Introduction

This guide describes the Bay Networks 10BASE-FL (fiber link)
and single-mode fiber media adapters for the BayStack
10BASE-T Hubs, and provides instructions for installing,
connecting, and configuring the adapters in the hub.

Each BayStack fiber media adapter provides one nonredundant
single- or multimode fiber port for flexible backbone
connectivity to your BayStack 10BASE-T Hub. Both adapters
employ 10BASE-FL signaling technology.

The BayStack 10BASE-T Hub provides two Media Adapter
LEDs to indicate the status of the hub media adapter ports A and
B. For more information about interpreting media adapter LEDs,
refer to Chapter 1, “Quick Reference Information,” in

BayStack 10BASE-T Hubs

.

This guide contains the following sections:

• BayStack 10BASE-FL Media Adapter

• BayStack Single Mode Fiber Media Adapter

• Fiber Optic Cable Length Limitations

• Installing a Media Adapter in a BayStack Hub

BayStack 10BASE-FL Media Adapter

The BayStack 10BASE-FL Media Adapter is a modular
10BASE-FL fiber link port. It is designed to be installed in either
media adapter slot of a BayStack 10BASE-T Hub.

The port is compatible with the IEEE 802.3 10BASE-FL
specification for Ethernet running over 62.5/125 µm or 50/125
