Select Wavelength LD (SWLD)-Series

Product Description: SWLD laser diodes cover customer selection of large wavelengths from 1260nm to 1650nm which are fabricated in a hermetic sealed 14-pin butterfly package. The laser diodes contain thermoelectric cooler (TEC), thermistor, monitor PD and optical isolator to secure high quality laser performance. We also have full customer selection of output powers, package types and output fibers of SM fibers, PM fibers and other special fibers. 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

Features:

• High output power(10^100mW) 
• High-performance, multiquantum well (MQW) distributed-feedback (DFB) laser 
• Industry-standard, 14-pin butterfly package 
• Built-in TEC and optical isolator
• Customer selection of wavelengths
