Introduction

This document provides the optical transmit power and receive sensitivity for fiber optic connectors on various router and switch interfaces. These numbers can be used in the calculations explained in the "Evaluating the Power Budget" section of the ATM Interface Processor (AIP) documentation. (When you view the AIP documentation, use your browser's "Find" feature to locate the desired section of the document.)

Note: The AIP documentation uses the terms PT (minimum transmitter power) and PR (minimum receiver sensitivity). In this document, the "transmit dBm min" column equals PT and the "receive dBm min" column equals PR.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

This document is not restricted to specific software and hardware versions.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Note: 

1 All GBICs use Class 1 lasers, even with multimode fiber. A Mode Conditioning Cable (MCC) is required when using multimode fiber with any LX/LH GBIC. All of these GBICs have a minimum cable length of two meters.
