100Gb/s High-Speed Networking

The FTLC9559REPM is designed for 100 Gigabit Ethernet applications, providing an aggregate data rate of up to 103.1Gb/s at the optical module level. The module uses four optical channels operating at 25Gb/s each to provide high-bandwidth network connectivity. :contentReference[oaicite:3]{index=3}

This makes it suitable for high-density switching environments, server aggregation, data center uplinks and other applications requiring 100GbE connectivity.

100GBASE-SR4 Optical Standard

The FTLC9559REPM supports 100GBASE-SR4, a short-reach 100GbE optical standard designed for multimode fiber infrastructure.

The SR4 architecture uses four parallel optical lanes, each operating at approximately 25Gb/s. This parallel-fiber approach enables high-speed connectivity over short data center distances.

850nm VCSEL Transmission

The module uses an 850nm VCSEL-based transmitter. VCSEL technology is widely used for short-reach multimode fiber applications because it provides an efficient optical solution for high-speed data center links.

The FTLC9559REPM uses four 25Gb/s VCSEL optical channels for the 100GbE connection. :contentReference[oaicite:4]{index=4}

100m OM4 Multimode Fiber Reach

The FTLC9559REPM supports a maximum link length of 100 meters over OM4 multimode fiber. :contentReference[oaicite:5]{index=5}

It is therefore well suited to short-distance connections within data centers, server rooms and network facilities. Actual achievable distance depends on the installed fiber type, connector quality, link loss and network equipment.

MPO-12 Connectivity

The 100GBASE-SR4 implementation uses a parallel-fiber architecture and is designed around an MPO-12 optical connection.

When deploying the FTLC9559REPM, ensure that the fiber patch cable, polarity, connector type and switch transceiver configuration are appropriate for 100GBASE-SR4 operation.

QSFP28 Hot-Pluggable Form Factor

The FTLC9559REPM uses the compact QSFP28 form factor and is designed to be hot-pluggable. This allows compatible network switches and other networking equipment to install or replace the optical module without shutting down the entire system.

Hot-plug operation depends on the host equipment and its operating procedures. Always follow the switch or router manufacturer's installation instructions.

Low-Power 100G Connectivity

The FTLC9559REPM is designed for efficient high-speed networking, with documented power dissipation of less than 2.5W and a single 3.3V power supply. :contentReference[oaicite:6]{index=6}

Low module power consumption is particularly useful in high-density data center environments where many 100GbE ports may be populated in a single switch.

Digital Diagnostics

Digital diagnostic functionality is available through the module's I²C interface, allowing compatible host equipment to monitor optical module operating information. :contentReference[oaicite:7]{index=7}

Actual diagnostic parameters displayed by the host switch depend on the switch platform, firmware and module implementation.

Operating Temperature

The documented commercial operating case-temperature range is 0°C to 70°C. :contentReference[oaicite:8]{index=8}

This range is appropriate for controlled data center and enterprise networking environments. Proper rack airflow and equipment cooling remain important for reliable operation.

100G Data Center Applications

The FTLC9559REPM is particularly suitable for short-distance high-bandwidth connections inside modern data centers.

• Switch-to-switch 100GbE links
• Switch-to-server connectivity
• Data center aggregation
• Core switch uplinks
• High-performance computing clusters
• Storage networking
• Network spine-and-leaf architectures

Finisar FTLC9559REPM vs 100GBASE-LR4

Compatibility Considerations

The FTLC9559REPM is a 100GBASE-SR4 QSFP28 optical module. The host switch, router or server adapter must support QSFP28 100GbE transceivers and the 100GBASE-SR4 standard.

• Compatible QSFP28 port
• 100GBASE-SR4 support
• OM4 multimode fiber for the specified 100m reach
• MPO-12 compatible fiber connection
• Compatible host firmware
• Appropriate optical link polarity

Transceiver compatibility can depend on the host manufacturer's coding, firmware and supported optical-module list. Verify the exact switch or network adapter compatibility before purchase.
