FTTX on line testing
OTDR monitor module
1625/1650nm filter system
1650nm FWDM
Gezhi Optical Fiber Filter WDM FTTX 1650nm is made by special optical components and advanced technology, it can deeply let 1650nm band wavelength pass but efficiently filter out 1250-1625nm wavelength. This product is mainly used in optical fiber on-line testing. It is ideal component of 1625/1650nm optical fiber filtering.
It enable testing fibers that are bearing traffic with an OTDR by inserting an out-of-band wavelength (1625 or 1650 nm). The OTDR signal is added to the data signal by using a wavelength division multiplexer (WDM). At the other fiber extremity, a filter blocks the OTDR signal. When OTDR measurement range can cover more than one fiber span, a bypass can extend the OTDR signal to the adjacent span
