Amer Networks MGBS-GLX70 mini-GBIC 1250Mbit/s Single-mode network transceiver module

1 port mini GBIC ZX Single-Mode Fiber Transceiver, 70km, 3.3V The MGBS-GLX70 is a high performance 1550nm singlemode SFP/mini-GBIC transceiver supporting full duplex, gigabit speeds on multimode and singlemode fiber for distances of up to 70km on 9µ fiber respectively. This hot pluggable unit has a metal housing to reduce EMI and to increase durability. The industry standard MGBS-GLX70 Gigabit Interface Converter (SFP/mini-GBIC) operates on ordinary single-mode fiber optic link spans up to 43.4 miles (70 km) long. Link spans of up to 62 miles (100 km) are possible using premium single-mode fiber or dispersion shifted single-mode fiber. The SFP/mini-GBIC provides an optical link budget of 23 dB—the precise link span length will depend on multiple factors such as fiber quality, number of splices, and connectors. When shorter distances of single-mode fiber are used, it might be necessary to insert an in-line optical attenuator in the link to avoid overloading the receiver. A 5-dB or 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the MGBS-GLX70 SFP/mini-GBIC at each end of the link whenever the fiber-optic cable span is less than 15.5 miles (25 km), or consider an alternative such as the MGBS-GLX40.
