Product Details
18 Channels Passive CWDM Mux Demux With Monitor Port , Pigtailed
Module
18ch CWDM Mux+Demux in one splice/pigtailed ABS module,
1270-1610nm, w/monitor port, duplex LC/UPC , 2.0mm diamater
GEZHI Photonics Coarse Wavelength Division Multiplexing (CWDM) is
an excellent choice for increasing bandwidth capacity while keeping
costs down. The fs.com splice/pigtailed ABS module family, based on
standard Thin Film Filter (TFF) technology with a proprietary
packaging, offers you smallest component dimensions combined with
an outstanding performance and reliability.Our CWDM MUX DEMUX are
perfectly suited to transport PDH, SDH / SONET, ETHERNET services
over WDM, CWDM and DWDM in optical metro edge and access networks.
Labeling on each pigtail, indicate the wavelength of the CWDM
transceivers
Each fiber pigtails of inputs and outputs are labeled with
wavelengths that is used to indicate the wavelengh of the
individual CWDM transceivers. There are four holes to fix the
pigtailed module with your device.

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.
Saving on fiber optic lines by using passive CWDM multiplexer/demultiplexer
