 Product Description: 
 OPT-100T fiber optic transceivers (card type) 
 OPT-100 fiber optic transceivers by the original transmission on the twisted-pair Ethernet electrical signals into the optical fiber to transmit light signals, which greatly extends the Ethernet connection distance. OPT-100 fiber optic transceiver optical interface to meet IEEE802.3u 100Base-FX standards; electrical interfaces to meet the IEEE802.3 10Base-T and IEEE802.3u 100Base-TX standards, support 10/100M, full / half duplex auto-negotiation, flexibility to meet local area network users and network systems integrator of networking needs. OPT-100 fiber optic transceiver based on the different optical transmission medium is divided into multi-mode, single mode dual fiber and single-mode single fiber of three. As the single fiber bi-directional optical transceiver signal using wavelength division multiplexing technology to send and receive wavelengths different wavelength, that wavelength of a device to send 1310nm, receiving wavelength 1550nm, the wavelength of the other device to send 1550nm, 1310nm wavelength receiver , must be paired.
