BTI-DW-ER-42-SFP+ Telco Systems Compatible SFP ER Transceiver

The BTI-DW-ER-42-SFP+ is a 10G ER-grade SFP+ built as a compatible replacement for the Telco Systems part of the same number. It handles the extended-reach role the ER designation implies, seating in a standard SFP+ cage and coming up coded to the host so the interface recognizes it on insertion with no configuration to enter.
