Description
CWDM is an attractive solution for carriers who need to upgrade their networks to accommodate current or future traffic needs while minimizing the use of valuable fiber strands. The escalated demands for bandwidth and capacity are driving networks to look for agile, cost-effective data optical transport solutions.
The CWDM 18 Channel Mux Demux is a cost-effective, flexible, and suitable for short-distance transmission passive WDM device based on TFF (Thin Film Filter). This unit can be used as either a multiplexer or de-multiplexer(mux/demux). In accordance with the ITU-T G.694.2, it maximizes the capacity of the C-band range. In conjunction with Arkoptics CWDM OADM and optical transceivers, etc., this Mux Demux supports a wide range of architectures from simple point-to-point to amplified ring configurations.

Rigorous Application Test
Arkoptics performs rigorous application testing in end-use conditions.

Clean Fiber End-Face
Each port will be inspected to ensure a super clean fiber surface after mounted.

Function Ports Optional
Monitoring port, 1310nm wide band port and expansion port are available.

Adjustable Mounting Bracket
Adjustable mounting brackets extend infinitely to fit rack mounting depth.
18 Channels CWDM Mux Demux
Flexible mix of 1G/10G/25G/40G/100G/200G Ethernet, 8G/16G FC, SAN, OTN, SDH/SONET and native video services
The 1270-1610nm channel port for ITU grid CWDM traffic, Monitor port for optical performance monitoring. 18 Channel CWDM supports up to 18 wavelength channels transmitted through a fiber at the same time. To achieve this, the different wavelengths of each channel are 20nm apart. CWDM technology offers a convenient and cost-efficient solution for shorter distances of up to 70 kilometers.
Single Fiber CWDM Mux Demux
The single fiber CWDM Mux Demux can carry signals through only one fiber to realize simultaneous transmission of optical signals in two directions, and the signals in two directions cannot be the same wavelength. In both single and dual fiber system, CWDM Mux Demux must work in pairs for transmission.
Dual Fiber CWDM Mux Demux
Different with single fiber, the dual fiber CWDM Mux Demux carries signals with two fibers. One fiber is used for the transmit direction and the other is used for the receive direction. In dual fiber transmission system, the same wavelength is normally used in both the transmit and receive directions.
