Copper SFP Transceiver

The Zenitel SFP-CU1G is a small form-factor pluggable networking module for compatible ASL/Zenitel public address and voice alarm equipment. It provides a RJ45 copper cabling connection, with Zenitel specifying up to 90 m of link distance.

Main benefits and key functions

The copper version is intended for shorter links over conventional network cable and avoids the need for fibre termination at the connection. It is not an optical transceiver despite the generic category wording on the manufacturer page. As a modular SFP, it allows the appropriate media type to be selected for the link without changing the whole network switch. Zenitel identifies compatibility with the NETWORK-SWITCH-LP01 and EN 54 certification in the stated system context. The important purchasing decision is the cable medium, available reach and switch compatibility. Confirm these points before installation because different SFP types are not direct substitutes for one another.

Typical applications

Use this module when connecting network equipment within a PAVA cabinet or between linked equipment locations. Fibre variants can help where longer cable runs or electrical isolation are needed; the RJ45 copper version is a separate choice for shorter runs. Match the SFP at both ends to the installed cable and switching equipment.

Connectivity and installation

This is an SFP interface module, not a standalone network switch. It plugs into a suitable host SFP slot and connects using RJ45 electrical. The manufacturer states 1 Gbit copper link. Plan link distance, cable specification and compatible host ports before ordering so commissioning work is straightforward.

Specification and purchasing guidance

For installers and specifiers, the SFP-CU1G should be matched to the host equipment, cabling and operating conditions shown on the project drawings. Keep the model number in the system schedule so future maintenance teams can identify the correct version. Check any optional accessories separately rather than assuming they are supplied with the base product.

Summary

The Zenitel SFP-CU1G offers a focused solution for its documented role. Its main strengths are the specific functions and compatibility described above, making it a practical choice when those requirements are part of the installation. Order the exact version that matches the system design.
