Application of 10G SFP+CWDM Wavelength Division Module in MAN

Nowadays, with the rapid development of data services, the speed of IP network convergence is accelerating, so it is very important to expand the network capacity. In the construction of MAN, there is a general problem of optical fiber shortage. Because the number of channels required by MAN expansion is relatively small compared with that of the trunk system, and the distance is relatively short, there is no need for optical amplification, making the CWDM technology scheme particularly suitable for MAN optical transmission network.

In the application of CWDM system in MAN, because it is not long-distance transmission, the attenuation of oxygen and hydrogen ions is small, so its wavelength design is all optical (1270nm-1610nm). CWDM technology realizes wavelength division multiplexing in the full wavelength range by reducing the requirement of wavelength window, and adopts 20nm wavelength interval and wider wavelength interval, which greatly simplifies the structure of wavelength division multiplexing/demultiplexer. Now, let's introduce the 10G SFP+CWDM wave splitter module:

1、10G CWDM SFP+ 1270nm-1610nm 10km(ESCxxX-3LCD10)

2、10G CWDM SFP+ 1270nm-1610nm 20km(ESCxxX-3LCD20)

These two 10G CWDM optical modules adopt hot pluggable SFP+package, dual fiber LC interface, optional working wavelength of 1270nm-1610nm, equipped with DFB laser and APD photodetector, which comply with SFP28 MSA and 10G Ethernet standards, with the maximum speed up to 11.1Gbps, and can transmit 10/20km through single-mode fiber OS2 at the farthest.

3、10G CWDM SFP+ 1470nm-1610nm 40km(ESCxxX-3LCD40)

4、10G CWDM SFP+ 1470nm-1610nm 80km(ESCxxX-3LCD80)

These two 10G CWDM optical modules adopt hot pluggable SFP+package, dual fiber LC interface, optional operating wavelength of 1470nm-1610nm, equipped with EML laser and APD photodetector, which comply with SFP28 MSA and 10G Ethernet standards, with the highest speed up to 11.1Gbps, and can transmit 40/80km through single-mode optical fiber OS2 at most.
