2 Channels Acess Network CWDM Mux Demux ABS Pigtailed Module
GEZHI Photonics CWDM (Coarse Wave Division Multiplexing) MUX/DEMUX
(Multiplexer/Demultiplexer) is a flexible, low-cost solution that
enables the expansion of existing fiber capacity. GEZHI Photonics
CWDM MUX/DEMUX modules support ITU-T G694.2 CWDM wavelengths
between 1270 nm to 1610 nm in 20 nm increments.
They accept any data rate and any protocol on any port up to 10
Gpbs, also 40 Gbps and 100 Gbps. The CWDM MUX & DEMUX over simple
fiber is capable of coming up to 18 optical signals into a single
fiber and supports a broad range of architectures, ranging from
scalable point-to-point links to two fiber protected rings. We
offer a complete portfolio of CWDM Mux Demux Module over dual fiber or simplex fiber, with package types of Plastic ABS
module cassette, 19" rack mountable box or market-standard LGX
packaging, custom wavelength channels are available.

GEZHI Photonics provides a complete portfolio of CWDM Mux Demux and Optical Add Drop Multiplexer(OADM) units to suit all applications such as: Gigabit & 10G Ethernet,
SDH/SONET, ATM, ESCON, Fibre Channel, FTTx and CATV. And we provide
optional port configurations such as: Express Port, Monitor Port,1310nm passband port and 1550nm port for these multiplexers according to customer
choice.
Front Panel Details
A Common port:
- LC, SC, ST and FC connectors available.
B Standard port 1310nm:
- Allows a legacy 1310nm signal to pass. That is to say, it can carry
LR optics, LX optics etc.
- LC, SC, ST and FC connectors available.
C Standard port 1550nm:
- Allows a legacy 1550nm signal to pass. That is to say, it can carry
ER optics, ZR optics, LX optics, ZX optics etc.
- LC, SC, ST and FC connectors available.
D Mux/Demux port for specific wavelengths:
- LC, SC, ST and FC connectors available.
- Compliant with the ITU G.657A1 standard as default.
E Express port:
- Enables the cascading of two CWDM mux/demux modules, doubling the
channel capacity on the common fiber link.
- Channel Isolation is 15dB as default, 16dB ~40dB available on
request.
- LC, SC, ST and FC connectors available.
F Monitor port:
- Connects measurement/monitoring equipment, such as power meters or
network analyzers, to the module outputs.
- When finished monitoring, disconnect the instruments and the
network is left undisturbed.
- LC, SC, ST and FC connectors available.
- Tap percentage is 5% as default, 1%, 2%, 3%, or 10% available on
request.
NOTE:
Actual layout depends on the chosen connector type as well as other
factors. However, the principal scheme stays the sameWe provide
optional port configurations such as: Express Port, Monitor Port,
1310nm passband port and 1550nm port for these multiplexers
according to customer choice, When using with 1310nm legacy
SDH/SONET, CWDM wavelengths 1270, 1290, 1310, 1330 and 1350nm
should not be used.When using with 1550nm legacy SDN/SONET, CWDM
wavelengths 1510, 1530, 1550, 1570 and 1590nm should not be used.
