Specifications
The 10Gbps Bi-Directional XFP Transceiver is a versatile and efficient optical module designed for medium-range data communication over single-mode fiber (SMF) up to 40 kilometers. Supporting data rates from 9.95Gbps to 11.3Gbps, this transceiver is suitable for applications such as 10GBASE-BX Ethernet, SONET OC-192/SDH STM-I64.1, and other high-speed communication systems. The CT-XFP-BX-40U utilizes a 1270nm DFB laser transmitter and a 1330nm PIN receiver, while the CT-XFP-BX-40D includes a 1330nm DFB laser transmitter and a 1270nm PIN receiver. This module complies with the XFP Multi-Source Agreement (MSA) and IEEE 802.3ae standards, making it compatible with modern networking equipment.
This transceiver operates on a single +3.3V power supply with a power consumption of less than 3.5W, ensuring energy efficiency. Designed for commercial environments, it functions within a case operating temperature range of 0°C to 70°C. Its hot-pluggable design and duplex LC connector make it easy to install and upgrade in existing network systems.
The optical performance is robust, with the transmitter offering an output power range of 0dBm to +5dBm and an extinction ratio of 3.5dB, meeting IEEE 802.3ae requirements. The receiver provides a sensitivity of -15dBm and a saturation power of +0.5dBm, ensuring reliable data reception over long distances. The transceiver also features Loss of Signal (LOS) detection for enhanced link monitoring and diagnostics.
Electrically, the module supports a differential impedance of 100Ω and input swing differentials ranging from 120mV to 820mV. Advanced diagnostic capabilities include real-time monitoring of operating parameters such as temperature, voltage, bias current, transmitted optical power, and received optical power. These diagnostics are accessible via a two-wire serial interface and include alarm and warning thresholds for proactive network management.
In summary, the 10Gbps Bi-Directional XFP Transceiver is a dependable solution for medium-range optical communication. Its compliance with industry standards, advanced diagnostics, and robust design make it an essential component for modern telecommunications and data networking infrastructures.
These hot-pluggable SFP+ modules support data rates up to 11.1 Gbps and comply with IEEE 802.3ae 10GBASE-ER/EW, SFF-8431, and SFF-8472 standards. They use a simplex LC connector: BX-40U transmits at 1270 nm and receives at 1330 nm, while BX-40D transmits at 1330 nm and receives at 1270 nm. Designed for 40 km reach, the modules feature DFB lasers, PIN receivers, and digital diagnostics monitoring (DDMI). Power consumption is <1.5 W, with a single 3.3 V supply and commercial operating case temperature from 0 °C to +70 °C.
