TRENDnet TE100-MGBS20 Fast Ethernet SFP Transceiver 100BASE-FX 1310 nm LC Single-Mode up to 20 km
TRENDnet TE100-MGBS20 — 100BASE-FX Single-Mode SFP, 20 km
The TRENDnet TE100-MGBS20 is a Fast Ethernet SFP module: 100BASE-FX at 1310 nm over single-mode fibre, up to 20 km, through a duplex LC connection. It is for switches and media converters whose SFP slots run 100 Mbps optics, typically for long links to older equipment, cameras and industrial devices. It is not a Gigabit module, despite some listings describing it as 1000BASE-LX. In practice, single-mode optics are the choice when a link leaves the building or runs more than a few hundred metres: the 9/125 µm fibre used by carriers and campus backbones carries the signal for kilometres with little loss. Before you order, confirm the fibre is single-mode at both ends and note the length and the number of patch panels on the way.
