Transition Networks
Converts 1000Base-T copper to 1000Base-SX multimode fiber up to 1804.5 ft with auto-negotiation and transparent link pass-through
The Transition Networks SGETF1013-110-NA converts a 1000BASE-T copper link to a 1000BASE-SX 850 nm multimode fibre link. It suits installers who need to extend a Gigabit connection beyond the 100 m copper limit using existing multimode cabling.
The stand-alone unit has no fans and draws power from an external supply, so it adds no audible noise to the rack or wall mount. Auto-negotiation on both the RJ-45 and SC interfaces selects the optimum duplex mode without manual configuration.
The housing measures 1 in high, 3.25 in wide and 4.80 in deep, fitting easily on a shelf or DIN rail clip. A single SC duplex connector handles transmit and receive fibres, while the RJ-45 port accepts shielded or unshielded twisted-pair cable up to 100 m.

| Features | Auto-Negotiation (802.3u) (Copper & Fiber) Allows devices to perform automatic configuration to achieve the best possible mode of operation over a link. Transparent Link Pass Through Transparent Link Pass Through sends a link-loss signal over the fiber, instructing the remote converter to shut down the copper port—thus notifying the end device—while maintaining the fiber link between the two converters. Automatic Link Restoration Transition Networks's converters will automatically re-establish link in all network conditions. Pause (IEEE 802.3xy) Pause signaling is an IEEE feature tha |

Connect the 1000BASE-T RJ-45 port to copper cable up to 100 m and the 1000BASE-SX SC duplex port to multimode fibre; the step often missed is enabling Auto-Negotiation on both linked devices so the link passes through transparently.
The unit has no moving parts or user-replaceable modules; maintenance is limited to keeping the SC connectors clean and verifying the fibre patch cords (62.5/125 µm or 50/125 µm) remain undamaged.
The fibre distance limit is reached first: 220 m on 62.5/125 µm multimode or 550 m on 50/125 µm multimode at 850 nm, while the copper side supports 100 m.
