The FlexPoint 100Fx/Tx is a 100BASE-FX fiber to 100BASE-TX UTP media converter that provides reliable and cost-effective network connectivity and fiber extension.

The FlexPoint 100Fx/Tx UTP port auto-negotiates to the highest level of performance supported by the attached device. Manual switch settings and LED indicators with on-the-label descriptions enable easy configuration to legacy devices or matching specific network requirements.

The FlexPoint 100Fx/Tx fiber port operates at 1310nm or 1550nm and supports SC or ST connectors. Multimode models support distances up to 5km and single-mode models support distances up to 120km.

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

The FlexPoint 100Fx/Tx features a crossover switch that eliminates the need for a crossover cable and facilitates connectivity to network equipment such as switches or workstations.

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.

In this enterprise campus application example, FlexPoint 100Fx/Tx media converters are installed in a 14-Module Redundant Power chassis for high-density fiber distribution from UTP switch equipment at the Network Core. A UTP workgroup switch (A) is connected via fiber with a standalone FlexPoint 100Fx/Tx media converter. Another FlexPoint 100Fx/Tx converts the fiber to UTP in a fiber-to-desktop application (B). An Ethernet switch (C) is connected directly via fiber to the FlexPoint module at the Network Core. In all cases, multimode or single-mode fiber can be used, and fiber links can be extended up to 120km using single-mode fiber.
