The rapidly increasing data traffic is placing ever greater demands on the capacity of communication systems. A research team now introduces a new amplifier that enables the transmission of ten times ...

Reflective Semiconductor Optical Amplifiers, also known as RSOAs, are high-performance, low-cost transceivers used for data amplification and modulation in radio over fiber systems, full-duplex optic ...

- 37.6 THz optical bandwidth achieved by combining 6 doped-fiber amplifier variants with lumped and distributed Raman-amplification to cover all of the low-loss transmission bands of silica fibers - ...

TOKYO--(BUSINESS WIRE)--NTT Corporation (President and CEO: Akira Shimada, “NTT”) has succeeded in the world’s fastest 1 optical transmission experiment of digital coherent 2 optical signals exceeding ...

A direct modulation bandwidth of 66 GHz has been achieved from two daisy-chained VCSELs, and the principle could be scaled up to reach over 100 GHz. An international research team has shown that a ...

Researchers have developed a new design of vertical-cavity surface-emitting laser (VCSEL) that demonstrates record-fast temporal bandwidth. Researchers at the George Washington University have ...

Handset manufacturers play an equally important role in this consumer equation by providing reliable, cost-effective handsets that are usable across multiple operating standards and market spaces. In ...

This is the fourth in a series of articles about FM transmission systems. The bandwidth of a commercial FM broadcast signal, depending on whether or not subcarriers are used, is about 260 kHz. This ...

The Traveling-Wave Tube (TWT) is a high-gain, low-noise, wide-bandwidth microwave amplifier. It is capable of gains greater than 40 dB with bandwidths exceeding an octave. (A bandwidth of 1 octave is ...

The amplifier developed by Chalmers researchers is compact, measuring just a few centimeters, yet it can process 10 times larger amounts of data per second than current optical communication systems.
