1. Overview

Thank you for purchasing PLANET FT-722 Fast Ethernet

Fiber-optic Media Converter. This converter is used to convert one type media signal to other type equivalent that allows two type segments connect easily, efficiently and inexpensively.

This converter can be used as a standalone unit or as a slide-in module to the 10

”/19” media chassis (up to 15 units) for a TP and Fiber combined networks at a central wiring closet. Please contact with your sales representative for more about the 19

” media chassis.

2. Model List

Your Fast Ethernet Converter comes with one of the following models.

Sxx represents Single-model optic interface in xx kilometers.

In the following sections, the term “ FT-722” indicates the product above, the term

“MM” and “SM” represents

Multi-mode and Single Mode fiber-optic mode.

3. Checklist

Your FT-722 carton should contain the following items:

5. Installing the Converter

Please follow these steps to install the converter:

•

Turn off the power of the device/station in a network to which the FT-722 will be attached

•

Ensure that there is no activity in the network

•

Attach MM fiber cable from the FT-722 to the MM fiber network. TX, RX must be paired at both ends

•

Attach SM fiber cable from the FT-722 to the SM fiber network. TX, RX must be paired at both ends.

•

Connect the 5VDC power adapter to the FT-722 and verify that the Power LED lights up.

•

Turn on the power of the device/station, the LNK /ACT

LEDs should light when all cables are attached.

Note: n To prevent from optic acceptor malfunction, check the both end including, connectors, cable type (MM/SM), and wiring distance before power on the Media Converter. n DIP-switch LFP is turn on by default, any broken link will cause the other end link down as well. To diagnose which end is broken, please turn off the LFP and power off/on the converter again. Please remains it on in normal operation.

DESCRIPTION

Blinks: when any FX packets transmitting and receiving

Lit: when Fiber connection is good

PWR Green Lit when +5VDC power detected

7. Cable Connection Parameter

Fast Ethernet 100Base-FX networks allow 512bit time delay between any two-node stations in a collision domain.

The overall bit time of Fiber wires and devices must be within

512bit time in segment. To extend the distance, you may use switch to break up a collision domain and extend the distance.

The limitations are as below:

Duplex Connection Limitation (max.)

Multi-Mode

MM Half Node to Node

Node to Switch

MM Full Node to Node

Node to Switch

Single-Mode

412 meters*

2 kilometers

SM Half Node to Node

Node to Switch 412 meters*

SM Full Node to Node

Node to Switch

Varies on model

Note: n In half-duplex mode, 412 meters is the maximum distance between two devices. To force both devices to full-duplex for optimal distance is strongly recommended.
