Front liter QS-3100S-20BM single-mode fiber transceiver Fast liter QS-3100S-20BM mode single fiber bi-directional fiber optic Ethernet transceivers are used to convert electrical signals into optical signals photoelectric signal converter, which is characterized by a pair of (core) optical fiber can simultaneously transmit and receive optical signals, due to the form of light pulses in optical signal is transmitted signals so thousands of copper wires relative to many and advantages: safety, reliability sex, transmission speed, transmission distance is very suitable for local area networks, metropolitan area network, modular design allows for centralized management on the rack. Two-fiber bidirectional transceivers have an RJ45 connector and one SC single interface are used to connect the twisted pair and fiber. Fiber transceiver has six LED indicators: POWER, TX100, FX100, FX Link / Act, TX Link / Act, Fdx. TX: denotes an optical fiber signal transmission interface RX: denotes an optical fiber signal reception interface LAN: RJ45 network interface indicates performance: in line with IEEE802.3u, 100Base-TX and 100Base-FX standards provide a multi-mode SC type fiber ports and one RJ-45 port modular design (available on centralized power rack) multimode fiber transmission distance up to 2KM connection support store and forward mode supports full-duplex / half-duplex mode ports support Auto-MDI / MDIX auto-flip LED lights dynamic feedback loop signals, and fault monitoring of hot-swappable, plug and play mean time between failures provide quality assurance and technical parameters of the standard service life of three years more than 50,000 hours: IEEE802.3u, 10 / 100Base-TX and 100Base -FX work: full / half duplex operating wavelengths: 1310nm Connector: a UTP RJ-45 port, a SC Interface LED indicators: POWER, TX100 TXLink / ACT, FX100 FXLink / ACT, FDX transmission speed : 100Mb / s Ambient temperature: 0-50 ℃ Relative humidity: 5% -90% IP cable Cat.5 UTP Cable fiber optic cable: 50 / 125,62.5 / 125uM Multimode Power Specifications: Input AC: 110-265V output DC: 5V @ 1A ripple ≤50mV Dimensions: 95mm × 71mm × 25mm (external power supply)
