Upgrade Telecommunication Services Cost-Effectively through Increasing Optical Fiber Capacity by Using Double-Density CWDM Transceivers

LOS ANGELES, Sept. 16, 2015 /PRNewswire/ -- Optowiz, a Korea-based optical network component manufacturing company, announced today a sales agreement with US-based Terraphotonics System Corporation (headquartered in Woodland Hills, CA) for the sales and distribution of its popular double-density SFP transceivers in the optical communication system technology offering. Dr. KJ Yang, CEO of Optowiz, announced the sales co-op agreement with Terraphotonics's international marketing executive, Adib Sharif, to represent Optowiz's double-density transceivers in the North American and Middle Eastern regions.  "Our business agreement with Optowiz in high-density optical transceiver products including 2WL SFPs will enable telecommunication service providers to increase their customers via doubling their fiber capacity by simply replacing their old conventional 1WL SFP TRx with this new 2WL SFPs without any additional change in device or equipment on their present optical communication operations architecture. That's the beauty of these 2WL double-density SFPs from Optowiz," according to Mr. Sharif.  The 2WL SFP users could double the effective fiber cable capacity without investment of any new fiber optic cables, adds Sharif.

Over the past decade, fiber optic communication has revolutionized the telecommunications industry. Specifically, optical communication over fiber has enabled multiplexing of multiple signal transmissions together over one or paired strand of fiber by Coarse Wavelength Division Multiplexing (CWDM) technology, thereby increasing fiber capacity significantly. The wavelengths used with CWDM implementations are defined by the ITU-T G.694.2, qualifying 18 wavelengths (channels) from 1270nm to 1610nm with a 20nm channel spacing.

Facing ever-increasing demand for telecommunication and data delivery services from end users, service providers continue to upgrade their WDM optical network infrastructure while attempting to reduce the cost of their services. In the vein of infrastructure investment cost reduction, network component companies, working closely with service providers, have been improving some parts of CWDM technologies that are designed to extend the use of existing investment in optical fibers by way of producing dual–density CWDM transceivers. Optowiz is now producing and selling such dual-density CWDM transceivers.  These dual-density CWDM transceivers make possible the use of service providers' existing investment in optical fiber communication systems without any change in their operational architecture or equipment except for updating their currently-deployed CWDM transceivers. Existing transceivers are single wavelength (1WL or single density), but Optowiz's new transceiver is double wavelengths (2WL or double density).  Each of conventional 18 CWDM transceivers – typically 16 CWDM wavelengths/channels are used– transmits or receives signals at its entire 20nm spectrum, but Optowiz divides this 20nm space into two high-band and low-band spectrum (called 2WL SFP) – all within the ITU-standard 20nm CWDM channel spacing.  Hence, each Optowiz 2WL SFP is equivalent to single 1WL conventional SFP, permitting the use of two transceivers over the single CWDM wavelength, effectively doubling the fiber capacity. 

Yang has emphasized that Optowiz's 2WL TRx offers a new method of transmitting data on each of the 18 common CWDM channels by dividing each individual CWDM 20nm spaced channels into high-band and low-band and that the 2WL SFP is designed to transmit data on one sub-band (low-band) of each CWDM wavelength while receiving the data on the other sub-band (high-band).  "This 2WL double-density SFP product is an inexpensive way of overcoming the capacity limits of optical fiber cables at the existing CWDM deployment operations as this technology creates 36 channels out of 18 CWDM channels," Dr. Yang adds. Optowiz released this double-density SFP to Korea's largest wireless carrier including many CWDM deployment sites. Leveraging over 10 years of solid business record as a key optical fiber communications component supplier in Korea, Optowiz is well positioned to service regional or national broadband service providers in the North Americas that currently lease fibers targeting for greater and more efficient utilization of CWDM-based data transport.  For product applications and spec, please contact Solla Park at +82 31 708 2836 (email her at [email protected]) – for Asian customers or Donald Yu at 714.519.4943 (email him at [email protected]) – for European and American customers.
