100GBASE-SR4 Optical Technology

100GBASE-SR4 is a short-reach 100Gbps Ethernet optical technology that uses four parallel optical lanes over multimode fiber. The Finisar FTLC9551REPM uses four 850nm VCSEL-based optical transmit channels, with each lane operating at approximately 25Gbps.

This parallel architecture makes the FTLC9551REPM particularly suitable for high-density data center environments where network devices are located relatively close to each other. It provides substantially higher bandwidth than 40G or 10G optical links while maintaining a compact QSFP28 form factor.

QSFP28 Form Factor

The QSFP28 form factor is designed for high-density 100Gbps networking. The Finisar FTLC9551REPM provides a compact, hot-pluggable interface that can be installed in compatible 100G switches, routers, network adapters, and other networking platforms.

Hot-pluggable operation makes the module convenient for supported network environments where optical modules may need to be installed, replaced, or upgraded without powering down the entire host system.

MPO12 Multimode Fiber Connectivity

The FTLC9551REPM uses an MPO12 receptacle for its parallel optical interface. Proper MPO/MTP cabling, fiber polarity, connector type, and lane mapping are important when deploying a 100GBASE-SR4 link.

For OM4 multimode fiber, the module supports up to 100 meters, while OM3 supports up to 70 meters. The complete optical link should be checked for insertion loss and other channel limitations before deployment. :contentReference[oaicite:5]{index=5}

Digital Diagnostic Monitoring

The Finisar FTLC9551REPM provides digital diagnostic functionality through its I2C management interface. Supported host equipment can use this interface to monitor optical and operating parameters and assist with network troubleshooting and maintenance. :contentReference[oaicite:6]{index=6}
