LGX Cassette Optical Multiplexer And Demultiple 1510~1570nm
Wavelength
4ch CWDM Mux+Demux plug-and-play cassette, 1510-1570nm, duplex
LC/UPC
GEZHI PHOTONICS Coarse 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 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.

- 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.
