CIP Technologies has a combined modulation and photodetection transducer capable of working at up to 60GHz.
The reflective electro-absorption modulator (R-EAM) meets customer needs for a low insertion loss, low drive voltage optical modulator in applications such as remote antennas and radio-over-fibre.
The product is particularly significant for those interested in the 28GHz LMDS (local multipoint distribution service) band, as well as experimental and research work in bands up to 60GHz.
The combination of modulation and photodetection in a single device means that both up and down links can be duplexed over a single fibre, leading to significant cost reductions and capacity improvements for network operators.
The device, 60G-R-EAM-1550, has an insertion loss of only 3.6dB and provides digital optical modulation at 50Gbit/s and RF modulation over its 60GHz bandwidth. It operates across the 1550 nm C-band with a low chirp parameter, and is intended for use with a laser diode source.
The photodetection capability is state of the art, providing 1.0 A/W responsivity and 43GHz bandwidth.
