Optical modules CiscoВ serve to convert an electrical signal into an optical one and to transmit and receive data over a fiber optic line. Most optical modules are equipped with a receiver and a transmitter. There are many types of opticalВ modules Cisco, with different characteristics, for example. data transfer rate, form factors, operating range.
To transmit an optical signal, they are mainly usedВ MultiModeВ (multimode) fiber orВ SinglemodeВ (single mode) fiber. When transmitting data using two-fiber optical transceivers,В Tx, TransmitterВ (optical emitter) andВ Rx, ReceiverВ (photodetector). Modules using WDM technologyВ WDMВ (Wavelength Division Multiplexing) allow data to be transmitted over a single fiber using different wavelengths while saving fiber. With technologyВ CWDMВ (Coarse Wavelength Division Multiplexing) up to 8 duplex channels can be achieved on a single fiber (the signal is divided in 20nm steps from 1270nm to 1610nm) over long distances up to 160 km.В DWDMВ technology (Dense Wavelength Division Multiplexing) can provide 60 full duplex channels.
SFPВ В moduleВ CiscoВ transmit data at a speedВ 100 MbВ orВ 1Gb, thanks to the compact size, it is possible to increase the density of ports up to 52 pieces in one unit.В SFP+В modules do not differ in size from SFP modules, and can transfer data 10 times faster (10Gb).В XFP moduleВ slightly different in size fromВ SFP, and used for long distance transmission.В QSFPВ andВ CFPВ are larger and can operate at speedsВ 40GbВ andВ 100Gb.
Various types of connectors can be used to connect to an optical line.:В SCВ Type is used in atrocular modules,В LCВ The type is used in two-wheeled and can also be applied in atomocular modules..
Most optical modules support the functionВ DDMВ (Digital Diagnostics Monitoring). This digital control function of optical transceiver performance parameters allows you to monitor voltage, module temperature, signal levels and other parameters in real time..
