The 10Gbps Bi-Directional SFP+ Transceiver is a high-performance module designed for long-distance data communication over single-mode fiber (SMF) up to 80 kilometers. Supporting data rates of up to 11.1Gbps, the CT-SFP+BX-80U features a 1490nm EML laser transmitter and an APD receiver operating at 1550nm, while the CT-SFP+BX-80D integrates a 1550nm EML laser transmitter and a 1490nm APD receiver. This hot-pluggable SFP+ module includes a duplex LC connector and complies with SFF-8431, SFF-8472, and IEEE 802.3ae standards, ensuring compatibility with industry-standard equipment for 10GBASE-BX applications.
The transceiver is designed for efficient and reliable operation, consuming less than 1.5W of power and functioning within a commercial temperature range of -10°C to 70°C, or an extended industrial range of -40°C to 85°C. RoHS compliance ensures an environmentally friendly design. Integrated digital diagnostic monitoring (DDM) provides real-time feedback on operational parameters, facilitating proactive network management.
Optically, the transceiver delivers an average output power of 0dBm to +4dBm for the upstream unit and -1dBm to +3dBm for the downstream unit, with an extinction ratio of 7.5dB. The receiver sensitivity is rated at -23dBm, with a saturation power of -6dBm. Advanced diagnostic features include Loss of Signal (LOS) functionality to monitor link stability and signal quality.
Electrically, the transceiver supports a differential impedance of 100Ω, with input swing differentials between 180mV and 1200mV. Output swing differentials range from 300mV to 850mV, ensuring compatibility with diverse host systems. Transmitter Disable (TX Disable) and Fault Indicators enhance control and fault management. The module’s diagnostics adhere to the SFF-8472 standard, offering critical insights into temperature, voltage, bias current, transmitted optical power, and received optical power.
In summary, the 10Gbps Bi-Directional SFP+ Transceiver is a reliable, energy-efficient solution for high-speed, long-distance networking. Its compliance with industry standards, robust diagnostic capabilities, and advanced optical and electrical performance make it a key component for modern telecommunications and data communication infrastructures.
These hot-pluggable XFP modules operate from 9.95 to 11.3 Gbps and comply with the XFP MSA standard. They support single-fiber bidirectional links using LC connectors: CT-XFP-BX-80U transmits at 1490 nm and receives at 1550 nm, while CT-XFP-BX-80D transmits at 1550 nm and receives at 1490 nm. Designed for up to 80 km reach, they feature digital diagnostics monitoring per XFP MSA. Power consumption is <2.5 W, with options for commercial (−10 °C to +70 °C) or industrial (−40 °C to +85 °C) operating ranges.
