Mini Filter WDM Device(Compact 1×2 FWDM) use stable Thin Film Filters and advanced packaging technology to achieve good performance and excellent environmental stability. Mini Filter WDM Device have a smalle package. It is characterized by high performance fiber optic transmission simultaneously at low loss insertion loss and excellent temperature stability. It is designed to separate or combine optical signals transmitted on different wavelengths.
Mini Size 1×2 Triplexer FWDM is designed for the “triple-play” fiber to the home (FTTH) systems. It can be used to mux/demux three wavelengths at 1310nm, 1490nm and 1550nm that carry the voice, data and video services. This device has 1 to 2 port configuration. 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. This device is bi-directional. It supports optical traffic in both directions. Customer can specify the allocation of the wavelengths for the reflection and passing through bands.
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.
