Abstract

An optically fed point-of-presence apparatus is provided for a wireless network. The point of presence includes an electro-absorption modulator system which is in an optical path along which signals are conveyed respectively from/to a central access site. The point of presence includes a transmit antenna which is part of a transmission path which conveys signals from a first electrode arrangement of the electro-absorption modulator system to the transmit antenna for transmission to wireless terminals in the network. The point of presence also includes a receive antenna which is part of a reception path which conveys signals received from the wireless terminals at the second antenna to a second electrode arrangement of the electro absorption modulator system. The electro-absorption modulator system may be a split contact semiconductor modulator or may be formed of two devices, possibly integrated, at least one of which is an electro absorption modulator.
