GLC-FE-100FX-RGD-BCC | Cisco Compatible 100MB Multi-Mode - 2km (100BASE-FX) Rugged / Industrial

Q: Will this work in place of the Cisco GLC-FE-100FX-RGD?
A: Yes. The GLC-FE-100FX-RGD-BCC is electrically and mechanically identical to the Cisco GLC-FE-100FX-RGD and provides the same 100BASE-FX interface at 100 Mbps over multi-mode fibre. It is plug-and-play compatible with any Cisco Fast Ethernet SFP port or dual-rate Fast/Gigabit Ethernet port that accepts the original Cisco module, with no configuration changes required.

Q: Which Cisco platforms support this transceiver?
A: This transceiver operates in any Cisco switch or router with Fast Ethernet SFP ports or dual-rate Fast/Gigabit Ethernet SFP ports. It is specifically designed for Cisco Industrial Ethernet and SmartGrid platforms that require the industrial temperature range. Consult Cisco's 100M Ethernet SFP Compatibility Matrix for detailed platform support, as specific platform families are subject to software and hardware revision.

Q: What multi-mode fibre types are supported for the full 2km reach?
A: The 2km reach specification assumes OM1 (62.5/125 µm) or better multi-mode fibre with an 8.5 dB link budget. Higher-grade fibres such as OM2, OM3, or OM4 will also work and may extend reach slightly depending on splice loss and connector quality. The minimum cable distance is 2 metres. Actual reach depends on total insertion loss of the fibre path, including connectors, splices, and fibre attenuation.

Q: Can I monitor optical power and temperature in real time?
A: Yes. This transceiver includes Digital Optical Monitoring (DOM) accessible via the I2C interface on the SFP connector. DOM exposes transmit power, receive power, supply voltage, bias current, and temperature in real time. Most Cisco platforms expose these parameters through CLI commands or SNMP MIBs, allowing you to monitor link health and detect degraded optics or fibre before a link fails.

Q: What makes the industrial temperature rating critical for this transceiver?
A: The -40°C to +85°C industrial temperature range allows this transceiver to operate in outdoor cabinets, utility substations, factory automation enclosures, and other environments where ambient temperature exceeds the 0°C to +70°C limit of commercial-grade optics. Industrial-rated transceivers use components and assembly processes that maintain stable laser output, receiver sensitivity, and DOM accuracy across the extended temperature range, preventing link flapping or failure during temperature excursions.
