| 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 1 Data Sheet Operating Characteristics Case Temperature = 25C unless otherwise specified Parameter Optical sensitivity BOL [1] [2] Symbol Sens Measurement Conditions 231-1 PRBS BER<10-12 VAPD=VM10 231-1 PRBS BER<10-12 VAPD=VM10 T=-5 to +75C DC - 6GHz Min Typ -26.5 Max -25.0 Unit dBm Sensitivity penalty EOL over temperature [1] [2] 0.75 1.0 dB Deviation from linear phase High frequency -3dB corner Low frequency -3dB corner Transimpedance gain Return loss Optical overload [2] [3] [4] [5] -10 7 7.5 +10 GHz fH fL TZ VOUT S22 PSAT VAPD=VM10 Small signal Small signal Peak-to-peak DC to 7.0GHz 0dB Attenuation VAPD=VM3 BER<10-12 With VOA actuated T=25C IAPD=10mA 40 1.1 1.6 600 -3 -1 2.3 700 -8 kHz k mV dB dBm Maximum output voltage6 Optical overload extension APD breakdown voltage APD breakdown voltage temperature coefficient Dark current Amplifier bias current Input current for output limiting VOA maximum attenuation VOA control voltage VOA current VOA power dissipation (continuous) VOA response time [8] [7] +13 25 0.030 0.045 40 0.061 100 75 95 0.5 20 30 5.5 6 33 5 9 7.2 65 10 0.15 0.4 10 dBm V V/C nA mA mA dB V mA mW ms dB dB k Vbr TVbr Id Icc IIn lim At 90% of Vbr Peak-to-peak Att VAtt lAtt PAtt Attenuation = 20dB Attenuation = 20dB Attenuation = 20dB From attenuation = 1dB to 20dB PDL PDL RTH VOA unbiased VOA biased T=25C Polarisation dependent loss Polarisation dependent loss Thermistor resistance Notes: [1] [2] [3] [4] [5] [6] [7] [8] 2 Optical Wavelength between 1525-1575nm.
