Description
Arkoptics 9 Channel Single Fiber CWDM is a cost-effective and flexible passive WDM device based on TFF technology. This low insertion loss CWDM unit works in a pair to provide 9 bidirectional channels on a single strand of fiber, 9 CWDM wavelengths being used in each direction.
In conjunction with Arkoptics CWDM OADM and optical transceivers, etc., single fiber CWDM supports a wide range of architectures from simple point-to-point to amplified ring configurations. It can be used as either a multiplexer or demultiplexer (mux/demux). In accordance with the ITU-T G.694.1 100GHz grid, it maximizes the capacity of the C-band range.
The main fields of applications are the use in SDH (STM-1, STM-4, STM-16, STM- 64), IP (Fast Ethernet, Gigabit Ethernet, 10 Gigabit) ATM and storage (1G, 2G, 4G, 8G,10G Fiber Channel) networks.
9 Channel Single Fiber CWDM Solution
9 Bi-directional Channels Using Standard 18 Channel CWDM Band
CWDM single fiber solution is more efficient and economical for many applications and scenarios and provides the same performance and throughput, saving the fiber resources needed for WDM transport. 9 bi-directional channels using standard 18 channel CWDM band 1270-1590nm / 1290-1610nm, 20 nm spacing. It is passive, no electric power required, featuring low insertion loss and premium stability based on thin-film-filter technology. Low-profile modular design, fits in Arkoptics 2-slot 1U panel chassis.
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.
