RMC-121FB-SS-SCMedia converter module over single-mode fiber up to 30 km
RMC-121FB-SS-SC carries Ethernet traffic from a copper segment to a single-mode fiber, when the run exceeds the reach of copper or of multimode.
The optical channel works at 1310 nm on an SC connector with a 19 dB link budget; flow control follows IEEE 802.3x, while the Fast Ethernet side refers to IEEE 802.3u. The module weighs 0.137 kg, withstands storage up to 85 °C and is protected against current overload.
