What Is the Fiber Optic Transceiver?

Fiber optic transceiver is only used for the photoelectric signal conversion, protocol converter is a physical layer device used to convert one protocol to another fiber optic transceivers, fiber broadband converts the twisted pair equipment, 10/100/1000M conversion. Protocol converter, the majority is basically a 2 layer devices, often ran into a protocol converter RAD 2M E1 line convert V.35 data lines connected to the router device, of course there are, 2M turn twisted pair Ethernet, with 2M communication lines can achieve a range of LAN remote access and expand. Maintenance of this equipment it is not generally not bad, as long as it does not burn.

What Is the Optical Multiplexer?

The Optical Multiplexer is divided into the optical transmitter and off receiver, the optical transmitter is to receive the electrical signal, converts the optical signal transmitted in the optical fiber access, while the optical receive the machine. Network video server is to accept analog audio and video signals, cameras and monitor head directly to the signal after digital compression encoding, the popular MPEG-4, dedicated network transmission equipment, video servers generally come with Ethernet RJ-45 interface and fiber FC interface with SCSI interface external hard drive for front- end storage, it is the phrasebook remote network monitoring system in the best equipment. The role of the digital optical multiplexer is to digitize the image, voice and data signals to be transmitted, then the processing of these digital signals multiplexed, multi-channel low-speed digital signals are converted into the way high-speed signal, and this signal is converted into an optical signal. At the receiving end to restore the optical signal into an electrical signal, the high-speed signal, and finally restore the data signals into an image, voice and data signals.

The Difference Between the Fiber Optic Transceiver And Optical Multiplexer

The fiber optic transceivers and optical multiplexer similarities are to perform photoelectric conversion; While they are different in that the fiber optic transceivers primarily pass newtork, only to perform photoelectric conversion, without changing the encoded data is not used for other processing, and the transceiver is for Ethernet network, running 802.3 protocol, only for point-to-point connection. Optical multiplexer in addition to the photoelectric conversion, but also the data signal multiplexing and demultiplexing, a core transmission of video, 485/422 / audio / ON light quantity / network, usually Optical Multiplexer out a plurality of pairs of E1 lines. Fibre transceiver applications such as banking, education, networking. While, SDH, PDH optical multiplexer mainly for telecom operators to provide more point-to-point data circuits; The Video optical multiplexer is mainly for security monitoring, the timeliness field of distance education, video conferencing, video transmission requirements, at the same time control, switching, voice, Ethernet can transmit signals to meet the needs of more service applications, so we sometimes also referred to as integrated optical multiplexer.
