Especificaciones
The 10Gbps Bi-Directional XFP Transceiver is a high-performance module designed for long-range optical communication over single-mode fiber (SMF) up to 80 kilometers. It supports data rates from 9.95Gbps to 11.3Gbps, making it suitable for 10GBASE-BX Ethernet and SONET OC-192/SDH STM-64 applications. This transceiver is available in two configurations: the CT-XFP-BX-80U with a 1490nm EML laser transmitter and a 1550nm APD receiver, and the CT-XFP-BX-80D with a 1550nm EML laser transmitter and a 1490nm APD receiver. The module complies with XFP Multi-Source Agreement (MSA) standards, ensuring seamless integration with existing networking systems.
The transceiver operates on a single +3.3V power supply, with power dissipation of less than 2.5W, making it an energy-efficient choice. It is designed for both commercial and industrial applications, with case operating temperature ranges of -10°C to 70°C for commercial use and -40°C to 85°C for industrial environments. The hot-pluggable design and duplex LC connector ensure ease of deployment and high-density networking capabilities.
Optical performance includes a transmitter output power of 0dBm to +4dBm for the CT-XFP-BX-80U and -1dBm to +3dBm for the CT-XFP-BX-80D, with an extinction ratio of 6dB. The receiver sensitivity is rated at -24dBm, with a saturation power of -6dBm, providing robust performance over extended distances. Additional features such as Loss of Signal (LOS) detection enhance 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 temperature, voltage, bias current, transmitted optical power, and received optical power, accessible via a 2-wire serial interface. Alarm and warning flags enable proactive maintenance and reliability assurance.
In summary, the 10Gbps Bi-Directional XFP Transceiver is a reliable and efficient solution for high-speed optical communication over extended distances. 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, SFF-8431, and SFF-8472 standards. They use a simplex LC interface: CT-SFP+BX-80U transmits at 1490 nm and receives at 1550 nm, while CT-SFP+BX-80D transmits at 1550 nm and receives at 1490 nm. Designed for up to 80 km reach, the modules integrate an APD receiver and support digital diagnostics monitoring (DDMI) via a 2-wire interface. Power dissipation is typically <1.5 W, with operating case temperature ranges of –10 °C to +70 °C (commercial) and –40 °C to +85 °C (industrial).
