Product Description

1000BASE-CWDM SFP 100km Transceiver Module 1270-1610nm 1.25Gbps SMF DOM Duplex LC





The GIGAOPTO's GTS-C2712-A0DC series optical transceivers are dual fiber 1000Mbps Small Form-factor Pluggable SFP CWDM modules for use in 1000BASE Ethernet and 1G Fiber Channel.The SFP transceivers are designed to be optically interoperable with IEEE 1000Base-CWDM reaching up to 100km over single-mode fiber (SMF) using an LC duplex connector. All transceivers of this series have been programmed, uniquely serialized and data-traffic and application tested to ensure that it will initialize and perform identically. The optical modules comply with MSA (Multi-Source Agreement) standards to ensure seamless network integration.


Featuring low power consumption, the hot swappable 1G 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.
