ETU-LINK will introduce to you what is 10G SFP+ DWDM optical module and its advantages.

The traditional optical fiber communication system is transmits one optical signal in one optical fiber. This method actually only uses a part of the optical fiber bandwidth. In order to make full use of the huge bandwidth resources of the optical fiber and increase the transmission capacity of the optical fiber, dense wavelength division DWDM A new generation of optical fiber communication technology with technology as the core was born.

ETU-LINK will introduce the models of 10G SFP+ DWDM optical modules.

1. 10G DWDM SFP+ C17-C61 40km(ESDxxX-3LCD40)

It adopts hot-pluggable SFP+ package, dual-fiber LC interface, optional fixed wavelength C-band C17-C61 (interval 50/100GHz), equipped with EML laser and PIN photodetector, operating temperature range has commercial grade (0℃- 70°C) and industrial grade (-40°C-85°C) optional, it complies with SFP28 MSA and 10G Ethernet standards, the maximum rate is up to 11.3Gbps, and the maximum transmission distance is 40 kilometers through single-mode optical fiber OS2.

2. 10G DWDM SFP+ C17-C61 80km(ESDxxX-3LCD80)

It adopts hot Pluggable SFP+ package, dual-fiber LC interface, optional fixed wavelength C-band C17-C61 (interval 50/100GHz), equipped with EML laser and PIN photo detector, it complies with SFP28 MSA and 10G Ethernet standards, The maximum rate is as high as 11.3Gbps, and the maximum transmission distance is 80 kilometers through single-mode optical fiber OS2.

3. 10G Tunable DWDM SFP+ 80km

The module supports the rate from 9.95Gbps to 11.3Gbps, supports the entire C-band adjustable, 100GHz interval. The module complies with the "SFP+ Enhanced Small Form Factor Pluggable Module" SFF-8431 version 4.1 standard. The SFP+ module with adjustable wavelength has built-in PIN or APD, clipping or linear electrical interface. The difference between DWDM with tunable wavelength and ordinary DWDM optical module is that the wavelength band of ordinary optical module is fixed, while the adjustable wavelength is adaptive between 1528.77nm-1563.86nm.

In network expansion and development, there is no need to modify the optical cable, only the optical transmitter and optical receiver need to be replaced. It is an ideal means of capacity expansion and a convenient means of introducing broadband services, and any additional wavelength can be introduced by adding an additional wavelength. Desired new business or new capacity. In addition, the DWDM system is compatible with the future all-optical network, and may realize a transparent and highly survivable all-optical network on the basis of the established DWDM system in the future.
