Product Overview
The Adder SFP-CATX-RJ45 is a 1Gbps copper SFP transceiver with an 8p8c (RJ45) connector that links Adder KVM-over-IP devices to standard CATx structured cabling. Compliant with the Gigabit Ethernet and 1000BASE-T standards defined in IEEE 802.3-2002 and IEEE 802.3ab, this copper SFP module for KVM extenders carries 1000Mbps over unshielded twisted-pair Category 5 cable up to 100 meters. It is the standard choice for populating the SFP cage on ADDERLink INFINITY endpoints when copper runs are the right fit.
Product Description
Adder's IP KVM hardware, including the ADDERLink INFINITY extender family, is fitted with SFP cages so that installers can match the physical link to the building: copper for short structured-cabling runs, fiber where distance or interference demands it. The SFP-CATX-RJ45 fills that cage with a 1GbE copper interface.

The module supports a full 1000Mbps data rate over unshielded twisted-pair Category 5 cable at distances up to 100 meters, which matches the typical horizontal cabling limit in commercial buildings. Because it conforms to the IEEE 1000BASE-T standard, it interoperates with standard Gigabit Ethernet switch ports as well as Adder endpoints, letting an ALIF transmitter or receiver join the same structured cabling plant as the rest of the network.

Specifying the vendor's own transceiver avoids the compatibility guesswork that comes with third-party optics and keeps the whole signal path under one support umbrella. For runs beyond 100 meters or electrically noisy paths, Adder's single-mode and multi-mode fiber SFP modules drop into the same cage. Find the fiber alternatives, ALIF endpoints, and the rest of the lineup in the Adder Technology collection at Creation Networks.
Key Features
- 1GbE over Copper — Delivers a full 1000Mbps data rate over unshielded twisted-pair Category 5 cable.
- 100-Meter Reach — Supports runs up to 100 meters, matching standard horizontal structured-cabling limits.
- Standards Compliant — Meets Gigabit Ethernet and 1000BASE-T standards per IEEE 802.3-2002 and IEEE 802.3ab.
- RJ45 (8p8c) Connector — Terminates directly onto existing CATx patch cabling with no media conversion.
- Vendor-Matched for Adder KVM — Designed for the SFP cages on Adder KVM-over-IP devices such as ADDERLink INFINITY endpoints.
- Swappable Link Media — Shares a cage format with Adder fiber SFPs, so links can be upgraded to fiber without changing the endpoint.
