ATV10GC-J28 - Bookham Technology, Inc.

Data Sheet

The ATV10GC receiver consists of an avalanche photodiode,

alow-noise preamplifier, a MEMS variable optical attenuator

(VOA), and a precision NTC thermistor in a hermetic coplanar

package with a connectorized single-mode fiber pigtail.

Differential outputs are provided to improve noise rejection for

enhanced sensitivity.It has been optimised for use in 10Gb/s

metro or long-haul applications, either as a discrete device or

within a transponder, using NRZ modulation, with or without

FEC, at data rates up to 10.709Gb/s.

Features:

•High sensitivity, -26.5dBm typical

•Integrated MEMS VOA extends overload beyond

+10dBm

• Low capacitance high speed InGaAs APD

photodetector

• Supports FEC rates up to 10.709Gb/s

• Best in class power consumption, only 350mW

• Designed to exceed the environmental requirements

of Telcordia GR-468-CORE

• RoHS 5/6 compliant

Applications:

•Client or line side links

• DWDM TDM transponder applications
