Cisco SFP-GLC-LH-SMD
Cisco GLC-LH-SMD 1000BASE-LX/LH SFP is made for Both Multimode and Single-Mode Fibers.
The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single-mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers. When used over legacy multimode fiber type, the transmitter should be coupled through a mode conditioning patch cable. 1300-nm wavelength, extended operating temperature range and DOM support, dual LC/PC connector.
Huawei 25G Sfp
Huawei SFP-25G-SR Module adopts hot-swappable SFP28 package, working wavelength is 850nm, it is a full-duplex transceiver module. Its maximum speed is up to 25.78Gbps, dual LC optical ports, and the transmission distance through multimode fiber can reach up to 70m (OM3) or 100m (OM4). SFP-25G-SR optical modules are mainly used in 25G data centers and 5G fronthaul CPRI/eCPRI networks. 25G network is an ideal solution for 10G network upgrade. On the one hand, 25G network is complementary to 100G network, but the cost is much lower than that of 100G network. On the other hand, compared with 10G network, 25G network requires ToR switches and cables. The number is less. At present, SFP-25G-LR optical modules have been widely used in 25G data centers.
