25G optical module is an optical module with a transmission rate of 25Gbps, which is mainly used in 25G Ethernet and 100g (4×25Gbps) Ethernet. Encapsulated as SFP28, its function is to interconnect servers and switches in the data center.
With the rapid development of the Internet, cloud computing and big data, the construction of IT infrastructure data centers is further accelerated, among which 25G SFP28 SR optical modules and 25G SFP28 LR optical modules are favored for their ability to provide cost-effective 25G and 100G network solutions. The center of the majority of users of all ages. Next, HTF will show you 25G SFP28.
Telecom Buyer should know more about 25G SFP28, At present, the common ones are 25G SFP28 SR, 25G SFP28 LR, 25G SFP28 ER, 25G SFP28 CWDM, 25G SFP28 DWDM, 25G SFP28 BiDi. The above product parameters can be seen in the table form.
25G SFP28 conventional optical modules include SR, LR, and ER. The 25G SFP28 SR optical module is a 25G optical module with a working wavelength of 850nm. Its internal transmitter is a vertical cavity surface emitting laser. Therefore, it needs to be used with 50/125µm OM3/OM4 multimode fiber. The transmission distance is 70 meters when used with OM3 and 100 meters when used with OM4.
25G SFP28 LR and 25G SFP28 ER are single-mode optical modules, which need to be used together with single-mode optical fiber patch cord OS2.
25G SFP28 color optical module includes CWDM SFP28 optical module, DWDM SFP28 optical module, and the working wavelength of 25G CWDM SFP28 optical module is 1271-1331nm. It is mainly used in the 5G fronthaul bearer network, and can be transmitted up to 10 kilometers through single-mode fiber OS2.
