10G Copper SFP+ Transceiver

The Black Box LSP443 is a 10G Base-T RJ45 copper SFP+ transceiver built for network links up to 30 metres. It suits administrators who need 10‑Gbps connectivity over existing Cat6a or Cat7 copper cabling without deploying fibre.

Sustained Link Behaviour

The module maintains a 10‑Gbps rate across the full 30‑metre copper reach. Copper PHY operation keeps latency low and power draw steady during continuous traffic, avoiding the thermal throttling sometimes seen in longer‑reach optics.

Installation Notes

The SFP+ form factor slides into any compliant cage and locks with the standard bail latch. The RJ45 jack accepts standard patch cords; no fibre polishing or polarity checks are required. Ensure the host port supplies adequate power for the copper PHY and verify that the switch port is configured for 10G Base-T rather than a fibre mode.

Questions about this item

How much power does the LSP443 draw when running at 10 Gbps all day?

The LSP443 is a 10 Gbps SFP+ copper transceiver rated for 30 m links; it draws power from the host SFP+ cage and does not need an external adapter.

What host equipment must I already have for the LSP443 to work?

You need a switch, router or NIC with an SFP+ cage that supports 10GBASE-T copper modules and standard RJ45 cabling.

Will the LSP443 negotiate down to 1 Gbps on my older Cat5e patch panel?

The module is specified for 10 Gbps over 30 m; speed negotiation depends on the host port and cable quality, not the transceiver itself.
