1000BASE-SX LC SFP transceiver standard was developed to support lower cost multimode fiber runs in horizontal and shorter-length backbone applications. The LC SFP LX transceiver is for singlemode fiber cables up to 10km, and it also supports the multimode. LX Transceiverġ000BASE-SX SFP LC transceiver is for multimode fiber cables for less than 550 meters. SC is generally used with GBIC, LC is used with SFP transceiver. Moreover, the LC is the “younger” connector of the two, SC is wider spread around the world but LC is catching up. And SC is a true “push-pull-connector” and LC is a “latched connector”, although there are very innovative, real “push-pull-LCs” available which have the same handling capabilities like SC. LC and SC are two different connectors, and they are different in size, handing and history of connector. The main difference between SFP LC and SFP SC transceiver lies in connectors. 1000BASE-SX SFP is designed for transmission within near area, while LC SFP LX transceiver for long-haul transmission. Different protocols have varied requirement for transmission medium, operation temperature, supporting DOM or not, and etc.
LC SFP transceiver means 1000BASE SFP transceiver with LC connectors, which includes 1000BASE-SX SFP, 1000BASE-MX SFP, 1000BASE-LX SFP, 1000BASE-EX SFP, 1000BASE-ZX SFP, 1000BASE-EZX SFP, 1000BASE-BX SFP and CWDM/DWDM SFP transceiver modules.
Knowledge of difference between SFP LC SX and SFP LC LX transceiver would be covered. 1000BASE-SX SFP and 1000BASE-LX SFP transceivers are two different types of 1000BASE SFP LC transceivers. They can be interfaced with different connectors, such as LC, SC, ST, FC, etc. They provide a full range of 1000BASE SFP transceivers types to meet the different requirement for varied transmission distance based on singlemode or multimode fiber.
1000BASE SFP transceivers have been widely used in 1G Ethernet, telecommunication and other applications.
