Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that same or similar components in drawings are designated by the same reference numerals as far as possible even if they are shown in different drawings. For the purposes of clarity and simplicity, a detailed description of known functions and configurations incorporated herein will be omitted as it may make the subject matter of the present invention rather unclear.

[0032]FIG. 2 is a block diagram showing a structure of a wavelength division multiplexed passive optical network (WDM-PON) 200, an embodiment of the invention. The WDM-PON 200 includes a central office (CO) 210, a remote node (RN) 280 connected with the CO 210 through feeder fiber (FF) 270, and a plurality of optical network units (ONU) 310-1 to 310-N connected with the RN 280 through respective distribution fibers (DF) 300-1 to 300-N. The CO 210 performs non-intensity modulation for up...

Abstract

Disclosed are an optical transceiver and an passive optical network using the same. The optical transceiver includes a polarization splitter for splitting injected light input from an outside of the optical transceiver into a first polarization component and a second polarization component, a light injected transmitter for receiving the first polarization component and outputting an optical signal generated based on the first polarization component, and an optical receiver for detecting an electrical signal based on the second polarization component.

Description

CLAIM OF PRIORITY [0001] This application claims priority to an application entitled “Optical Transceiver and Passive Optical Network Using The same,” filed in the Korean Intellectual Property Office on Dec. 29, 2004 and assigned Serial No. 2004-115373, the contents of which are incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to an optical transceiver (TRX), and more particularly to an optical transceiver including a light injected transmitter and a passive optical network (PON) using the same. [0004] 2. Description of the Related Art [0005] Increasing interest in a wavelength division multiplexed passive optical network (WDM-PON) as a next generation subscriber network for providing future broadband communication services resulted in efforts to produce WDM-PON economically. Since WDM-PON allocates a separated wavelength to each subscriber, it requires a plurality of light sources and a wavelength di...
