The product is particularly significant for those interested in the 28 GHz LMDS (Local Multipoint Distribution Service) band, as well as experimental and research work in bands up to 60 GHz. 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 3.6 dB and provides digital optical modulation at 50 Gbit/s and RF modulation over its 60 GHz 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 43 GHz bandwidth.
