100GbE High-Speed Connectivity

The FN-TRAN-QSFP28-LR provides a 100 Gigabit Ethernet optical interface for high-bandwidth network infrastructure. It is suitable for applications where 10GbE or 25GbE connectivity is insufficient and a high-capacity 100GbE link is required.

The QSFP28 form factor combines high bandwidth with a compact physical footprint, making it suitable for high-density switches and data center networking equipment.

100GBASE-LR4 Technology

The FN-TRAN-QSFP28-LR uses the 100GBASE-LR4 optical standard. LR4 is designed for long-range 100GbE transmission over single-mode fiber with a typical reach of up to 10km.

The optical system uses four LAN-WDM channels around the 1310nm wavelength window. Each optical channel carries approximately 25Gbps, combining to provide the 100GbE optical link.

Fortinet's official documentation identifies the FN-TRAN-QSFP28-LR as a 100GBase-LR4, 10km, LC and SMF transceiver. :contentReference[oaicite:3]{index=3}

10km Transmission Distance

The FN-TRAN-QSFP28-LR is designed for optical links of up to 10km when used with suitable single-mode fiber and compatible network equipment.

Actual deployment distance depends on fiber attenuation, connector losses, splice losses, optical power budget and the characteristics of the connected network devices.

Single-Mode Fiber Support

The FN-TRAN-QSFP28-LR is designed for single-mode fiber (SMF). Single-mode fiber is appropriate for long-distance optical networking and provides significantly greater reach than conventional multimode fiber architectures.

For a 10km LR4 link, use suitable OS2 single-mode fiber infrastructure and compatible duplex LC termination.

Duplex LC Connector

The transceiver uses a duplex LC optical connector. A duplex LC connection uses separate transmit and receive optical paths within the fiber pair.

Ensure that the installed fiber patch cable and structured cabling infrastructure use compatible LC connectors and single-mode fiber.

1310nm LAN-WDM Optical Architecture

The FN-TRAN-QSFP28-LR operates in the 1310nm optical window using LAN-WDM channels. This architecture allows multiple optical wavelengths to travel over a single duplex single-mode fiber pair.

Representative LR4 wavelength channels are approximately 1295.56nm, 1300.05nm, 1304.58nm and 1309.14nm. These channels are multiplexed within the 1310nm window rather than representing a single 1310nm optical channel. :contentReference[oaicite:4]{index=4}

QSFP28 Form Factor

The FN-TRAN-QSFP28-LR uses the QSFP28 form factor. QSFP28 is widely used for 100GbE switching and data center networking applications.

The compact form factor enables high-density 100GbE port deployments in compatible Fortinet switches and other supported networking platforms.

Digital Diagnostic Monitoring

Compatible FN-TRAN-QSFP28-LR implementations support DDM/DOM, allowing supported network equipment to monitor optical and module operating parameters.

Depending on the host platform and optic implementation, diagnostic information can include module temperature, supply voltage, laser bias and transmit/receive optical power.

Commercial Temperature Range

Fortinet specifies the FN-TRAN-QSFP28-LR for a commercial operating temperature range of 0°C to 70°C. :contentReference[oaicite:5]{index=5}

For installations requiring an extended industrial temperature range, verify the exact Fortinet optic SKU before ordering because Fortinet offers different transceiver variants for different environmental requirements.

Fortinet Compatibility

Fortinet's compatible-transceiver documentation lists FN-TRAN-QSFP28-LR as a 100G QSFP28 transceiver and identifies the associated FTLC1154RDPL optic family. :contentReference[oaicite:6]{index=6}

Fortinet's FortiGate 6000F Series documentation also lists FN-TRAN-QSFP28-LR as a 100 GE QSFP28 long-range transceiver for compatible systems with QSFP28 slots. :contentReference[oaicite:7]{index=7}

Always verify the exact Fortinet device model and supported transceiver list before purchasing, as compatibility can vary between hardware platforms and firmware versions.

Data Center Networking

The FN-TRAN-QSFP28-LR is well suited to data center environments where 100GbE links are required between switches, routers and high-performance infrastructure.

• Spine-to-leaf connectivity
• Core-to-distribution links
• Data center interconnects
• High-performance server aggregation
• Storage network connectivity
• Cloud infrastructure

Enterprise Backbone Connectivity

With up to 10km of single-mode fiber reach, the FN-TRAN-QSFP28-LR can be used for enterprise backbone connections between network equipment located in different rooms, floors or buildings where the fiber path remains within the supported optical budget.

Optical Link Planning

For reliable 10km deployment, optical link planning should account for the complete fiber path rather than simply relying on the nominal 10km specification.

• Single-mode fiber type
• Total fiber distance
• Connector insertion loss
• Splice loss
• Optical power budget
• Patch-panel losses
• Transceiver compatibility
• Host device configuration

FN-TRAN-QSFP28-LR vs 100G SR4

Compatibility Considerations

The FN-TRAN-QSFP28-LR should be installed only in network equipment that supports the appropriate QSFP28 transceiver and 100GBASE-LR4 configuration.

• Compatible QSFP28 slot
• 100GbE host interface support
• 100GBASE-LR4 support
• Single-mode fiber infrastructure
• Duplex LC connectivity
• Appropriate optical link budget
• Compatible Fortinet firmware and hardware

Do not confuse FN-TRAN-QSFP28-LR with Fortinet's 100G SR, DR, FR, CWDM4 or ER transceiver variants. These products have different optical standards, connector types and transmission distances.
