Product Description

Cisco Compatible 1000BASE-BX BiDi SFP 1.25Gbps Transceiver Module 1310nm-TX/1490nm-RX 40km SMF DOM Simplex LC





The GIGAOPTO's GTS-B3412-40DC transceiver is a high performance and cost-effective small form factor pluggable (SFP) Bi-directional transceiver for 1000BASE Gigabit Ethernet and 1G Fiber Channel application. The 1000BASE-BX SFP optical module provides 40km high-speed data links using a single strand of fiber at 1310nm-TX/1490nm-RX wavelengths via LC simplex connectors, making it very easy to upgrade transmission capacity without installing new fiber. The SFP transceiver module is a Class 1 laser product that complies with FDA/CDRH and IEC-60825 standards.


This 1000BASE-BX BiDi SFP 40km transceiver is fully compliant with SFP Multi-Source Agreement (MSA), IEEE 802.3 1000BASE-BX40 and SERDES standard.
