Specifications
The 10Gbps Bi-Directional SFP+ Transceiver is a reliable and high-performance module designed for short-range optical communication over single-mode fiber (SMF) up to 10 kilometers. It supports data rates of up to 11.1Gbps and integrates a 1270nm DFB laser for transmission and a 1330nm PIN receiver for reception, or vice versa, depending on the model. This module is housed in a compact, hot-pluggable SFP+ form factor with an LC connector, ensuring seamless integration with various networking equipment. Fully compliant with SFF-8431, SFF-8472, and IEEE 802.3ae standards, it is ideal for applications like 10GBASE-BX and 10G Ethernet.
Operating on a single +3.3V power supply, the transceiver boasts low power dissipation of less than 1.5W. It is designed for commercial environments with an operating temperature range from 0°C to 70°C, making it suitable for a wide range of applications. Its RoHS compliance and hot-pluggable design facilitate easy upgrades and environmentally friendly deployment.
The optical performance is optimized for reliability, with a launched power range of -6dBm to -1dBm and an extinction ratio of 3.5dB. The receiver sensitivity is rated at -14.4dBm, ensuring robust performance over the specified distance. The module also features advanced monitoring capabilities, including Loss of Signal (LOS) detection, which provides diagnostics for link stability.
Electrically, the transceiver supports a differential input impedance of 100Ω and complies with the SFP+ MSA for interface compatibility. Digital diagnostics monitoring is accessible via a 2-wire serial interface, providing real-time tracking of operating parameters such as temperature, voltage, bias current, transmitted power, and received power. Alarm and warning thresholds ensure operational reliability and facilitate proactive maintenance.
In summary, the 10Gbps Bi-Directional SFP+ Transceiver is a versatile and efficient solution for high-speed optical communication. Its advanced features, compliance with industry standards, and robust design make it an excellent choice for modern data networking and telecommunications infrastructure.
These SFP+ modules support data rates up to 11.1 Gbps and comply with IEEE 802.3ae 10GBASE-LR/LW, SFF-8431, and SFF-8472 standards. They use a simplex LC interface for bi-directional operation: CT-SFP+BX-10U transmits at 1270 nm and receives at 1330 nm, while CT-SFP+BX-10D transmits at 1330 nm and receives at 1270 nm. Optimized for 10 km reach, they integrate digital diagnostics monitoring (DDMI) for real-time performance tracking. Power dissipation is <1.5 W with an operating case temperature range of 0 °C to +70 °C.
