Description

The

D371-Type

Uncooled

Laser

Module

consists

of

a

laser

diode

coupled

to

a

single-mode

fiber

pigtail

.

The

device

is

available

in

a

standard,

8-pin

config-

uration

(see

Figure

1

and/or

Table

1)

and

is

ideal for

long-reach

(SONET)

and

other

high-speed

digital

applications

.

The

laser

diode

is

a narrow

linewidth

(<1

nm)

DFB-

MQW

single-mode

laser

and an

InGaAs

PIN

photo-

diode

back-facet

monitor

in

an

epoxy-free,

characteristics

listed

in

this

document

are

met

at

2

.0

mW

output

power

.

Higher-

or

lower-power

operation

is

possible

.

Under

conditions

of

a

fixed

pho-

todiode

current,

the

change

in

optical

output

is

typically

±0

.5

dB

over

an

operating

temperature

range

of

-40

°C

to

+85

°C

.

This

device

incorporates

the

new

Laser

2000

manufac-

turing

process developed

by

the

Optoelectronic

unit of

Agere

Systems

Inc

.

Laser

2000

is

a

low-cost

platform

that

targets

high-volume

manufacturing

and

tighter

product

distributions

on

all

optical

subassemblies

.

The

platform

incorporates

an

advanced

optical

design

that

is

produced on a

highly

automated

production

line

.

The

Laser

2000

platform

is

qualified for

the

central

office

and

uncontrolled

environments,

andcan

be

used

for

applications

requiring

high

performance

and

low

cost
