FN-TRAN-FX-BCC | Fortinet Compatible 100MB Multi-Mode - 2km (100BASE-FX)

Q: Will this work in place of the FN-TRAN-FX?
A: Yes. The FN-TRAN-FX-BCC matches the 100BASE-FX standard, SFP form factor, 100 Mbps data rate, 1310nm wavelength, and 2km multi-mode reach of the original Fortinet transceiver. This module is plug-and-play compatible and can be installed directly into any SFP slot that supports the FN-TRAN-FX.

Q: Which Fortinet platforms support this transceiver?
A: This transceiver works in Fortinet systems with SFP slots capable of 10/100MB mode selection, including FortiSwitch models like the FS-424E-Fiber (ports 1-24) and FSR-424F-POE (ports 13-24). Any Fortinet device with an SFP slot supporting 100BASE-FX transceivers can use this module.

Q: What fibre types and core sizes does this transceiver support?
A: The FN-TRAN-FX-BCC supports multi-mode fibre with 50/125 micron, 62.5/125 micron, or 100/140 micron core sizes. Maximum reach of 2km applies with adequate optical budget. The 1310nm wavelength used by this transceiver is optimised for multi-mode fibre transmission in the lower attenuation window.

Q: Can I use this transceiver in a standard temperature network environment, or is the industrial rating required?
A: The industrial temperature rating (-40°C to 85°C) is a capability, not a requirement. This transceiver operates reliably in standard office or data centre environments (0°C to 70°C) and also supports deployment in outdoor cabinets, manufacturing floors, or other harsh environments where standard temperature transceivers would fail.

Q: How do I access the DOM diagnostics on this transceiver?
A: DOM parameters are accessed via the 2-wire I2C serial interface at address A0h (base data) and A2h (diagnostic data) as defined in SFF-8472. Most modern Fortinet platforms provide CLI commands or GUI dashboards to query transmit power, receive power, temperature, voltage, and laser bias current. The transceiver reports diagnostic data in real time without requiring special configuration.
