According to the transmission distance, 25G optical modules can be divided into 25G SFP28 SR 100m, 25G SFP28 LR 10km, 25G SFP28 ER 40km, etc. In this article, ETU-LINK will focus on introducing the 25G SFP28 LR 10km optical module.

The 25G SFP28 LR 10km optical module has a working wavelength of 1310nm, dual LC connector, DFB laser and PIN photodetector, built-in CDR circuit in the receiving channel, the highest rate can reach 25.78Gbps, and the transmission distance can be up to 10KM through OS2 single-mode optical fiber .

The 25G SFP28 LR 10km optical module complies with SFP28 MSA, IEEE 802.3cc 25GBASE-LR Ethernet and CPRI/eCPRI standards, and the maximum power consumption is less than 1W. The materials used comply with RoHS environmental standards (lead-free).

25G SFP28 LR optical module can currently support commercial  (0℃-70℃) and industrial (-40℃-85℃) operating temperature range, and is applied to 25G Ethernet (25GBASE-LR) and 5G fronthaul CPRI/eCPRI internet.

ETU-LINK's 25G optical module is mainly used in 25G Ethernet, 100G (4 ×25Gbps) Ethernet, 5G network construction and other application scenarios of data center server and switch interconnection, help to upgrade the user network.
