The 10Gbps Bi-Directional XFP Transceiver is a high-performance module designed for medium-range data communication over single-mode fiber (SMF) up to 20 kilometers. It supports data rates ranging from 9.95Gbps to 11.3Gbps, making it suitable for applications such as 10GBASE-BX Ethernet, SONET OC-192/SDH STM-I64.1, and other high-speed communication systems. This transceiver integrates a 1270nm DFB laser and PIN receiver (CT-XFP-BX-20U) or a 1330nm DFB laser and PIN receiver (CT-XFP-BX-20D) for robust performance. Housed in a hot-pluggable XFP form factor with an LC connector, it complies with XFP Multi-Source Agreement (MSA) and IEEE 802.3ae standards.
Operating on a single +3.3V power supply with power dissipation below 2W, the transceiver is energy-efficient. It functions within a case operating temperature range of 0°C to 70°C, suitable for commercial environments. The module’s advanced design includes a two-wire interface for integrated digital diagnostic monitoring (DDM), providing real-time insights into key parameters like temperature, voltage, bias current, and optical power.
Optically, the transmitter offers an average output power of -5dBm to 0dBm, with an extinction ratio of 3.5dB and compliance with IEEE 802.3ae eye mask requirements. The receiver sensitivity is rated at -15dBm, with an overload threshold of 0.5dBm. The LOS (Loss of Signal) feature provides reliable link monitoring, with assert and deassert thresholds of -30dBm and -18dBm, respectively.
Electrically, the transceiver features a differential impedance of 100Ω, supporting input swing differentials from 120mV to 820mV. It includes functionality for Transmitter Disable (TX Disable) and Fault Indicators, offering precise control and fault management. The module also supports serial EEPROM for device identification and diagnostics, accessible via the 2-wire serial interface.
In summary, the 10Gbps Bi-Directional XFP Transceiver is a robust and versatile solution for high-speed optical communication over medium distances. Its compliance with industry standards, advanced diagnostic capabilities, and efficient design make it an essential component for modern networking and telecommunications systems.
These hot-pluggable 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: BX-20U transmits at 1270 nm and receives at 1330 nm, while BX-20D transmits at 1330 nm and receives at 1270 nm. Designed for 20 km reach, they feature DDMI for real-time monitoring of temperature, bias, Tx/Rx power, and supply voltage. Power dissipation is <1.5 W with a 3.3 V supply, and industrial-grade operation is supported from −40 °C to +85 °C.
