FWDM Module 1310nm 1490nm 1550nm, FC/APC, ABS Box Type

3 port filter WDM, ABS box package, 2.0mm fanout legs, with FC/APC connectors, 1310/1490/1550nm, customized output wavelength

General Details

FOCONEC supplies ABS Box Type FWDM Module 1310 / 1490 / 1550 nm, harnessed 2.0/3.0mm fanout legs with FC/APC connectors terminated.

Our Filter Wavelength Division Multiplexer – FWDM module has a 1 to 2 port configuration. It multiplexes and demultiplexes three wavelengths at 1310nm, 1490nm and 1550nm that carry the voice, data and video services, so to realize the “triple-play”  FTTH systems.

All three wavelengths are fed into the device through the common input port. One wavelength is reflected from one output port, and the other two wavelengths pass through the device at the other output port. Customers can specify the allocation of the wavelengths for the reflection and pass-through bands.

Filter Wavelength Division Multiplexer provides low insertion loss, high channel isolation, low-temperature sensitivity, and epoxy free optical path.

Except for 1310 / 1490 / 1550 nm, our Filter WDMs are available with customized wavelengths and fiber optic connector configurations.
