100Gbps High-Speed Networking

The FN-TRAN-QSFP28-SR-C is designed for 100Gbps Ethernet connectivity. The QSFP28 architecture provides four optical channels that operate in parallel to achieve the aggregate 100Gbps data rate.

Fortinet describes QSFP28 as a form factor capable of supporting up to 100Gbps and lists the FN-TRAN-QSFP28-SR as its 100G short-range MPO12 transceiver. :contentReference[oaicite:3]{index=3}

100GBASE-SR4 Optical Standard

The SR4 designation indicates a short-range 100Gb Ethernet implementation using four parallel multimode-fiber optical channels.

The module uses 850nm optical transmission and an MPO/MTP multi-fiber connector. Third-party technical specifications for the FN-TRAN-QSFP28-SR-C identify it as a 100GBASE-SR4 QSFP28 transceiver with 850nm wavelength and 100m maximum reach over suitable multimode fiber. :contentReference[oaicite:4]{index=4}

850nm Optical Wavelength

The FN-TRAN-QSFP28-SR-C operates around the 850nm optical wavelength. This wavelength is commonly used with multimode fiber for short-distance high-speed data center networking.

The short-reach 850nm architecture makes this module suitable for intra-data-center connections where long-distance single-mode optical transmission is not required.

Multimode Fiber Support

The transceiver is designed for multimode fiber (MMF). Compatible OM3 and OM4 multimode fiber infrastructure can be used for appropriate 100GBASE-SR4 links.

For maximum specified reach, OM4 multimode fiber can support up to 100m, while OM3 is commonly specified up to approximately 70m for 100GBASE-SR4. :contentReference[oaicite:5]{index=5}

MPO/MTP-12 Connector

The FN-TRAN-QSFP28-SR-C uses an MPO/MTP-12 multi-fiber connector rather than a conventional duplex LC connector.

The MPO/MTP interface provides the multiple fiber channels required by the SR4 architecture. Eight optical fibers are active in a typical SR4 link: four fibers for transmission and four fibers for reception. :contentReference[oaicite:6]{index=6}

When installing the module, ensure that the MPO/MTP polarity, fiber type and connector gender are appropriate for the selected patch cable and data center cabling system.

100m Short-Range Transmission

The module is intended for short-range optical connections. With suitable OM4 multimode fiber, the specified reach can be up to 100 meters. OM3 multimode fiber is generally rated up to approximately 70 meters for this application. :contentReference[oaicite:7]{index=7}

Actual achievable distance depends on the fiber grade, connectors, patch panels, insertion loss, cleanliness and overall optical link budget.

Four Parallel Optical Lanes

The SR4 architecture uses four parallel optical lanes rather than transmitting the entire 100Gbps signal through a single optical wavelength.

Each lane operates at approximately 25Gbps, with four lanes combined to provide 100Gbps aggregate Ethernet connectivity. This parallel-fiber approach is optimized for short-distance data center environments.

VCSEL Optical Technology

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

The receiving side uses a PIN photodiode to convert the incoming optical signal back into an electrical signal.

QSFP28 Form Factor

The FN-TRAN-QSFP28-SR-C uses the compact QSFP28 form factor. QSFP28 is widely used for 100GbE networking equipment, including switches, routers, firewalls and data center platforms.

Fortinet documentation lists the FN-TRAN-QSFP28-SR as a 100 GE QSFP28 transceiver intended for systems with QSFP28 slots. :contentReference[oaicite:8]{index=8}

Hot-Pluggable Design

The QSFP28 transceiver is a pluggable optical module designed for compatible networking equipment.

Hot-pluggable installation allows supported network equipment to add or replace optical modules without powering down the complete device. Actual hot-plug behavior depends on the Fortinet platform, operating system and interface configuration.

Data Center Networking

The FN-TRAN-QSFP28-SR-C is particularly suited to modern data center networks where 100Gbps connectivity is required over short multimode-fiber links.

Typical applications include spine-to-leaf connections, switch uplinks, aggregation links, server connectivity and high-bandwidth data center interconnects.

Enterprise Core Networking

100GbE QSFP28 technology provides high-capacity links for enterprise network backbones and aggregation layers.

The SR4 module is most appropriate when the optical path is relatively short and multimode fiber infrastructure is already available.

Fortinet Compatibility

Fortinet's official documentation identifies FN-TRAN-QSFP28-SR as its 100 GE QSFP28 short-range transceiver using four-channel parallel fiber for systems with QSFP28 slots. :contentReference[oaicite:9]{index=9}

The FN-TRAN-QSFP28-SR-C designation is used in third-party compatible-transceiver catalogs for Fortinet-compatible SR4 modules. For example, Mouser lists FN-TRAN-QSFP28-SR-C as a 100GBase-SR4 QSFP28 transceiver with MMF, 850nm wavelength, 100m transmission distance and MPO connector. :contentReference[oaicite:10]{index=10}

Before purchase, verify whether the intended Fortinet device requires the original Fortinet-coded module or accepts a compatible third-party coded transceiver.

FN-TRAN-QSFP28-SR-C vs 100GBASE-LR4

Fortinet's current transceiver documentation identifies the 100G QSFP28 LR module as a 10km LC-connected single-mode 100GBase-LR4 module, distinguishing it from the short-range parallel-fiber SR module. :contentReference[oaicite:11]{index=11}

FN-TRAN-QSFP28-SR-C vs 100GBASE-DR

Fortinet's documentation describes its 100GBASE-DR module as a 500m single-mode-fiber QSFP28 transceiver, making it a different optical solution from the short-range SR4 module. :contentReference[oaicite:12]{index=12}

Compatibility Considerations

Before purchasing the FN-TRAN-QSFP28-SR-C, verify the exact Fortinet device model and QSFP28 interface requirements.

• Confirm the device has a compatible QSFP28 port
• Confirm support for 100GBASE-SR4
• Confirm Fortinet-compatible transceiver coding requirements
• Use compatible OM3 or OM4 multimode fiber
• Use an appropriate MPO/MTP-12 cable
• Verify connector polarity and gender
• Check maximum optical link distance
• Confirm firmware and transceiver compatibility where applicable

Optical Cabling Requirements

For an SR4 connection, the optical infrastructure should use suitable multimode fiber and an MPO/MTP multi-fiber connection.

OM4 fiber is preferred when the full 100m reach is required. OM3 can be used for shorter links, with approximately 70m commonly specified for 100GBASE-SR4. :contentReference[oaicite:13]{index=13}
