Description

CQP‑31100G‑LR4 Product Overview

The CQP‑31100G‑LR4 is a high-performance, hot‑pluggable QSFP28 optical transceiver module designed for 100GBASE‑LR4 Ethernet applications. It employs four wavelength‑division multiplexed (LWDM) channels operating at 1295.56 nm, 1300.05 nm, 1304.58 nm, and 1309.14 nm, enabling a total aggregate data rate of up to 103.125 Gbps for long‑reach single‑mode fiber transmission.

This module is purpose‑built for medium‑to‑long distance interconnects in data centers, campus backbones, metro access networks, and enterprise core routing. With its high reliability, low power consumption, and full industry compliance, it ensures stable long‑distance transmission up to 10 km over single‑mode fiber (SMF). The compact QSFP28 form factor supports high‑density port deployment while maintaining excellent interoperability with major brand switches, routers, and network equipment.

Key Features

  • High‑Speed 100G Long‑Reach Transmission: 4 × 25.78125 Gbps WDM channels, supporting 100GBASE‑LR4 and aggregate bandwidth up to 103.125 Gbps.
  • Long‑Distance Connectivity: Supports transmission distances up to 10 km over 9/125 μm single‑mode fiber.
  • LWDM Optical Technology: Uses four distributed feedback (DFB) lasers and PIN receivers for stable long‑haul performance.
  • Industry‑Standard Compliance: Fully compliant with IEEE 802.3bm, QSFP28 MSA, SFF‑8665, SFF‑8472, and RoHS‑6 standards.
  • Built‑in Digital Diagnostic Monitoring (DDM): Real‑time monitoring of temperature, voltage, Tx/Rx power, and bias current for intelligent network management.
  • Low Power Consumption: Optimized power design for energy efficiency in high‑density environments.
  • Hot‑Pluggable QSFP28 Package: Easy installation and replacement without system power down.
  • LC Duplex Optical Interface: Standard duplex LC connector for convenient fiber deployment.
  • Wide Operating Temperature Range: Commercial (0°C to 70°C) and industrial (-40°C to 85°C) versions available.

Typical Applications

  • 100GBASE‑LR4 Ethernet networks
  • Data center interconnection (DCI) up to 10 km
  • Campus and enterprise core network uplinks
  • Metro Ethernet and access network transmission
  • Cloud platform long‑distance interconnection
  • Carrier‑grade 100G transport links
  • High‑performance router and switch uplinks
