Overview

Raman technology for optical signal amplification, used in large

capacity digital communication and long-haul broadband DWDM

networks.

These modules extend the single span reach by at least 50 km

in comparison to the conventional EDFA type amplifiers. Raman

amplifiers also improve the Optical-Signal-to-Noise-Ratio (OSNR)

in amplified long-haul networks because they do not introduce

noise whereas typical EDFA amplifiers have a nominal noise figure

of about 5.5 dB.

The EM1600-OAR family consists of 3 modules differentiated by

maximum gain over G652 fiber (10, 12 and 15 dB).

As an example: If we need to transmit 10Gbps signals over a 200

km distance crossing the sea or a desert, without the possibility to

place a signal regeneration device in the middle, the only way to

reach the other side is by means of the Raman technology.

The EM1600-OAR family provides a flat response for the entire C-

band (1529-1564 nm). Other wavelength ranges (such as

L-band) are provided on customer request.

management and provide power monitoring on the amplified

optical signal as well as on the condition of the internal pumps.

EM1600-OAR incorporates parallel, independent eye-safety

mechanisms that shutdown the amplifier in the following cases:

1.

Fiber

breakdown,

open

connectors

(including APC), or broken fiber even at long

distances from the amplifier.

2.

High reflection power which may be caused

by bad connection or other problems in the

transmission fiber

3.

Pump high temperature that may be caused

by an internal problem

4.

Module high temperature that may be

caused by an internal or system problem

This unique and comprehensive safety mechanism of the EM1600-

OAR module is extremely important due to the Raman amplifier’s

high power light and power consumption.

Each EM1600-OAR amplifier module occupies 2“long”slots so that

it can be installed only in LD1600 or LD400L chassis type.
