Specifications
The 10Gbps Bi-Directional XFP Transceiver is designed for high-speed data communication over single-mode fiber (SMF) up to 60 kilometers. Supporting bit rates from 9.95Gbps to 11.3Gbps, the CT-XFP-BX-60U features a 1270nm DFB laser transmitter and an APD receiver at 1330nm, while the CT-XFP-BX-60D includes a 1330nm DFB laser transmitter and an APD receiver at 1270nm. This transceiver complies with XFP MSA standards and is ideal for applications like 10GBASE-BX Ethernet and SONET OC-192/SDH STM I-64.1.
Operating on a +3.3V power supply with a power consumption of less than 3.5W, the module offers energy-efficient performance. It operates within a temperature range of 0°C to 70°C for commercial use and features hot-pluggable functionality for easy installation and integration. The transceiver also supports a two-wire interface for real-time digital diagnostic monitoring, providing operational insights into key parameters such as temperature, voltage, and optical power.
Optically, the transceiver delivers an output power of 0dBm to +5dBm with an extinction ratio of 3.5dB, ensuring reliable signal transmission. The receiver sensitivity is -22dBm, with a saturation power of -6dBm. Advanced features like Loss of Signal (LOS) detection provide enhanced link diagnostics, with LOS assert and deassert thresholds set for optimal monitoring and performance reliability.
Electrically, the module supports a differential impedance of 100Ω and input/output swing differentials ranging from 120mV to 850mV. The inclusion of Transmitter Disable (TX Disable) and Fault Indicators allows for precise control and fault management. Alarm and warning flags further enhance operational reliability by alerting users to deviations from optimal performance.
In summary, the 10Gbps Bi-Directional XFP Transceiver is a robust and efficient solution for medium to long-distance networking applications. Its advanced optical and electrical features, compliance with industry standards, and real-time monitoring capabilities make it a valuable component in modern telecommunications and data networking infrastructures.
These hot-pluggable SFP+ modules support data rates up to 11.1 Gbps and are compliant with IEEE 802.3ae, SFF-8431, and SFF-8472 standards. They use a simplex LC connector for bidirectional transmission: BX-60U transmits at 1270 nm and receives at 1330 nm, while BX-60D transmits at 1330 nm and receives at 1270 nm. Designed for 60 km reach, they feature a DFB laser, APD receiver, and DDMI for real-time monitoring. Power dissipation is <1.5 W, supplied by a single 3.3 V rail, with an operating case temperature of −5 °C to +70 °C.
