10GBASE-BX10-D BiDi SFP+ 1330nm-TX/1270nm-RX 3km DOM Simplex LC/UPC SMF Optical Transceiver Module

The 1.25Gbps Bi-Directional SFP Optical Transceiver is a high-performance module designed for short-range data communication over single-mode fiber (SMF) up to 3 kilometers. Featuring a 1310nm FP laser and 1550nm PIN photodetector for the upstream module (CT-SFP-BX-3U) and a 1550nm FP laser with a 1310nm PIN photodetector for the downstream module (CT-SFP-BX-3D), this transceiver ensures robust performance for Ethernet, telecom, and Fiber Channel applications. It is housed in a compact SFP form factor with an LC connector, making it an efficient and versatile solution for modern networks.

The transceiver operates on a single +3.3V power supply, with low power dissipation capped at 1W. Designed for both commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges, it provides reliable operation in diverse environments. It is compliant with IEC-60825 laser safety standards and RoHS regulations, ensuring safety and environmental sustainability.

Optical performance is a key feature of this module. The transmitter provides a center wavelength of 1310nm for the upstream module and 1550nm for the downstream module, with an average output power range of -12dBm to -6dBm and an extinction ratio between 9dB and 15dB. The receiver section offers a sensitivity of -24dBm and an overload threshold of -3dBm. Additional diagnostic features like Loss of Signal (LOS) detection ensure link stability and monitoring capabilities.

The transceiver’s electrical design supports a differential impedance of 100Ω and an input swing differential of 500mV to 2400mV. It includes advanced features such as TX Disable and TX Fault for enhanced control and fault management. The module is fully compliant with IEEE 802.3z and ANSI Fiber Channel standards, ensuring compatibility with existing networking infrastructure.

In summary, the 1.25Gbps Bi-Directional SFP Optical Transceiver is an efficient and reliable solution for high-speed, short-distance networking. Its compliance with industry standards, robust optical and electrical specifications, and environmentally friendly design make it a valuable component for modern telecommunications and data communication systems.

These SFP modules support Fast/Gigabit data rates up to 1.25 Gbps and are fully compliant with SFP MSA standards. They operate over a single simplex LC interface, with CT-SFP-BX-3U transmitting at 1310 nm and receiving at 1550 nm, while CT-SFP-BX-3D transmits at 1550 nm and receives at 1310 nm. Designed for short single-mode fiber spans up to 3 km, the modules use a single +3.3 V power supply, dissipate <1 W, and are available in commercial (0 °C to +70 °C) and industrial (−40 °C to +85 °C) grades. They feature LVPECL-compatible I/O, excellent EMI/ESD resistance, and comply with IEC 60825 Class 1 laser safety and RoHS.
