HP® J8177C Compatible TAA 10/100/1000Base-TX SFP Transceiver (Copper, 100m, RJ-45)

The AddOn J8177C-AO is an HP J8177C-compatible copper SFP transceiver with an RJ-45 port for 10/100/1000Base-T connections up to 100 meters, suited to network teams connecting compatible equipment over twisted-pair Ethernet.

Recommended For

• Network administrators adding an RJ-45 copper connection to a compatible HP/Aruba switch SFP port, especially when they need to use existing Ethernet cabling rather than install fiber. Confirm the exact switch model and port compatibility first.
• IT teams connecting nearby switches or network devices over existing Cat5e-or-better copper runs, where a 1Gbps link and a maximum 100-meter reach meet the requirement.
• Admins who need to add a copper endpoint to a switch with available SFP slots—for example, to connect an Ethernet device where the switch’s built-in RJ-45 ports are already in use.
• Teams maintaining compatible legacy HP ProCurve or Aruba networks that need a 1Gbps RJ-45 SFP replacement or expansion module, provided the specific switch and port are listed as supported.

Real-World Use Scenarios

• When a compatible HP switch has an unused SFP slot but a nearby device uses Ethernet, this module lets the user connect it with a standard RJ-45 cable instead of fiber; the link can run at gigabit speed when both ends support it.
• When a switch’s built-in RJ-45 ports are already in use, a supported SFP slot can provide another copper network connection for a server, NAS, or other Ethernet device; the device must negotiate a speed supported by the switch and transceiver.
• For a switch-to-switch link where copper cabling is already installed, the module can connect the SFP-equipped switch to a gigabit Ethernet port on the other switch, avoiding a new fiber run; check that the SFP port and both devices support the intended link speed.
• When extending a wired connection across an office, classroom, or equipment room, the module can use an existing copper Ethernet run between the switch and a compatible endpoint, within the supported cable reach; the HPE specification lists up to 100 meters.
• For a 100 Mbps legacy device, use this only if the specific switch model and software support 100 Mbps operation through the J8177C-compatible module; HPE documents that support as platform-dependent, so it may not link automatically on every switch.
