Your firewall's SFP+ slot is empty, or the old transceiver just died on you during a firmware update. Either way, that 10-gigabit link to your core switch is down, and your uplink is crawling.
This is the Sophos 10GbE fiber transceiver, long range, 10 Base-LR spec. Drop it into the SFP+ port, run your fibre patch lead, and you're back at full 10-gigabit throughput over single-mode fibre. No configuration gymnastics — it's a plug-in module.
Designed for Sophos firewall and network hardware. If you're running a different vendor's box, check the transceiver spec sheet against your port before ordering.
