Diodes

 

Product Description:

The SWLD series laser diodes cover customer selection of large wavelengths range from 1260nm to 1650nm which are fabricated in a hermetically sealed 14-pin butterfly package. The laser diodes contains thermoelectric cooler (TEC), thermistor, monitor photodiode to secure high quality laser performance.

 

The Laser Diodes wavelength of 1550±2nm, Output power: ≥10mW, Pigtail Type: PMF 1550 fiber with 900um loose tube, 1.0m, FC/APC connector. Our laser products are Telcordia GR-468 qualified, and in compliance with RoHS Directives.

 

Applications:

LAN, WAN and metro networks

C/DWDM systems

Fiberoptic sensors

Laser sources

CATV systems

 

Features:

High output power(≥10mW)

High-performance, multiquantum well (MQW) distributed-feedback (DFB) laser

Industry-standard, 14-pin butterfly package

Built-in TEC, no optical isolator

λc of 1550±2nm

Reliability: Telcordia GR-468. RoHS 

 

Performance Specifications:

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.
