Product Description

Cisco Compatible 1550nm 120km 1000BASE-EZX SMF DOM Duplex LC SFP Transceiver Module





The GIGAOPTO's GTS-L1512-C0DC transceiver is a high performance, cost effective module supporting data rate of 1.25Gbps and 120km transmission distance with LC duplex single-mode fiber (SMF). The transceiver consists of three sections: a DFB laser transmitter, a APD photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. This module is built to operate at a nominal wavelength of 1550nm for serial optical data communications such as Gigabit Ethernet 1000BASE-ZX and Fiber Channel 1x SM-LC-L FC-PI. All modules meet international class I laser safety standards.
