Product Overview of 3 Ports FWDM
Excellent Thermal Stability 3 ports T1625nm R1310/1490/1550nm FWDM for OTDR
3 ports T1625nm R1310/1490/1550nm FWDM
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.
