Cisco GLC-LH-SMD SFP Gigabit Ethernet Optical Fiber (mini-GBIC) Module
The commerce standard Cisco (SFP) Small Form-Factor Pluggable Gigabit Interface Converter joins your switches and routers to the network. Singlemode fiber (SMF) has far close-fitting tolerances for optics used. The core is minor and the laser wavelength is tighter. Singlemode SFPs (SMF SFPs) work primarily in 1310nm and 1550nm wavelength and is generally used in extended distances transmission environment reaching 2km, 10km, 40km, 60km, 80km and 120km.
