CQP-31100G-LR4: The Standard for 100G Long-Reach Optical Connectivity

1. Summary

The CQP-31100G-LR4 100G QSFP28 LR4 Optical Transceiver is an industry-leading interconnect solution designed to deliver high-performance data transmission over distances up to 10km using Single-Mode Fiber (SMF). In an era where cloud computing and hyperscale data centers demand relentless speed and reliability, this module bridges the gap between high port density and long-distance requirements. Within the first 100 characters, it is evident that the CQP-31100G-LR4 100G QSFP28 LR4 Optical Transceiver serves as the backbone for modern 100GbE enterprise and carrier networks. Operating via LC duplex connectors, it utilizes sophisticated LAN-WDM wavelength division multiplexing to ensure signal integrity across the 1310nm window. This summary encapsulates its role in optimizing spectral efficiency while maintaining a low power profile, making it a "de facto" standard for those seeking to expand their fiber infrastructure without sacrificing thermal efficiency or spectral purity in congested network environments.

2. What: Technical Definition and Core Concepts

The CQP-31100G-LR4 is a 100Gbps Quad Small Form-factor Pluggable 28 (QSFP28) transceiver module compliant with the IEEE 802.3ba 100GBASE-LR4 standard. Unlike short-reach solutions that rely on multi-mode fiber, this module is engineered for long-reach (LR) applications, specifically tailored for 10km spans over standard G.652 Single-Mode Fiber.

Technically, the module converts 4 input channels of 25Gbps electrical data into 4 channels of LAN-WDM optical signals. These signals are multiplexed onto a single fiber via an internal optical multiplexer and then de-multiplexed at the receiving end Pub Time : 2026-05-13 15:11:35 >> News list
