Mitsubishi to Sell 40Gbps DQPSK Quad PD Module


Mitsubishi Electric 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 plans to 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 a single package (11.0 x 14.9 x 6.7mm), which will allow for more compact designs of optical transmission equipment. The device is also energy efficient (0.6W at 25 degrees Celsius.)



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.

Other features include:

- 3.3V singularity voltage source of PD bias voltage (Vpd) and supply voltage for trans-impedance amplifiers (Vcc)
- New surface-illuminated photodiodes achieve low polarization dependent loss (PDL) of 0.1dB or less
- 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 detection range of 1520 - 1610 nm (C-band/L-band)
- 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

Mitsubishi Electric said that in the near future, the company would also 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.
