TTC-2T18

       TTC-2T18 is a kind of 1*9 fiber optic transceiver for 155 Mbps ATM, SONT OC-3/SDH STM-1 . It has eight unique features: The first one is high quality VCSEL transmitter at 850 nm wavelength. The second one is 50% energy saving over LED transmitters. The third one is low dissipation secures better optical signal after long distance transmission. The forth one is link distance up to 2Km and 4Km with 62.5/125 um and 50/125 um optical fibers respectively.The fifth one is satisfy ATM af-phy-0047.00 specification. The sixth one is meeet IEC 825-1 eye safety standard. The seventh one is industrial standard 1*9 package footprint. The eighth one is duplex ST ports.
