For fiber, these converters use ST connectors. They come in

850-nm multimode, 1300-nm multimode, and 1300-nm single-

mode models. The fiber length is limited to 1.2 miles (1.9 km)

per IEEE 802.3 timing.

On the coax side, the converters have BNC connectors and

support 50-ohm cable at distances of up to 607 feet (185 m). You

can connect up to 30 workstations to this segment per the 802.3

IEEE standard.

A switch-selectable terminator is built in.

10BASE-T to 10BASE-FL

These media converters join unshielded twisted-pair (UTP)

and fiber LANs into one network. They support half- and full-duplex

(10- and 20-Mbps) operation.

For fiber, these converters use SC or ST® connectors in 850-nm

multimode, 1300-nm multimode, 1300-nm single-mode, or 1550-nm

single-mode.

For UTP, these media converters use an EIA/TIA modular 568

RJ-45 connector and support Category 3, 4, and 5 wiring, connecting

at distances up to 328 feet (100 m).

10BASE-T to 10BASE-FL converters also correct wiring-polarity

reversals and eliminate crossed cables with a crossover switch.

100BASE-TX to 100BASE-FX

This group of media converters connects Fast Ethernet 100BASE-

FX fiber to 100BASE-TX UTP LANs. They use auto-negotiation for

full- and half-duplex operation and can handle numerous fiber types.

These converters auto-adapt to the highest performance level

supported by the device that is connected to the UTP port. When the

device supports full-duplex, the converter adapts to full-duplex mode

and creates a 200-Mbps bandwidth. When the connected device

supports only half-duplex, the converter adapts to this mode and

creates a 100-Mbps bandwidth. Full- and half-duplex operation

can also be controlled by a manual override switch.

The fiber side of these converters operates at 1300 nm or 1500

nm and uses ST or SC connectors. Multimode models can support

distances of up to 1.2 miles (2 km), and the single-mode models

can operate at distances of 68.4 miles (110 km).

The UTP port, which supports distances of up to 328 feet

(100 m), has a modular 568 RJ-45 connector for Category 5 wiring.

A crossover switch eliminates the need for crossed cables.

Gigabit UTP to Fiber

Use FlexPoint Gigabit UTP to Fiber Media Converters to convert

Gigabit Ethernet 1000BASE-T unshielded twisted-

pair (UTP) cable to 1000BASE-SX single- or 1000BASE-LX multimode

fiber. The converters comply with the IEEE 802.ab standard.

The converters auto-adapt to the full-/half-duplex and flow-control

services supported by the device connected to its UTP port. User-

selectable override options set the desired mode.

The converters operate in full-duplex to provide an effective

2-Gbps data rate or in half-duplex mode to provide a 1-Gbps rate.

This maximizes the throughput when connecting to high-bandwidth

full-duplex services such as servers or switches.

Network flow control is supported via an auto-selected or user-

selected “Pause” function that helps relieve network congestion

by providing “backpressure” to the sending device.

The converter supports 850-nm (SX), 1300-nm (LX), or 1550-nm

fiber and uses SC, MT-RJ, or LC connectors. The Multimode SX

supports distances of up to 722 feet (220 m); the single-mode models

support distances of up to 40.4 miles (65 km).

User-selectable Link Propagation is available for Spanning-Tree

redundant network architectures as well as for connecting to SNMP

or other network-managed devices that monitor link availability.

A user-selectable override is provided to isolate the link detection

to a per-segment basis.

The converter’s UTP port uses a modular EIA/TIA 568 RJ-45

connector and supports Category 5 or higher wiring with distances

of up to 328 feet (100 m). Automatic polarity detection and correction

assists in network installation and maintenance.

Token Ring UTP/Fiber

For Token Ring LANs with fiber-to-copper conversions, these

models automatically sense and configure themselves to the network

ring speed. They also self-configure to attached devices through an

automatic sensing circuit.

The UTP port can attach to a workstation’s network interface card,

ring-in/ring-out port, or lobe. This converter can also support server

or workstation fiber attachments and fiber ring extensions.

Category 3, 4, and 5 wiring can be used. At 16 Mbps, Category 5

wiring can support distances of 492.1 feet (150 m). At 4 Mbps,

Category 5 wiring will support distances of 1604.4 feet (489 m). With

fiber, the converter supports 1.6 miles (2.6 km) using multimode fiber

and 12.4 miles (20 km) using single-mode fiber.

These models also test cable integrity in the network.

100-Mbps Fiber-to-Fiber Mode Converters

Multimode-to-Single-Mode converters connect to the network

over multimode fiber. But between Media Converters, they connect

with single-mode fiber to give you distances up to 36.1 miles

(58.1 km).

Multimode-to-Multimode versions extend your network up to

3.1 miles (5 km).

100-Mbps Fiber-to-Fiber Mode Converters support Token Ring,

Ethernet, and Fast Ethernet.

1000-Mbps Multimode-to-Single-Mode

1000-Mbps Multimode-to-Single-Mode converters connect

to the network over multimode fiber and extend the network with

single-mode fiber. They support single-mode distances up to 31.1
