Description
The FWDM 1650nm Monitoring Filter is designed for Optical Fiber Cable Line Monitoring Systems and PON Data Systems. Using Thin Film Filter (TFF) technology, it separates OTDR monitoring wavelengths (1600–1670nm) from PON service wavelengths (1260–1580nm), allowing both monitoring and service signals to operate on the same optical fiber.
Featuring low insertion loss, high channel isolation and stable performance, the FWDM is suitable for FTTH, GPON, XGS-PON, CATV and OTDR monitoring applications.
Key Features
- Wide bandwidth
- Low insertion loss
- High channel isolation
- Exceptional reliability and stability
Applications
- Optical amplifiers
- CATV
- OTDR
