Title:
MODULE HAVING TWO BI-DIRECTIONAL OPTICAL TRANSCEIVERS
Document Type and Number:
WIPO Patent Application WO2004075422
Kind Code:
A3
Abstract:
Bi-directional communications modules (330, 308) are configured for propagating transmission and reception of optical data along each of dual optical cables (306, 308). The modules generally include: a first transmitter (410) configured for transmitting data on a first wavelength channel onto a first optical fiber; a first receiver (414) configured for receiving data on a second wavelength channel from the first optical fiber; a second transmitter (412) configured for transmitting data on the second wavelength channel onto a second optical fiber; and a second receiver (416) configured for receiving data on the first wavelength channel from the second optical fiber. By changing the use of the dual optical cables from unidirectional traffic to bi-directional traffic, the modules thereby double the data transmission capacity of the cables without changing the size of the cables or transceiver modules or requiring the installation of new cables.
