SFP-kuparilähetin-vastaanotin CBO SFP-3841 1 Gbit/s Ethernetille twisted-pair-kaapelilla

CBO SFP-3841 is a 1 Gbps copper SFP transceiver that provides a Gigabit Ethernet interface over standard twisted-pair copper cabling. Designed for insertion into compatible SFP ports, the module enables short-reach device interconnects, uplinks and link extensions in network switches, routers and media converters without requiring a fixed RJ45 port on the host device. The compact SFP form factor preserves port density while delivering a familiar copper connection for Ethernet over CAT5e/CAT6 type cabling.

Advantages

The transceiver supports 1 Gbps data rates and is compatible with standard SFP cages, offering straightforward hot-pluggable installation and easy replacement. Its copper interface eliminates the need for fiber patching on short links and simplifies wiring in office and data center racks. The small form factor conserves space on chassis-based equipment while providing reliable electrical Ethernet signaling and interoperability with devices that accept SFP copper modules.

Key specifications

How to use

Install the module by inserting it into an available SFP port on a compatible switch, router or media converter until it latches securely. Connect a standard copper Ethernet cable to the module's RJ45 interface and the remote device. The link should negotiate to 1 Gbps full duplex automatically when both ends support the same speed and autonegotiation. Remove the module by pressing the release mechanism on the host port and pulling the module straight out when required.

Recommendations

Use certified Category 5e or Category 6 cabling for reliable 1 Gbps performance and keep copper cable runs within standard Ethernet distance limits for 1000BASE-T. Confirm host device compatibility with copper SFP modules and verify link settings in the network equipment to ensure correct speed and duplex. Avoid installing or removing the module while exposed to strong electrical interference or when physically stressed.
