Abstract

A bidirectional interface for multimode optical fiber includes a receive/transmit optical fiber port operable to connect to a multimode optical fiber, a wavelength separating module in communication with the receive/transmit optical fiber port, an optical receiver module in communication with the wavelength separating module and configured to receive optical signals at a first wavelength via the wavelength separating module and the receive/transmit optical fiber port, and an optical transmit module in communication with the wavelength separating module and configured to transmit at a second wavelength via the wavelength separating module and the receive/transmit optical fiber port.
