Fortinet FN-TRAN-QSFP28-ER QSFP28 Transceiver

FN-TRAN-QSFP28-ER Exact Order Identity

FN-TRAN-QSFP28-ER 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-ER4 over single-mode fibre. The applicable host interface is Systems with QSFP28 slots.

Length or Reach

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

Model-Specific Acceptance

Document the 20 km optical budget, connector cleanliness, patch losses and receive-power range; do not substitute the 10 km LR order line without redesign.

Deployment Record for This Order Line

For the 20 km ER4 circuit, build a complete single-mode optical budget that includes transmitter range, receiver limits, fibre attenuation, connector and splice loss, engineering margin and any intermediate panels. Record cleaned LC connectors and measured receive power at both ends; an ER design should not be accepted from link-up status alone.

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.
