How to wire CCWDM multiplexer?

A three-port filter for a specific wavelength of CWDM whose wavelength channel consists of two lenses and a TFF matched to that specific wavelength. The reflection port of each filter is connected to the common port of the next filter, and the filters are connected through optical fiber connectors, which is a CWDM multiplexer.

The principle of CCWDM is to use the input lens to focus the optical signals with wavelengths λ1, λ2...λn on the input fiber onto the first filter; the optical signal with wavelength λ1 passes through the first filter and is coupled to the optical fiber via the first output lens. In the first output fiber, the optical signal with wavelength λ1 is separated; the remaining optical signals are reflected from the first glass slide to the next glass slide for optical signal separation; and so on until all signals are separated. The coupling between wavelength channels is realized in the form of straight rays taking a zigzag route.

HTF has achieved mass production of CCWDM wavelength division multiplexers, and the quality and price are guaranteed. If you purchase our multiplexer, we will also provide you with the wiring diagram of the multiplexer and optical module for your reference.
