100Gbps High-Speed Connectivity

The FG-TRAN-QSFP28-SR4 provides high-bandwidth 100 Gigabit Ethernet connectivity in a compact QSFP28 form factor.

With an aggregate data rate of 100Gbps, it is suitable for high-throughput links between compatible switches, routers, firewalls and other networking equipment equipped with QSFP28 interfaces.

100GBASE-SR4 Optical Standard

The FG-TRAN-QSFP28-SR4 is based on the 100GBASE-SR4 short-range optical architecture. It uses four parallel optical channels over multimode fiber.

Enterprise-compatible implementations specify IEEE 802.3bm 100GBASE-SR4 and QSFP28 MSA compliance. :contentReference[oaicite:4]{index=4}

850nm Multimode Fiber

The transceiver operates at a nominal 850nm wavelength over multimode fiber. Fortinet's compatibility documentation specifically identifies the FG-TRAN-QSFP28-SR4 as an MPO/MMF/850nm short-range transceiver. :contentReference[oaicite:5]{index=5}

This makes it appropriate for short-distance data center and enterprise fiber deployments where multimode fiber infrastructure is available.

70m OM3 and 100m OM4 Reach

Documented compatible 100GBASE-SR4 implementations provide up to 70 meters over OM3 and 100 meters over OM4 multimode fiber. :contentReference[oaicite:6]{index=6}

The actual supported distance depends on fiber quality, link budget, connector condition, patching and the specific transceiver implementation.

MPO/MTP Connector

The FG-TRAN-QSFP28-SR4 uses an MPO/MTP-style parallel-fiber connector. Fortinet's documentation identifies the connector as MPO, while compatible implementations commonly specify MPO/MTP-12. :contentReference[oaicite:7]{index=7}

Because SR4 uses parallel optical lanes, the correct MPO/MTP fiber polarity and compatible multimode patch cable are important when deploying the transceiver.

Four-Channel Parallel Fiber

The SR4 architecture uses four independent optical channels for transmission and four corresponding receiving channels. Compatible implementations document approximately 25Gbps per optical lane for an aggregate 100Gbps Ethernet connection. :contentReference[oaicite:8]{index=8}

This parallel-fiber design differentiates SR4 from single-lane or wavelength-division 100GbE transceivers such as LR4 or CWDM4.

VCSEL Transmitter and PIN Receiver

Compatible technical specifications identify a VCSEL laser transmitter operating at 850nm and a PIN photodiode receiver for the four optical lanes. :contentReference[oaicite:9]{index=9}

The VCSEL-based architecture is optimized for short-reach multimode-fiber applications such as data center switching and equipment interconnects.

QSFP28 Form Factor

The FG-TRAN-QSFP28-SR4 uses the compact QSFP28 form factor. QSFP28 is widely used for 100GbE networking equipment and allows high port density in switches, routers and other data center platforms.

Fortinet documentation identifies the FG-TRAN-QSFP28-SR4 for systems equipped with compatible QSFP28 slots. :contentReference[oaicite:10]{index=10}

Hot-Pluggable Design

Compatible technical documentation identifies the SR4 transceiver as hot-pluggable. This allows supported networking equipment to install or replace the optical module without powering down the complete system, subject to the equipment manufacturer's procedures. :contentReference[oaicite:11]{index=11}

Fortinet Compatibility

Fortinet's documentation lists FG-TRAN-QSFP28-SR4 for compatible systems with QSFP ports. Fortinet's FortiDDoS documentation specifically identifies it as a 100GE QSFP28 short-range, four-channel parallel-fiber transceiver. :contentReference[oaicite:12]{index=12}

Fortinet's FortiGate 6000F Series documentation also lists FG-TRAN-QSFP28-SR4 as a 100 GE QSFP28 transceiver for systems with QSFP28 slots. :contentReference[oaicite:13]{index=13}

Always verify the exact Fortinet appliance, firmware and port compatibility before installation.

FG-TRAN-QSFP28-SR4 vs 100GBASE-LR4

Compatibility Considerations

The FG-TRAN-QSFP28-SR4 is a 100GBASE-SR4 multimode transceiver and should not be treated as a direct optical equivalent of LR4, DR or other 100GbE standards.

• Compatible Fortinet QSFP28 port
• 100GbE-capable host system
• Multimode fiber infrastructure
• Compatible MPO/MTP connector
• Correct fiber polarity
• Appropriate OM3 or OM4 fiber
