Mitsubishi Electric to Sell 40Gbps DQPSK Quad PD Module
Tokyo, April 26, 2011 – Mitsubishi Electric Corporation (TOKYO: 6503) announced today the launch of a
compact, power-saving 40 giga-bits per second (Gbps) differential quadrature phase shift keying (DQPSK)
photodiode (PD) module for optical signal reception in transmission devices used to send large data volumes
between metropolitan areas. Mitsubishi Electric will launch the FU-387SPP commercially on June 1 and
expects to sell about 500 units per month.
The 40Gbps DQPSK Quad PD module integrates four photodiodes and two trans-impedance amplifiers in
one package, which will contribute to the downsizing of optical transmission equipment. The
energy-efficient device also features industry-leading low power consumption.
As optical communication networks transmit increasingly large amounts of data over long distances, needs
are mounting for higher transmission speeds and densely spaced wavelength division multiplexed channels
using multi-level formats such as DQPSK. Transmission devices commonly use two PD modules as a set,
each comprising two photodiodes and two trans-impedance amplifiers, but Mitsubishi Electric’s new module
combines these components in a single, smaller and integrated package.
Small size and low power consumption
- Four photodiodes and two trans-impedance amplifiers
integrated in an 11.0 x 14.9 x 6.7mm package
- Industry-leading low power consumption of 0.6W at 25
degrees Celsius
- 3.3V singularity voltage source of PD bias voltage (Vpd)
and supply voltage for trans-impedance amplifiers (Vcc)
Stable, high-quality signal for long-haul optical transmission
FU-387SPP
- New surface-illuminated photodiodes achieve low polarization dependent loss (PDL) of 0.1dB or less
1/2
- Bit error ratio is 1.3x10-8 (Q=14.9dB) even after transmission over several thousand kilometers
(OSNR=20dB/0.1nm, bit rate = 43Gbps)
Wide band detection range
- Wide detection range of 1520 – 1610 nm (C-band/L-band)
Other Features
Modulation format: DQPSK
PD responsivity: 0.85A/W (typical, 1550nm)
Input (Optical signals): LC connector with four-tape fiber featuring small bending loss
Output (RF signals): feedthrough with differential signal interface
In the near future, Mitsubishi Electric will market an optical signal-transmitting laser diode module to
operate on the opposite end of the line from the new FU-387SPP signal-reception module.
