  • NDAA and TAA compliant for regulated government and enterprise deployments

Copper SFP pair for switch expansion

This two-pack of TRENDnet TEG-MGBRJ/2 modules converts unused SFP ports into RJ45 Gigabit Ethernet connections. Each transceiver complies with IEEE 802.3ab and IEEE 802.3z for 1000BASE-T operation over copper cabling. The hot-pluggable design allows insertion or removal without powering down the host device. They are suited for network administrators extending copper reach in managed switches or media converters.

NDAA and TAA compliance for regulated projects

The modules meet NDAA and TAA requirements, making them eligible for U.S. and Canadian federal procurement. MSA compliance ensures interoperability with a wide range of SFP-equipped hardware from different vendors. Low power consumption reduces thermal load inside dense chassis. Lifetime warranty coverage is included by the manufacturer.

Hot-pluggable RJ45 connectors up to 100m

Each unit presents a standard RJ45 jack supporting transmission distances up to 100 metres (328 ft.) over Cat5e or better cable. Data rates up to 1.25Gbps are supported across the link. The compact SFP form factor fits side-by-side in high-density port arrays. Weight is .3300 for the pair, simplifying spare-inventory logistics.

Questions about this item

Does the RJ45 connector or internal electronics in the TEG-MGBRJ/2 need periodic replacement?

The module has no moving parts or user-serviceable components; it is designed to operate for the life of the host switch without scheduled maintenance.

What limits the link distance when the transceiver runs continuously at 1.25Gbps?

The IEEE 802.3ab copper specification caps the segment at 100m (328 ft.), so cable length is the first constraint under sustained load.

How much heat and power does each module add when the switch runs all day?

Each transceiver draws low power and produces minimal heat, adding only 0.3300 lb of weight per unit without active cooling.
