ITFZTCHTC-BCC | Sophos Compatible 1GB Ethernet RJ45 100m (1000BASE-T)

Q: Will this work in place of the Sophos ITFZTCHTC?
A: Yes. The ITFZTCHTC-BCC delivers IEEE 802.3ab compliant 1000BASE-T operation in the SFP form factor, matching the original Sophos ITFZTCHTC specification. It provides plug-and-play compatibility with Sophos platforms that accept standard 1000BASE-T SFP modules.

Q: Which Sophos platforms support this transceiver?
A: This module is compatible with Sophos network equipment featuring standard SFP ports that support 1000BASE-T copper transceivers. Compatibility is defined by the presence of an SFP slot that accepts MSA-compliant copper SFP modules. Consult Sophos documentation or contact Blue Cable Co to confirm compatibility with your specific model and firmware version.

Q: What cable type and length does 1000BASE-T require?
A: IEEE 802.3ab specifies four-pair Category 5 or better balanced copper cabling with a maximum segment length of 100 meters. Cat5e is recommended as a minimum for reliable Gigabit Ethernet operation. Cat6 and Cat6a cables provide additional headroom for crosstalk and insertion loss. The 100m limit includes patch cables at both ends of the permanent link.

Q: Does this module support Power over Ethernet pass-through?
A: No. This is a data-only SFP transceiver. Power over Ethernet (PoE, PoE+, or PoE++) is delivered by the host switch through its RJ45 copper ports, not through SFP slots. If you require PoE delivery to downstream devices, use the switch's built-in copper Ethernet ports rather than SFP slots with copper transceivers.

Q: Can I use this module at 100 Mbps or 10 Mbps speeds?
A: Yes. This transceiver supports 10/100/1000 Mbps auto-negotiation as part of the 1000BASE-T standard. When connected to a Fast Ethernet (100BASE-TX) or legacy 10BASE-T link partner, the module will negotiate down to the highest mutually supported speed and duplex mode. All four pairs remain active during 1000 Mbps operation; 100 Mbps and 10 Mbps use two pairs.
