Specifiche tecniche
The 10Gbps Bi-Directional SFP+ Optical Transceiver is a high-performance module designed for medium-range data communication over single-mode fiber (SMF) up to 40 kilometers. This module supports data rates of up to 11.1Gbps and incorporates a DFB laser and PIN receiver. The CT-SFP+BX-40U features a 1270nm transmitter and a 1330nm receiver, while the CT-SFP+BX-40D includes a 1330nm transmitter and a 1270nm receiver. Encased in a compact, hot-pluggable SFP+ form factor with an LC connector, it is compliant with industry standards such as SFF-8472, SFF-8431, and IEEE 802.3ae, making it suitable for 10GBASE-BX and 10G Ethernet applications.
Operating on a single +3.3V power supply, the module offers a power consumption of less than 1.5W, ensuring energy efficiency. It functions reliably within a case operating temperature range of 0°C to +70°C and complies with RoHS regulations for environmentally responsible design. Its integrated digital diagnostic monitoring allows for real-time access to operational parameters, enhancing performance management.
Optically, the transmitter provides an average output power range of 0dBm to +5dBm and an extinction ratio of 3.5dB, ensuring robust signal transmission. The receiver operates with a sensitivity of -15dBm and an overload threshold of 0.5dBm, supporting stable performance in varying conditions. Additional features include Loss of Signal (LOS) detection, which aids in diagnostics and link stability.
Electrically, the transceiver supports a differential impedance of 100Ω, with input swing differentials from 180mV to 700mV. It provides advanced functionality such as Transmitter Disable and Fault Indicators to enable precise control and fault management. The two-wire serial interface allows easy access to diagnostic data, ensuring proactive maintenance and network reliability.
In summary, the 10Gbps Bi-Directional SFP+ Optical Transceiver is a reliable and efficient solution for high-speed optical communication over medium distances. Its adherence to international standards, advanced optical and electrical performance, and diagnostic capabilities make it a valuable component for modern data networking and telecommunications systems.
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 interface for bi-directional operation: CT-SFP+BX-40U transmits at 1270 nm and receives at 1330 nm, while CT-SFP+BX-40D transmits at 1330 nm and receives at 1270 nm. Optimized for 40 km reach, they integrate digital diagnostics monitoring (DDMI) for real-time performance tracking. Power dissipation is <1.5 W with an operating case temperature of 0 °C to +70 °C.
