Huawei QSFP-40G-eSR4-0.15KM (Part Number: 02310RMB)

Detailed Product Overview

The Huawei QSFP-40G-eSR4 (02310RMB) is a specialized, short-reach optical transceiver module. It is compliant with the QSFP+ Multi-Source Agreement (MSA) and the 40GBASE-eSR4 (Enhanced Short Reach) standard, specifically optimized for high-density 40 Gigabit Ethernet links in data center and enterprise environments.

Key Technical Features

• Form Factor and Rate: It is a hot-pluggable QSFP+ module supporting an aggregate data rate of 40 Gbps (4×10 Gbps lanes).

• Wavelength and Media: The module operates at a center wavelength of 850 nm using VCSEL laser technology over Multi-Mode Fiber (MMF).

• Maximum Reach: Maximum transmission distance depends on the MMF type used:

  • 300 meters (0.3 km) over OM3 fiber.

  • 400 meters (0.4 km) over OM4 fiber.

• Connector Type: It uses an MPO/PC connector (8-strand or 12-strand, type B, female connector) for parallel optical signaling.

• Breakout Support: A key feature is its ability to connect one 40GE port to four 10GE ports using a 1-to-4 breakout cable, allowing for flexible architecture design.

• Optical Characteristics (Per Lane):

  • Minimum Transmit Power: -7.6 dBm.

  • Maximum Transmit Power: +0.5 dBm.

  • Receiver Sensitivity (Average): -5.4 dBm (or $\approx -11.1$ dBm for some variations).

• Monitoring and Power: The module supports Digital Diagnostic Monitoring (DDM) for temperature and voltage and operates within a commercial case temperature range of $0^\circ\text{C}$ to $70^\circ\text{C}$.

• Application: It is commonly used in Huawei CloudEngine 8800, 7800, 6800, and 5800 Series Switches.
