Product Description

Cisco Compatible 1000BASE-EX 1550nm SMF 40km DOM Duplex LC SFP Transceiver Module





The GIGAOPTO's GTS-L1512-40DC transceiver module is equipped with an LC duplex connector, which is high-performance, cost-effective, supporting data rate of 1.25Gbps at the link distance up to 40km over single-mode fiber (SMF). Featuring low power consumption, the hot swappable 1000BASE-EX SFP transceiver is ideal for Internet Service Provider (ISP) Gigabit Ethernet communication links, Enterprise LAN & SAN Networks, Data Center LAN & SAN Networks and other optical links. This fiber optic transceiver consists of three sections: a DFB laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA), and an MCU control unit. The SFP series are designed to be compliant with SFF-8472 SFP Multi-Source Agreement (MSA).
