HPE JD112A Compatible SFP 1000BASE-CWDM 1270nm-1610nm 80km DOM Duplex LC/UPC SMF Optical Transceiver Module for Transmission

The 1.25Gbps CWDM Single-mode SFP Transceiver is a versatile and efficient optical module designed for long-distance data communication over single-mode fiber (SMF) up to 80 kilometers. Encased in a hot-pluggable SFP footprint with a duplex LC/UPC optical interface, it incorporates a DFB laser transmitter and PIN photo-detector for reliable performance. This transceiver supports data rates of up to 1.25Gbps, making it ideal for applications such as switch-to-switch interfaces, Gigabit Ethernet, backplane connections, router/server interfaces, and other optical links. It is compliant with SFF-8472 standards, ensuring compatibility with modern networking equipment.

The transceiver operates with a single +3.3V power supply and features low power dissipation. Its metal enclosure minimizes electromagnetic interference (EMI), ensuring stable and reliable operation in demanding environments. Designed for commercial applications, it operates within a temperature range of 0°C to +70°C. Furthermore, its compliance with RoHS regulations highlights its environmentally friendly design.

The optical performance of the transceiver is notable, with a transmitter average output power range of 0dBm to +5dBm and an extinction ratio of 9dB. It supports CWDM wavelengths ranging from 1270nm to 1610nm, allowing for efficient channel allocation and bandwidth usage. The receiver is highly sensitive, with a minimum sensitivity of -26dBm and the ability to handle input wavelengths from 1270nm to 1610nm. Advanced diagnostic features such as Loss of Signal (LOS) and Transmitter Disable (Tx Disable) provide enhanced operational control and monitoring.

In terms of electrical performance, the transceiver features a differential line input impedance of 100Ω and complies with IEEE 802.3z standards for transmitter output eye masks. Its 2-wire serial communication protocol enables access to identification and diagnostic information. The module also supports real-time monitoring of operating parameters such as temperature, optical power, and supply voltage, with alarm and warning flags to alert users when conditions deviate from normal ranges.

In summary, the 1.25Gbps CWDM Single-mode SFP Transceiver is a robust, energy-efficient solution for medium-range networking applications. Its advanced features, combined with adherence to industry standards, make it a dependable choice for modern telecommunications and high-performance data infrastructures.

This CWDM SFP module supports flexible wavelength allocation across the 1270–1610 nm range, enabling efficient use of fiber infrastructure. It uses a DFB laser and PIN-TIA receiver combination, supports a +3.3 V power supply, and has a compact hot-pluggable design. With low power consumption, EMI shielding, and RoHS compliance, it is well-suited for metro and regional optical transport.
