The FlexPoint Gx is a 1000BASE-T UTP to 1000BASE-SX/LX fiber media converter that provides reliable and cost-effective network connectivity and fiber extension.

The FlexPoint Gx auto-negotiates with most network devices for quick installations. Manual switch settings and LED indicators with on-the-label descriptions enable easy configuration with different network requirements.

The FlexPoint Gx features an auto-sensing UTP port that adjusts to the duplex and pause mode of the attached device. A switch provides manual control over the Half/Full-Duplex operation of UTP port. The port features a crossover switch that facilitates connection to a workstation or switch.

Network flow control is supported via an auto-selected or user selected Pause function that assists in relief of network congestion.

The fiber port operates at 850nm, 1310nm or 1550nm and supports SC, MT-RJ or LC connectors. Multimode models support distances up to 550m and the single-mode models support distances up to 140km.

User-selectable link modes are available to facilitate the detection of link faults. Faults can be propagated to managed devices or isolated to a per segment basis.

Diagnostic data is provided through LED indicators that assist in network installation and maintenance. The LEDs report the availability of power, port activity, link status and duplex mode.

FlexPoint modules can be mounted utilizing optional wallmounting hardware or with DIN-rail mounting brackets. They can also be rack-mounted in a 5-Module shelf or in a high-density 14-Module, power-redundant Powered Chassis.

FlexPoint modules installed in the 5-Module shelf or used as standalone devices can be powered by an external AC to DC power adapter, or through the 5VDC chassis connector. Standalone modules can also be powered by attaching an external DC power supply (18-60VDC). When used in the 14-Module power-redundant Powered Chassis with any combination of AC and DC power supplies, the installed modules are powered via the 5VDC chassis connector.

The wide variety of FlexPoint mounting and power options provide flexible upgrade paths as network requirements change and grow.

FlexPoint unmanaged media converters are easy to use and provide dependable fiber connectivity in Enterprise and Government networks around the world.
