Product Description

Cisco Compatible SFP 1000BASE-SX 850nm MMF 550m DOM Duplex LC Module





The GIGAOPTO's GTS-L0812-02DC transceiver is a cost-effective small form factor pluggable (SFP) with the speed rate up to 1.25Gbps and transmission distance up to 550m using a wavelength of 850nm via an LC connector. This SFP SX module, designed for multi-mode fiber, is a compact, hot-pluggable optical transceiver used for both telecommunication and data communications applications. This transceiver is  compatible with the IEEE 802.3z 1000BASE-SX standard, operating on legacy 50μm multimode fiber links up to 550m and on 62.5μm Fiber Distributed Data Interface (FDDI)-grade multimode fibers up to 220m.
