ITFZTCHLX-BCC | Sophos Compatible 1GB Single-Mode 10km (1000BASE-LX)

Q: Will this work in place of the Sophos ITFZTCHLX?
A: Yes. The ITFZTCHLX-BCC is engineered to the same 1000BASE-LX standard as the Sophos ITFZTCHLX, with matching SFP form factor, 1.25Gbps data rate, 1310nm wavelength, and 10km single-mode reach. It is plug-and-play compatible and tested for use in Sophos UTM, SG, and XG Series firewalls.

Q: Which Sophos firewall models support this transceiver?
A: This transceiver is compatible with Sophos UTM, SG Series, and XG Series firewall appliances that feature SFP ports. The SFP port can be onboard or provided via optional Flexi Port expansion modules on 1U and 2U models. Confirm your firewall has a Gigabit SFP slot before ordering.

Q: What type of fibre cable is required for 10km reach?
A: You need OS1 or OS2 specification single-mode fibre cable with duplex LC connectors. The 1310nm wavelength and 15dB minimum link budget support 10km transmission over standard 9/125 micron single-mode fibre. Multi-mode fibre is not compatible with this transceiver.

Q: How do I access the DOM diagnostic data?
A: Most Sophos firewall operating systems expose DOM parameters through the management interface or CLI commands. You can monitor transmit and receive optical power levels, temperature, voltage, and laser bias current in real-time to detect degraded fibre connections or approaching end-of-life conditions before link failure occurs.

Q: Can I mix this transceiver with OEM Sophos transceivers on the same firewall?
A: Yes. Because this transceiver adheres to the same IEEE 802.3z and SFP MSA standards as the OEM module, you can install it alongside genuine Sophos transceivers without compatibility issues. All transceivers on the same firewall will function independently, allowing mixed deployments during phased upgrades or budget-driven procurement.
