Product Description

Cisco Compatible BIDI SFP 1000BASE-BX 1490nm-TX/1310nm-RX 10km SMF 1.25Gbps DOM Simplex LC Transceiver Module
The GIGAOPTO's GTS-B4312-10DC transceiver provides 1000Base-BX throughput up to 10km over single-mode fiber (SMF) using a wavelength of 1490nmTx/1310nmRx via an LC connector. It meets the Small Form Pluggable (SFP) industry standard package utilizing an integral LC-Bi-directional optical interface connector. This SFP Module also supports Digital Optical Monitoring (DOM) functions according to the industry-standard SFF-8472 Multisource Agreement (MSA).
The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the 1310nm FP laser (the 1490nm DFB laser)and the PIN/TIA. The module data links up to 10km in 9/125um Single-mode fiber. The SFP transceiver module is a Class 1 laser product that complies with FDA/CDRH and IEC-60825 standards.
