Metro Optical Networks Market Beginning a Period of Long-Term Growth in 1999
Updated 8:04 AM ET August 30, 1999
Expected To Reach $1.2 Billion Worldwide In Five Years, According to Pioneer Consulting
CAMBRIDGE, Mass., Aug. 30 /PRNewswire/ -- According to a new report by Pioneer Consulting, Metro Optical
Networks: Metro DWDM and the New Public Network, the market for DWDM-based systems in metropolitan areas will exceed $1.17 billion by 2003, fueled by metro carrier requirements for flexible, scalable, high-bandwidth solutions. As
networks transition from traditional TDM-based services to packet-based IP services, current metro area infrastructures are often costly to upgrade and inefficient in handling bursty IP-based traffic. Metro optical network solutions utilize advancements in DWDM technology to provide city carriers with a variety of alternatives to pulling new fiber or stacking SONET rings to increase capacity.
A number of existing DWDM vendors have brought metro optical products to market in 1999, including Ciena, Nortel,
Ericsson, Lucent Technologies and Osicom, while a variety of start-ups including Astral Point, Chromatis Networks, New
Access Communications, and Optical Networks Inc., leverage innovations in both the telecom and datacom worlds to
optimize solutions for this complex market. Pioneer Consulting identified three emerging segments within the metro optical networks market:
1) Metro Core, in which DWDM solutions are employed to increase capacity between and among carrier central offices,
ISP hubs and IXC points of presence (POPs) within a metropolitan area. These solutions are aimed at increasing the capacity of existing fiber networks, while adding the flexibility associated with wavelength-based routing, restoration and provisioning of services.
2) Metro Access, an area today dominated by SONET or ATM-based access multiplexers and switches. This area of the
network interconnects major customers and aggregation points within a city network with central offices and network hubs.
Today the bandwidth available in the metro access network is quite limited, creating significant opportunities for vendors that create scalable, low-cost solutions with a degree of "transparency," or the ability to support many service protocols over the same common infrastructure and optical interfaces.
3) Enterprise DWDM, in which private networks utilize the capacity and transparency of DWDM to interconnect corporate
data centers, e-commerce sites, web server farms, and data warehouses for disaster recovery, data mirroring, and
metropolitan area private network applications.

"In 1999, announcements from Cable & Wireless USA, AOL, and Southern California Edison have indicated an emerging
robust market for metro optical networks," said Scott Clavenna, Principal Analyst at Pioneer Consulting and author of this report. "The challenge to the many vendors addressing this market is to devise solutions to the metro area bandwidth crises without adding another layer of complexity to an already multi-layered network. Key carrier demands include network simplification and integration, reliable optical layer management, and products that go beyond simple fiber expansion to include more flexible and rapid means of service provisioning."
Based on an analysis of demand generated at carrier central offices, ISP hubs, and CLEC POPs, Pioneer has determined
there exists a significant long- term addressable market for a range of metro optical network equipment, including metro core equipment for inter-facility interconnect, metro access equipment for hub-to-access node connectivity, and enterprise DWDM for intra- enterprise connectivity. Metro core will represent the largest share of this market, due both to the higher demand for capacity in this segment, but also because of the higher cost of the equipment associated with inter-office transport. Metro access represents a long-term growth market as vendors bring dynamic optical add-drop multiplexers to market that provide a transparent optical interface to carrier and enterprise access and aggregation equipment. This will encourage the simplification of networks, and the reduction of intermediary multiplexing equipment in metro area networks.
Over the forecast period, the global metro optical networks market is forecast to grow from a modest $154 million in 1999 to over $1,170 million in 2003.
