Gigabit 1000Base-T Fiber converter

Gigabit 1000Base-T copper to
1000Base-SX 850nm multimode, 1310 multi-mode fiber converter

10/100/1000BASE-T (RJ-45) [100 m/328 ft.] copper
to 1000BASE-SX 850nm multimode (SC) [62.5/125µm: 220 m/722 ft.; 50/125µm: 550 m/1804 ft.

10/100/ 1000BASE-T (RJ-45) [100 m/328 ft.] copper
to 1000BASE-SX 1310nm Extended multimode (62.5/125 μm fiber only) (SC)
[up to 2 km]


10/100/1000 media converter that converts the electrical signal of a 10/100/1000 Ethernet signal from copper to fiber. This solution will offer a low-cost integration option for network managers who want to migrate from 10/100 networks to Gigabit Ethernet. Gigabit only switches can now be connected to 10/100 networks without the need to upgrade the 10/100 side, allowing network managers to add new equipment gradually.

Fiber interface runs at 1000Base speeds, which enables users to connect Gigabit ports on fiber switches. Fiber connectivity options include SX optics and LX dual fiber with distances up to 125km or single fiber up to 40km. In addition to the standard 220 meters with standard SX optics, Transition Networks also offers a proprietary solution that will allow users to transmit up to 2km over multimode fiber (62.5/125µm) (xGFEB1024-100).

Auto-Negotiation (802.3u)
Allows devices to perform automatic configuration to achieve the best possible mode of operation over a link.
AutoCross™ (on copper port)
Automatically detects and configures the twisted pair port on the converter to the correct MDI or MDI-X configuration.
Link Pass Through
Link Pass Through is a troubleshooting feature that allows the media converter to monitor both the fiber and copper RX ports for loss of signal.
Pause (IEEE 802.3xy)
Pause signaling is an IEEE feature that temporarily suspends data transmission between two devices in the event that one of the devices becomes overwhelmed.
