Analog

Operation

The

A370

Series

Laser

Module

has

the

capability

of

being

used

in

a wide

variety

of

analog

operations

.

These

may

include several

channels

of

pure

video

signals,

or

a

mix

of

video

signals with

digital

data

channels

riding

on

analog

carriers

.

It

is

difficult

to

prepare

a

single

battery

of

testing

conditions

that

will

satisfy

all

applications

.

The

following

table

contains

a

set

of

testing

conditions

that

Lucent

believes

will

give

a broad

indication

of

the

performance

of

the

A370

Series

Laser

Module

.

Please

contact

your

local Field

Application

Engineer

if

different

conditions

and

are

required

.

The

distortion

characteristics

are

measured

using

a

two-tone

test

.

The

frequencies

are
