Fortinet FN-TRAN-QSFP28-LR QSFP28 Transceiver

FN-TRAN-QSFP28-LR Exact Order Identity

FN-TRAN-QSFP28-LR is a 100 GE QSFP28 optical transceiver. It is a physical connectivity item, not a FortiCare or FortiGuard service entitlement.

Interface and Link Role

Duplex LC optical interface. The documented link role is 100GBASE-LR4 over single-mode fibre. The applicable host interface is Systems with QSFP28 slots.

Length or Reach

10 km reach. The documented operating condition is 0 C to 70 C.

Model-Specific Acceptance

Measure the installed single-mode path and record transmit/receive levels at turnover; the LR code is the 10 km variant, not the 20 km ER unit.

Deployment Record for This Order Line

For the 10 km LR4 circuit, preserve the route length, fibre type, patch-panel inventory, insertion-loss test and transmit/receive readings. Check that the LR optical range fits the actual path without unnecessary long-reach substitution, and retain a baseline so later power drift can be distinguished from an interface fault.

Procurement Boundary

Match the full SKU, connector or cable geometry, endpoint port type, link mode, quantity and route. Confirm current Fortinet platform compatibility and the accepted bill of materials; do not substitute a similar-looking form factor.

Official Evidence

Fortinet official transceiver and cable catalog is the manufacturer reference used for this audit. Where the exact order row is absent from the current public catalog, written Fortinet order confirmation remains mandatory.
