UltraSpan™ Power Booster

PRODUCT BRIEF
KEY FEATURES

OVERVIEW

t Works with any existing booster
amplifier

Finisar's UltraSpan™ Power Booster is a unique high output power EDFA designed to boost
the launch power into the transmission fiber up to 26 dBm. This high output power is critical
in applications requiring an improved optical signal to noise ratio (OSNR), such as long
repeaterless links, long span masking in multi-span links, and high capacity systems. The
product is packaged in a 1RU rack-mountable network-ready unit, including built-in GUI and
SNMP communications, and can thus be operated as a fully independent network element.

t Class 1M* laser safety classification
t Detects fiber link disruptions up to a
few tens of kilometersfrom the unit,
and open connectors
t Optional high power connector
cover switch safety mechanism
t Optional amplification of the
optical supervisory channel (OSC),
e.g. 1510 nm
t Gain flattening of less than 1 dB
t Optional pre-tilt for SRS
compensation
t State-of-the-art transient suppression
t 1RU network-ready rack-mountable
unit
t Supports SNMP v2/v3
communication protocol

The Power Booster is designed to be deployed in conjunction with existing booster amplifiers.
Thus, it provides relatively low gain and high output power as required for boosting the output
of existing booster amplifiers from 17-20 dBm to the range of 23-26 dBm. As the product is fully
compatible with existing booster amplifiers, it can easily and rapidly be integrated into any
existing design to allow the system to support OSNR critical applications requiring high launch
power.
Using patented automatic power reduction mechanisms, the Power Booster is classified as a
Class 1M* laser product, even though it typically provides output power above 21 dBm. The
amplifier contains three parallel fully independent eye safety mechanisms that shut down the
amplifier in case of a fiber link disruption, including open connectors (PC or APC) or broken
fiber, even at a distance of a few tens of kilometers from the unit.
The Power Booster can optionally be provided in a high gain configuration to replace existing
booster amplifiers, as well as a module for integration on a line card.

remote locations, disaster recovery
t Security-sensitive applications
t Traversing challenging spans within
multi-spans links
tImproving OSNR in long-haul and
ultra-long haul links
t 40 Gb/s and 100 Gb/s transmission
and/or increasing channel count to
80+ WDM channels
