Although 40 GBIT/s and 100 GBIT/s data centers are developing rapidly, 10 GBIT/s optical modules are in high demand in most application scenarios. For example, the computer rooms of many schools, organizations, and companies are still based on 10 GBIT/s Ethernet. Among them, 10 GBIT/s SFP+ optical modules occupy the largest market share. This article is easy to day light communication (ETU-link) for you to introduce the 10G SFP+ 40KM optical module.

1. 10G SFP+ 40KM optical module（1310nm）

10G SFP+ 40KM optical module equipped with 1310nmDFB laser and PIN detector, duplex LC interface, the highest transmission rate of 10.3g, SFP+ MSA and 10G Ethernet standards, the transmission distance through single-mode fiber up to 40KM.

2. 10G SFP+ 40KM optical module（1550nm）

10G SFP+ 40KM optical module, also known as 10G ER in the industry, is equipped with 1550nmEML laser and PIN detector, duplex LC interface, the highest transmission rate of 10.3g, in line with SFP+ MSA and 10G Ethernet standards, the transmission distance through single-mode fiber up to 40KM.

A 10G ER optical module is used to connect long-distance network devices. In general, a40G ER optical module is inserted into a 10G switch and then into a duplex LC single-mode OS2 patch cord. The other end of the patch cord is connected to a distribution frame, which is usually connected to underground optical cables to achieve long-distance transmission. The connection diagram is shown below.

3. 10G SFP+ BIDI 40KM optical module（1270/1330nm）
