Juniper 1000BASE-T Copper SFP+ Transceiver — 30m RJ-45

The Juniper 740-083295 is a 1000BASE-T copper SFP+ transceiver delivering GbE over Cat5e/Cat6 copper cabling up to 30m via RJ-45 connector — the numeric part number equivalent to SFP-1G-T-C, for use in Juniper platforms where copper GbE connectivity is needed in SFP/SFP+ port slots.

Key Features

• 1000BASE-T copper transceiver for GbE over Cat5e/Cat6 in Juniper SFP/SFP+ port slots

Frequently Asked Questions

Why does the 740-083295 only support 30m while SFP-1G-T-C supports 100m?

The maximum copper distance listed reflects the qualified reach for the specific transceiver variant. The 30m specification on the 740-083295 reflects the Juniper-tested and supported reach for this numeric variant — for 100m copper GbE requirements, verify with Juniper whether SFP-1G-T-C's 100m rating applies to your platform and cable quality.

Can the 740-083295 be used interchangeably with SFP-1G-T-C on the same Juniper switch?

Yes — both are Juniper-genuine 1000BASE-T copper SFP transceivers and are interchangeable on the same platform. Junos OS recognizes both part numbers without warnings or operational differences.

Does the 740-083295 support PoE?

No — like all copper SFP transceivers, the 740-083295 does not support PoE pass-through. PoE requires dedicated switch port circuitry and cannot be delivered through an SFP transceiver module.

The Juniper 740-083295 provides the numeric part number alternative for Juniper copper GbE SFP connectivity — delivering 1000BASE-T RJ-45 operation in Juniper SFP/SFP+ port slots with the same platform compatibility and Juniper-genuine quality as the SFP-1G-T-C alphanumeric variant.
