SFP Optical Transceiver Module for Data Transmission - RSM155W56S120

Optical transceiver modules of SFP form factor (SFP modules or SFP transceivers for short) are widely used in fibre-optic communication lines (FOCL) for receiving and transmitting data between various communication devices: switches, routers, multiplexers and other network equipment. SFP modules provide conversion of the electrical signal from the network equipment into optical signals of a given wavelength and power, for its transmission over the FOCL, and the reverse conversion at the reception. SFP module is a printed circuit board in a compact metal case, equipped with a snap for reliable fixation of SFP module inside the communication equipment. Technical parameters of the module RSM155W56S120: Form factor - SFP; Data rate - 155 Mbps; Number of optical fibres - 1; Transmitter wavelength - 1490 nm; Receiver wavelength - 1550 nm; Communication range - 120 km; Type of optical connector - SC.
