1270nm DFB Coaxial Pigtail Laser Diode
Product Description
Product Detail
1. Summary of 1270nm DFB Coaxial Pigtail Laser Diode
The 1270nm DFB Coaxial Pigtail Laser Diode series of MultiQuantum Well (MQW) Distributed Feedback (DFB) lasers have been designed specifically to satisfy the requirements of SONET CWDM transmission. The devices feature high output power and wide operating temperature range. Their uncooled, hermetically sealed, coaxial fiber pigtailed packages are a cost-effective means of providing a high-speed light source for intermediate-reach and long-reach applications.
