The 18 channels Coarse Wavelength Division Multiplexer (CWDM)

The 18 channels Coarse Wavelength Division Multiplexer (CWDM). Sopto is a manufacturer specializing in the production of a full range of wavelength division multiplexer which includes the coarse wavelength division multiplexer (CWDM) and the dense wavelength division multiplexer (DWDM).


The wavelength division multiplexer (WDM) has become the solution to the shortage and expansion of long-distance signal transmission cable. The wavelength division multiplexer (WDM) is widely used in Gigabit & 10G Ethernet, SDH / SONET, ATM, ESCON, FTTx and CATV system.


The wavelength division multiplexer (WDM) produced by Sopto is used the thin-film filter technology. It has the characteristics of low insertion loss, high channel isolation, wide bandwidth and low temperature sensitivity.


Generally, the coarse wavelength division multiplexer (CWDM) can be divided into 4 channels CWDM, 8 channels CWDM, 16 channels CWDM, or up to 18 channels CWDM. For the low insertion loss requirements of CWDM system, the module can be added jumper to reduce the insertion loss of each channel.


The ordinary package of CWDM is divided into: ABS box, LGX cassette and 19-inch 1U chassis.

SFP Module

SFP module is the most widely use product.  SFP module inherits the hot swappable characteristics of GBIC and also draws on the miniaturization advantages of the SFF module with the LC connector. SFP module is reduced the volume and consumption by designing the CDR and EDC outside the module.SFP module is used to connect network devices, such as, switches, routers and others. It is widely applied to the telecommunications and data communications.

SFF Module

SFF module is another branch of the development of the fiber optic transceiver module. Currently, the SFF modules are widely used in the ONU of EPON systems. Since the ONU products of EPON systems are usually placed in the client which needs the ONUs be fixed, not hot-pluggable, the SFF is popular in EPON systems. And with the rapid development of EPNO technology, the SFF market share is also gradually expanded.   


XENPAK is an important step in the evolution of the optical modules. The XENPAK architecture provides a XAUI interface for the Media Access Controller.Compared with not hot-pluggable modules, XENPAK modules is very attractive. But is can’t meet some important market demand. The power consumption of XENPAK is usually 10W, which will cause a certain influence to the structure size because it increase the cost of manufacturing printed circuit board and reduce the precious line space.
