It is suitable for access, enterprise, data center, and telecommunications applications requiring 100Gbps long-reach connectivity. :contentReference[oaicite:1]{index=1}

10KM Single-Mode Fiber Transmission

The transceiver is designed for single-mode fiber (SMF) and supports a maximum transmission distance of 10km. The optical link uses the LAN-WDM wavelength grid to provide high-capacity transmission over the duplex fiber connection.

LAN-WDM Optical Architecture

The four optical channels operate across the 1295nm to 1309nm wavelength range. This multi-channel architecture combines the optical signals for transmission over a single duplex LC fiber pair and supports the requirements of 100GBASE-LR4-class connectivity. :contentReference[oaicite:2]{index=2}

QSFP28 and Duplex LC Interface

The QSFP28 form factor provides a compact, hot-pluggable interface for compatible 100Gbps networking equipment. The module uses a duplex LC connector for single-mode fiber connectivity.

Digital Optical Monitoring

The module supports Digital Optical Monitoring (DOM), allowing compatible host equipment to access supported optical operating information for network monitoring and maintenance. :contentReference[oaicite:3]{index=3}

• 10km single-mode fiber links

Compatibility

The Extreme Networks 10403-OTU4 is designed as a compatible dual-rate QSFP28 transceiver for Extreme Networks equipment supporting 100GBase/OTU4-LR4 optical connectivity. The exact switch, port configuration, software/firmware version, and supported optic list should be verified before installation.

For a 10km deployment, the complete optical link should also be checked for fiber attenuation, connector losses, and available optical budget to ensure reliable operation.
