Convert fiber to RJ45 Ethernet where copper alone cannot reach. This compact Gigabit media converter dongle is built for practical network extension, giving teams a simple way to connect fiber infrastructure to standard Ethernet devices without adding a full-size converter chassis. The built-in USB power cable keeps deployment straightforward, especially in spaces where power access is limited or portability matters. With one LC port and one RJ45 port, the unit is suited for bridging switches, routers, computers, and other Ethernet endpoints into fiber-based networks. It supports both single-mode and multimode optical fiber, with stated reach of up to 10 km on single-mode fiber and 800 m on multimode fiber. That makes it useful across industrial automation, telecom, broadcasting, data centers, secure facilities, and remote network extensions. The all-metal housing adds durability, while the spring-loaded tab helps protect the optical port when it is not in use. A metal RJ45 latch further supports dependable physical connection in demanding environments. For teams that need a compact, serviceable way to move traffic between fiber and copper, this converter delivers the right mix of reach, protection, and deployment flexibility.
