Product Specification
70 GHz Balanced Photodetector
BPDV3120R
PRODUCT FEATURES
70 GHz bandwidth guaranteed
Unsurpassed high-power capability
Detection of 64 Gbaud x-QAM signals
Integrated 50 Ω termination
Unique on-chip biasing network
APPLICATIONS
Transmission systems of 400 Gb/s
through 1 Tb/s
Coherent Test- & Measurement systems
Research- and Development systems
Microwave photonics
The balanced photodetector consists of two optimized 75 GHz, waveguide-integrated
photodiodes on one single chip. As a single balanced photodetector, this configuration ensures
an excellent uniformity of the paired photodiodes and is biased via integrated biasing network.
Due to optimized combination of waveguide and PD design, even at high optical powers, a
linear frequency response can be guaranteed. The integrated 50
Ω
termination allows an
excellent match of the electrical output signal. Tailored configurations are available, such as
BPDV dual pair -and quad sets, including connector customization and fiber matching to
enable coherent detection.

Accessories
Evaluation Kit
The kit serves as easy-to-use utility to characterize
the balanced photodetector under laboratory
conditions and contents of a printed circuit board
(PCB), four screws to establish removable
connectivity between photodetector and board, as
one DC cable to ensure the photodiode bias
voltage.
ORDERING INFORMATION
EVA-BPDV
Evaluation board for all balanced
detectors; includes 1x PCB, 1x DC cable set and 4x socket head screws 4-40 UNC
Photodetector Power Supply
We recommend usage of our
individually accessible photodetector
power supply (PPS), in particular for
optimized performance at high optical
input levels. As portable device it
provides stable biasing voltage supply
and a front display for review on
photocurrent.
ORDERING INFORMATION
PPS-03-B
Photodetector power supply for all balanced detectors; includes 2x PPS, 1x cable-set
B-type. The PPS is compatible with EVA-board (specified scheme applicable to RM
& RQ version). PPS units include 2x 1.5V batteries
