Title:
スプリットの数および帯域幅を増加するためのキャリア・クラスのWDMPONのためのシステムおよび装置
Document Type and Number:
Japanese Patent JP2007524305
Kind Code:
A
Abstract:
A Passive Optical Network (PON) is provided with enhance split capability and bandwidth by employing Wavelength Division Multiplexer (WDM) elements in combination with optical couplers at optical distribution nodes (ODN) intermediate a local exchange office node and a customer node. The local exchange office node transmitting and receiving signals from a single optical fiber through a WDM and each customer node connected to one leg of an optical coupler in the ODN with a WDM for received and transmitted signals. Upstream transmission is accomplished with a single wavelength.
