Gigabit RJ45 to 1000Base-FX SFP Fiber Media Converter with PoE Injector | 10/100/1000Base-T Copper-to-Fiber Extender | POEJK-FEI

10/100/1000Base-T RJ45 to 1000Base-FX SFP Fiber Extender / Media Converter

The POEJK-FEI is described in the GRID dealer price list as a “10/100/1000Base-T RJ45 to 1000Base-FX SFP Fiber Extender … Injector Media Converter”. It bridges 10/100/1000Base-T copper Ethernet to a 1000Base-FX SFP fiber interface, letting you extend network links over fiber where copper alone isn’t practical.

Use POEJK-FEI to connect copper-only devices or switch ports into a fiber backbone using compatible 1000Base-FX SFP modules.

Key features

• 10/100/1000Base-T RJ45 interface – supports standard copper Ethernet at 10, 100 or 1000 Mbps.
• 1000Base-FX SFP fiber port – SFP slot for 1000Base-FX fiber transceivers.
• Fiber extender / media converter – converts copper Ethernet to fiber for longer runs or optical backbones.
• “Injector Media Converter” designation – per GRID price list wording (detailed power/PoE behavior should be confirmed in the latest spec sheet).

Technical highlights

Ideal applications

• Extending Gigabit Ethernet from copper switches to remote locations over fiber.
• Bridging copper-only equipment into a 1000Base-FX fiber backbone.
• Retrofits where new fiber is available but attached devices expose only RJ45 ports.

Compatibility & ecosystem

POEJK-FEI sits alongside GRID’s SFP modules such as SF-MMLC (1000BASE-SX SFP transceiver) in the price list, indicating it is intended for use with 1000Base SFP optics. It can be used to link remote PoE switch locations, media enclosures or consolidation points back to the main network fabric over fiber.

Only attributes explicitly present in the GRID price list are used here. For detailed PoE behavior, power requirements and optical specifications, refer to the latest POEJK-FEI datasheet from GRID Networking.
