2.5G 1650nm DFB Pigtail Diode Laser

0.0/5 rating (0 votes)

Description

F-tone Networks 2.5G 1650nm DFB pigtail diode laser 1mw is generally applied for stabilizing or modulating light source. In addition,the high stability laser source can be used for testing apparatus and OTDR equipment.
The laser diode is composed of a CWDM-DFB chip,built-in isolator, built-in monitor photodiode,4-pin coaxial package, and optional SC,FC,ST,or LC optical fiber connector. Customers can select the length of optical fiber and pin definition based on actual demand. The output power is available from 1MW.
