1625nm WDM for OTDR

This WDM coupler is used to combine or separate 1625nm channel with three triplex wavelength 1310nm, 1490nm and 1550nm. Using this device, 1625nm channel can be added into the existing triplex FTTH system.

    Gezhi Optical Fiber Filter WDM FTTX 1625nm is made by special optical components and advanced technology, it can deeply let 1600-1670nm wavelength pass but efficiently filter out 1250-1590nm 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
