Problems solved by technology

Although they are completely wavelength agnostic, they still have serious disadvantages
RSOA has limited modulation bandwidth (up to 2.5 GHz), and REAM suffers from extremely high inherent losses and requires optical amplifiers

Embodiment Construction

[0026] The present invention will now be described more fully with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey to those skilled in the art. convey the scope of the invention. In the drawings, like reference numerals indicate like elements.

[0027] figure 1 is a schematic block diagram of a system 100 capable of implementing the present invention. System 100 includes several TDM-PON links (not shown). Each TDM-PON link has two dedicated wavelengths for bidirectional transmission. By the cyclic nature of the wavelength multiplexers 120, 125, wavelength channels are transmitted through a single port 130, 135. The cyclic nature of the multiplexers 120, 125 is based on ...

Abstract

The present invention relates to a transceiver unit in a passive optical network (PON) for receiving an optical input signal and transmitting an amplitude modulated optical output signal. Furthermore, the invention relates to a method in a transceiver unit for receiving an optical input signal and transmitting an amplitude-modulated optical output signal.

Description

technical field [0001] The present invention relates to methods and apparatus for receiving an optical input signal and transmitting an optical output signal. Background technique [0002] Passive optical network PON is a point-to-multipoint optical network architecture. A PON may be, for example, a fiber-to-the-premises, fiber-to-the-curb, fiber-to-the-box, or fiber-to-the-building network. Unpowered splitters are used to enable a single fiber to serve multiple sites. [0003] The PON consists of an Optical Line Termination (OLT) at the central office CO of the service provider and a number of Optical Network Units (ONUs) near the end users. Compared to point-to-point architectures, PON configurations reduce the number and cost of fiber required. Downstream signals are transmitted to and upstream signals are received from premises sharing a single optical fiber using a multiple access protocol such as Time Division Multiple Access (TDMA) or Wavelength Division Multiplexi...
