Optical Wireless Transport for xPON Networks: Satisfy Demand with a Shortcut to Broadband
PASSIVE OPTICAL NETWORKS (PON) HOLD GREAT POTENTIAL FOR WIDESPREAD DEPLOYMENT FOR FIBER TO THE HOME OR PREMISES (FTTH/P). THE ONLY THING HOLDING THEM BACK IS FIBER DEPLOYMENT DELAYS. WHAT IF THERE WERE A WAY TO BYPASS FIBER AND DEPLOY PONS WIRELESSLY?
workers are telecommuting. People watch multiple HDTV channels. Online games demand lightening fast reactiv- ity. Uploading and downloading mul- timedia files. Social and collaboration sites create more demand. Traditional networks simply cannot keep up with the requirements of today’s broadband customer. Service providers are struggling
T
to provide converged or triple-play services to attract and keep customers. Consumers are no longer satisfied with POTS and copper-based broadband, they have evolved and the network must evolve with them. Fiber is the next logical step in this evolution but operators need a cost effective solution to remain competitive. As a result, many service providers are
looking to passive optical networks or PONs which allow them to deliver fiber to the home (FTTH) cost effectively. Gi- gabit PON or GPON (and GEPON) uses a passive, point-to-multipoint architec- ture that allows a single strand of fiber to service many end users without the need for active switches or routers thus reduc- ing both cost and complexity. A GPON network consists of an a cen-
tral server or optical line terminal (OLT) in a hub location that splits a single strand of fiber between up to 128 (32 or

he way today’s consumers use the Internet has created enormous demand for high bandwidth connections. Many
64) customers using low cost customer premise equipment (CPE) called an ONT or ONU. It’s fully optical architecture delivers 2.5 Gbps of downstream capacity and 1.25 Gbps upstream and because it’s optical GPON provides the low latency, low jitter connections necessary to service voice and gaming apps. An ideal application for the GPON
architecture is high-end multiple dwelling units or MDU’s. Adding fiber connectivity to the offering helps developments both new and old to attract a sophisticated, tech-savvy clientele willing to pay more for modern amenities. Despite the benefits of the xPON architecture, there can still be many challenges and delays when rolling out a high speed network to a MDU. One of the most challenging is providing the connection between the OLT and the customer location. The quality of this con- nection is critical to the GPON standard. It must provide very high bandwidth (2.5 Gbps) and very low latency that only an optical connection can deliver. Up until now, the only solution has
been to run fiber between the two loca- tions. Running fiber has always been an expensive and time consuming proposi- tion that is only getting worse. However, there is now a wireless solution that provides the speed and quality of an optical connection without the cost and delay of laying fiber. SONAbeam optical wireless sytems offer all the benefits of fiber but can be installed in less than a day at distances of up to 1 kilometre. For
service providers and network operators this means a dramatically reduced time to revenue and return on investment. SONAbeam eliminates the substantial
costs of digging up streets and sidewalks required to install fiber while also avoid- ing recurring costs. Unlike other wireless solutions, the SONAbeam is immune to electro-magnetic (EM) and radio- frequency (RF) interference which means no licensing is required.
