Product Description

Cisco Compatible BiDi SFP 1490nm-TX/1550nm-RX 80km 1.25G 1000BASE-BX SMF Simplex LC DOM Transceiver Module





The GIGAOPTO's GTS-B4512-80DC SFP transceiver operates at 1000BASE-BX with a wavelength of Tx1490nm/Rx1550nm with a maximum reach of 80km over single-mode fiber (SMF) via LC simplex connectors. The transmitter section uses a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses an integrated B type/A type detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.


The 1000BASE-BX BiDi SFP transceiver is designed for single-mode data transmissions with 1.25G in optical fiber networks. It supports Ethernet and Fibre Channel applications in switches, routers, storage systems and other related hardware.


All GIGAOPTO’s SFP transceivers are MSA compliant for seamless integration and RoHS compliant for environmental conformity.
