1×3 Triplexer WDM for FTTH

1x3 triplexer WDM coupler is designed for the "triple-play" fiber-to-the-home (FTTH) systems. It can be used to combine or separate (multiplex or demultiplex) three channels at wavelengths of 1310nm, 1490nm and 1550nm, which carry voice, video and data services on one single optical fiber.

1×3 triplexer WDM coupler is designed for the “triple-play” fiber-to-the-home (FTTH) systems. It can be used to combine or separate (multiplex or demultiplex) three channels at wavelengths of 1310nm, 1490nm and 1550nm, which carry voice, video and data services on one single optical fiber. This component is equivalent of cascading two 1×2 triplexer WDM filters.
This device has one input to three outputs configuration. All three wavelengths are fed into the device through the common input port. Each wavelength is filtered out from one of the three output ports, individually. This device supports bi-directional transmission of any channels.

We also provide special modules with multiple WDM couplers and/or standard couplers packed together, based on customer’s design. Please contact us directly for quote.

The products are Telcordia GR-1221/1209-CORE qualified, and RoHS compliant.
