Nokia 3FE48235AA Compatible 10GBASE-BX20-U BiDi SFP+ 1270nm-TX/1330nm-RX 20km DOM Simplex LC/UPC SMF Optical Transceiver Module

The 10Gbps Bi-Directional SFP+ Transceiver is a high-performance module designed for medium-distance optical communication over single-mode fiber (SMF) up to 20 kilometers. Supporting data rates of up to 11.1Gbps, it integrates a 1270nm DFB laser and a PIN receiver for upstream communication (CT-SFP+BX-20U) and a 1330nm DFB laser and PIN receiver for downstream communication (CT-SFP+BX-20D). This transceiver is built in a hot-pluggable SFP+ form factor with an LC connector, making it ideal for applications such as 10GBASE-BX Ethernet. It complies with SFF-8472 and SFF-8431 standards, as well as IEEE 802.3ae, ensuring compatibility with modern network systems.

The module operates on a single +3.3V power supply with a power consumption of less than 1.5W, making it energy-efficient for industrial and commercial applications. Designed to function in challenging environments, it supports an extended case operating temperature range from -40°C to +85°C. RoHS compliance ensures that the product meets environmental standards.

The optical performance of the transceiver is robust. The transmitter provides an average output power ranging from -5.4dBm to -1dBm, with an extinction ratio of 3.5dB for clear signal differentiation. The receiver features a sensitivity of -15dBm and can handle wavelengths from 1260nm to 1280nm for the upstream module and 1320nm to 1340nm for the downstream module. Additional features, such as Loss of Signal (LOS) detection, enhance diagnostic capabilities, allowing real-time monitoring of link conditions.

Electrically, the transceiver includes a differential input impedance of 100Ω and supports input and output swing differentials to ensure compatibility with host systems. The module also integrates advanced digital diagnostics monitoring, accessible via a 2-wire serial interface, to provide real-time feedback on operating parameters such as temperature, voltage, bias current, and optical power. Alarm and warning thresholds notify users of deviations from optimal conditions.

In summary, the 10Gbps Bi-Directional SFP+ Transceiver is a versatile and reliable solution for high-speed networking over medium distances. Its compliance with industry standards, robust diagnostic features, and efficient design make it a critical component for modern telecommunications and data center infrastructures.

These hot-pluggable 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 connector for bi-directional transmission: CT-SFP+BX-20U transmits at 1270 nm and receives at 1330 nm, while CT-SFP+BX-20D transmits at 1330 nm and receives at 1270 nm. Designed for 20 km reach, they include digital diagnostics monitoring (DDMI) for real-time parameter tracking. Power dissipation is <1.5 W, with industrial-grade operating temperature from −40 °C to +85 °C.
