ETC ATV10GC-J57

Data Sheet
10Gb/s surface mount coplanar APD
preamp receiver with integrated MEMS VOA
ATV10GC
The ATV10GC receiver consists of an avalanche photodiode,
a low-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
