HPE JG661A 40G QSFP+ LC LR4 SM Transceiver Module

Detailed Specifications

The HPE JG661A is a high-performance, hot-pluggable QSFP+ optical transceiver designed for 40 Gigabit Ethernet connectivity in demanding enterprise and data center environments. It addresses the need for reliable, long-distance data transmission, enabling the extension of high-bandwidth links between core switches, routers, and other backbone infrastructure over significant distances. This module is specifically engineered for aggregation and core networking layers where both speed and reach are critical operational requirements. At its core, this transceiver utilizes four Coarse Wavelength Division Multiplexing (CWDM) lanes to achieve an aggregate data rate of 40 Gbps. It operates over standard single-mode fiber (SMF), compliant with the IEEE 802.3ba 40GBASE-LR4 standard, allowing for a maximum transmission distance of up to 10 kilometers. This capability provides network architects with the flexibility to connect buildings across a campus or link distributed data center halls without signal degradation. Physically, the JG661A module conforms to the QSFP+ Multi-Source Agreement (MSA) form factor for broad compatibility with compliant network hardware. It features a standard duplex LC connector for straightforward integration with existing single-mode fiber optic cabling infrastructure. The inclusion of Digital Optical Monitoring (DOM) allows administrators to access real-time operating parameters for proactive network management and troubleshooting.
