1RU Rack Chassis Wdm Fiber Optic Multiplexer LC/UPC Duplex For CATV Links
GEZHI PhotonicsCoarse Wavelength Division Multiplexing units are a flexible plug-and-play network solution that allows network operators to cost effectively implement point to point or ring based WDM optical networks.
Our CWDM MUX DEMUX are perfectly suited to transport PDH, SDH / SONET, ETHERNET services over WWDM, CWDM and DWDM in optical metro edge and access networks.
Front panel of 8ch 1310-1610nm CWDM Mux Demux, type B
Connectors, located on the front of the CWDM Mux Demux modules, are labeled and use the same color-coding that is used to indicate the wavelength of the individual CWDM transceivers. The connectors at the end of CWDM transceivers are similarly color-coded, which simplifies the process of connecting a CWDM transceiver to its associated device port.
- Passive, no electric power required
- Standard 8-channel CWDM band 1310–1610 nm on a single fiber, 20 nm spacing
- Duplex LC/UPC connectors, easily support duplex patch cables between the transceiver and passive unit
- 1RU Rack-Mount Chassis
- Channel Insertion Loss: < 2.5dB
- Return Loss: ≥ 45dB
- Operating Temperature: -10~70°C
GEZHI Photonics quality assurance by using high-quality CWDM multiplexers
Our components fulfill or exceed standard market specifications for optical components. It may still not be entirely obvious how different parameters like isolation are more closely defined. The following diagram illustrates the most important parameters, following the "red box model", in accordance with ITU. The channel, including its bandwidth and isolation as defined by the component specifications, delineates a box. The measured transmission spectrum of each channel has to be above the box. Under no circumstances can it interfere with any neighboring box (channel). Therefore, isolation and insertion losses have to be maintained within the borders set out by the defined center wavelengths and bandwidth.
