PA-A6 ATM Port Adapter Installation and Configuration

OL-2672-05

Chapter 1 Overview

Cables and Connectors

Figure 1-8 Simplex SC Connector

An appropriate fiber-optic cable must be used to connect the PA-A6 to the ATM switch or circuit.

Single-mode and multimode cables should perform to the specifications listed in Table 1-4.

Note A single fiber link should not mix 62.5-micron and 50-micron cable.

T3 and E3 Cables and Connectors

The PA-A6-T3 and PA-A6-E3 port adapters use a 75-ohm coaxial interface cable to connect your router

to an ATM T3 or E3 network. The coaxial cables (Figure 1-9) conform to EIA/TIA-612 and

EIA/TIA-613 specifications.
