Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Optical Transmit Power and Receive Sensitivity for Fiber Optic Connectors Table

Related Information

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.

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.
