CWDM system

Point-to-Point Network Construction

Network structure

This solution is designed to transmit multi-line signal in the fiber scarcity situation between 2 points. The whole system is supported by C5000 series chassis and W5000 series Module cards. 2-16 signals between 2 points can be transmitted by one or a pair of fiber, detailed information as below:

2.1.1 Overview
HiOSO C5000 series CWDM devices can effectively replace layout of optical cables, which improves bandwidth utilization at a low cost. 

It is applicable to the construction of short and medium-distance IP broadband Metropolitan Area Networks (MANS) and access networks, especially applicable to network carriers who: 
1) cannot lay optical cables conveniently , 
2) rent optical cables , 
3) do not have sufficient optical cables, 
4) want to improve the bandwidth utilization of optical cables.

HiOSO C5000 series devices are developed on the basis of CWDM technology, through which multiple wavelength channels with a wavelength interval of 20nm are multiplexed into one or a pair of fibers to implement signal transmission.

it can be used in point-to-point and point-to-multipoint application, and can also work with wavelength routers. With the application of non-cooling laser technology and EDFA technology, it has great cost advantage in building broadband MANS and access networks. 

It can provide interfaces in multiple data formats, such as E、FE、GE 、STM-1/4/16 interfaces and fiber channels.

External interface: Interface for out signal input; interface type can be RJ45 or fiber port, connecting with switches and fiber optical converters etc, to implement signal input.
Internal interface: CWDM signal conversion port; output signal wavelengths are CWDM wave band (1470nm-1610nm),  easy  for multiplexing and output.
COM: Multiplexing signal output port, a port for signal output after multiplexing; interface type is SC.

Remarks: Module cards support hot-swap; directly replacing and increasing new cards are supportable.
