According to the transmission distance, 25G optical modulescan be divided into 25G SFP28 SR 100m, 25G SFP28 LR 10km, 25G SFP28 ER 40km, etc. In this article, Walsun will focus on introducing the 25G SFP28 LR 10km optical module.
The 25G SFP28 LR 10km optical modulehas 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 10KMthrough OS2single-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 modulecan 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.
Walsun’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.
