Modulo ricetrasmettitore ottico 1000BASE-BX-D CSFP a 2 canali BiDi 1490nm-TX/1310nm-RX 20km DOM Duplex LC/UPC SMF

The 1.25Gbps 1310/1490nm Compact SFP (CSFP) Transceiver is a high-performance optical module designed for bi-directional data communication over single-mode fiber (SMF) up to 20 kilometers. Encased in a compact SFP form factor with an LC/UPC optical interface, it supports data rates of up to 1250Mbps and complies with the 1000Base-BX20 IEEE802.3ah standard. The module integrates a 1310nm FP laser for upstream transmission, a 1490nm DFB laser for downstream transmission, and a PIN photodetector for reliable performance. Its compliance with CSFP MSA and SFF-8472 standards ensures broad compatibility across networking equipment.

Operating on a single +3.3V power supply, the transceiver is energy-efficient with a power consumption of less than 1.5W. It is designed for commercial applications with a case operating temperature range of 0°C to 70°C. The module’s metal enclosure minimizes electromagnetic interference (EMI), ensuring stable and reliable operation in high-performance networks. RoHS compliance further underscores its environmentally responsible design.

The transceiver’s optical performance is optimized for reliability. The transmitter provides an average output power between -9dBm and -3dBm, with an extinction ratio of 8.2dB. The receiver sensitivity is rated at -19dBm, and the module includes advanced diagnostic features such as Loss of Signal (LOS) detection. The LOS output indicates link status or insufficient optical power, enhancing monitoring capabilities for operational stability.

Electrically, the module features a differential impedance of 100Ω and supports input and output swing differentials to facilitate integration with host systems. Digital diagnostics are accessible via a 2-wire serial interface, providing real-time insights into parameters like temperature, voltage, bias current, and optical power. Alarm and warning thresholds alert users to deviations from optimal operating conditions, ensuring reliability and performance.

In summary, the 1.25Gbps 1310/1490nm Compact SFP Transceiver is a robust and efficient solution for short to medium-range bi-directional optical communication. Its advanced optical and electrical capabilities, combined with compliance to industry standards, make it a valuable component for modern networking and telecommunications infrastructure.

This CSFP transceiver delivers 1.25 Gbps bidirectional links over up to 20 km of 9/125 µm single-mode fiber. It complies with CSFP MSA Option 2, IEEE 802.3ah 1000BASE-BX20, e SFF-8472, providing two independent bidirectional optical channels (Ch A and Ch B). The 20U version uses a 1310 nm FP laser for TX and 1490 nm PIN RX, while the 20D version uses a 1490 nm DFB laser for TX and 1310 nm PIN RX. Operating from a 3.3 V supply, it supports real-time digital diagnostic monitoring (DDM) and offers hot-pluggable deployment with LC/UPC interface.
