STARTECH ET91000SM10 Gigabit Ethernet Copper-to-Fiber Media Converter SM LC 10 km

Gigabit Ethernet copper-to-fiber converter

The STARTECH ET91000SM10 converts a 1000 Mbps copper Ethernet link to single-mode LC fiber, extending the connection up to 10 km (6.2 mi). It is aimed at network administrators and installers who need to bridge buildings or distant cabinets without deploying active switches at every endpoint. A universal AC adapter is included for standalone operation. The rugged metal housing suits commercial environments.

10 km reach on single-mode fiber

The converter operates at a 1310 nm wavelength and supports jumbo frames, link-fault pass-through and automatic laser shutdown for safe fiber handling. It comfortably handles full Gigabit throughput across the 10 km distance. Beyond that range the optical budget is exceeded and signal integrity cannot be guaranteed. The unit draws up to 19.2 W from the supplied adapter.

Standalone or chassis-mounted deployment

The device measures 6.40" x 3.50" x .90" and weighs .91 lb, fitting on a desk, DIN rail or wall bracket. It can also slide into the optional ETCHS2U rackmount chassis for high-density installations. No software configuration is required; status LEDs report power, fiber link, copper link and duplex mode at a glance. The package includes the converter, a multi-region power adapter and an instruction manual.
