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.
