Description
Arkoptics dual fiber 8 channel CWDM Mux Demux allows you to multiplex and demultiplex eight separate channels into one pair of fiber. The 8 channel port for ITU grid CWDM traffic, Upgrade port can be used to connect another CWDM Mux Demux for wavelength expansion, and Monitor port can be connected with monitoring devices to test the power of the signal without service interruption, which enables users the ability to monitor and troubleshoot networks. It's protocol and rate transparent supporting different applications such as 1G/10G/25G Ethernet, SDH/SONET and 8/4/2/1G Fiber Channel across the same fiber link.
With modular design, the 8 channel CWDM Mux can be combined with CWDM and DWDM modules, OADMs and MTP MPO cassettes in Arkoptics multi-function 1U enclosures. Also it can support 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.

TFF Technology CWDM
Thin-film filters are usually composed of multiple film layers of different thicknesses, with a certain regularity and specific reflectivity, allowing specific wavelengths to reflect in the thin film, while other wavelengths pass through these layers, achieving the separation and multiplexing of signals. TFF technology features its simple structure, small size, low cost, and high reliability.
Free-Space Technology CWDM
Different with the conventional Thin Film Filter CWDM multiplexer, Free-Space technology CWDM multiplexer uses light propagating in free space to wirelessly transmit data. This unique technology and great workmanship help it with lower insertion loss. However, the disadvantages of Free-Space technology are its stability at industrial temperature applications and higher link loss.
