50 GHz Photodetector XPDV2320R PRODUCT BRIEF KEY FEATURES OVERVIEW High bandwidth with flat response The photodetector XPDV2320R is designed to exhibit an optimized frequency response in both, power and phase. It is ideally suited for OC-768/STM-256 long haul systems. The high power capability of up to 10 dBm allows for use of optical amplification at the detector input, and results in a high output voltage swing of up to 1V avoiding the need for electrical amplification. The photodetector is optimized for dual operations at 1310 nm as well as 1550 nm. Excellent pulse behavior Unsurpassed High-Power handling capability High responsivity Support of 1300 and 1550 nm Unique on-chip integrated bias network Well matched to 50 Ω APPLICATIONS DWDM Communication systems at 40 Gb/s (OC-768) and beyond Microwave Photonics of up to 60 GHz High-Speed Lightwave characterization A waveguide integrated pin diode provides an excellent linearity, high responsivity and a superior flatness of the RF response. An integrated biasing network guarantees a highly reliable component. 50 GHz Photodetector BLOCK DIAGRAM AND TYPICAL PERFORMANCE 100 nF * PD chip 250 0 200 50Ω 40 pF 30Ω 100 nF 1 V bias Response (mV) rf out Response (dB) optical connector 3 -3 -6 150 100 50 -9 2 * optional -12 GND 0 0 10 20 30 Frequency (GHz) 40 -50 50 0 50 Time (ps) 100 OPERATING CONDITIONS Parameter Symbol Operating Case Temperature Tcase Relative Humidity Wavelength Range Condition Min RH non condensing λ 1) Average Optical Input Power Range Popt Photodiode Reverse Voltage VPD Typ Max Unit 0 +75 °C 5 85 % 1300 1330 nm 1530 1620 nm 10 dBm 2.8 3.3 3.8 V Min Typ Max Unit OPTICAL AND ELECTRICAL SPECIFICATIONS 1 Parameter Symbol Condition R optimum polarization Photodiode DC Responsivity XPDV2320R @ 1310 nm XPDV2320R @ 1550 nm 0.45 A/W 0.65 A/W Polarization Dependent Loss XPDV2320R @ 1310 nm PDL XPDV2320R @ 1550 nm 0.4 0.7 dB 0.3 0.5 dB dB Optical Return Loss XPDV2320R @ 1310 nm ORL 24 XPDV2320R @ 1550 nm 27 3dB cut-off Frequency f3dB 2) Photodiode Dark Current Idark Tcase = 25°C 5 200 nA 3) 9 10 ps Pulse Width Notes: 45 50 GHz 1) λ = 1550 nm, Vbias = 2.8 V, T = 25°C 2) Measured using Agilent 50 GHz Lightwave component analyzer 3) Measured using Tektronix oscilloscope with 50 GHz sampling head Visit our website 1389 Moffett Park Drive Sunnyvale, CA 94089 Phone: +1 408-548-1000 Sales: +1 408-541-5690 Email: [email protected] www.finisar.com ©2014 Finisar Corporation.
