Fortinet FN-TRAN-SFP-1BU40 1 GE 40 km BiDi SFP Transceiver is listed by YYST Global for buyers looking for FORTINET Transceiver Modules. FN-TRAN-SFP-1BU40 is the U-side Fortinet 1 GE BiDi SFP for 40 km single-mode-fiber connections. Its optical direction is TX 1310 nm and RX 1490 nm through a simplex LC interface. The listed condition is New Factory Sealed. The reference price is US$ 225.00. Contact our sales team to validate compatibility, scope, fulfillment and lead time before ordering.
FN-TRAN-SFP-1BU40 is the upstream member of Fortinet's 40 km 1 GE single-fiber pair. It sends at 1310 nm and receives at 1490 nm, the reverse of FN-TRAN-SFP-1BD40. Fortinet lists a 1.25 Gbps Ethernet data-link rate, simplex LC connector and single-mode-fiber media.
The BU40 code identifies a wavelength role, not a generic duplicate of the BD40 optic. One BU40 and one BD40 are required for a bidirectional circuit. Both modules are hot-pluggable, expose link status and digital monitoring, and are specified for -40 to 85 degrees C operation. Optical budget and platform support still need validation for the exact deployment.
