Cisco SFP-25G-ER40-S Compatible 25GBASE-ER SFP28 1310nm 40km Duplex LC SMF DOM Optical Transceiver Module
For metro fronthaul aggregation and inter-site 25G, this ER module eliminates transport shelves: standard SFP28 ports now reach 40 kilometers.
A duplex LC interface and 1310nm optics keep the module compatible with standard outside-plant cabling, while DOM support lets operators watch optical levels degrade long before links fail.
