This Frost & Sullivan research service on Advanced Technologies for Optical Networks provides an overview of optical switching technologies such as OPS, OBS, and OCS, and PONs technologies such as EPON, BPON, and GPON. It details the competitive landscape and includes major technology, market drivers, challenges for OBS and PONs, and the analysis of adoption factors. Frost & Sullivan's expert analysts thoroughly identify the need, evaluate the benefits, and analyze the developments of optical switching technologies and PONs.
Technology Overview
Increasing Data Traffic Aids the Development of Advanced Technologies for Optical Networks
The recent years have witnessed a phenomenal increase in the quantity of information exchanged across the globe. Due credit has to be given to the Internet, which is used for several applications including e-mails, online shopping, and exchange of business and personal information. "The Internet has been exponentially increasing data traffic during the past decade despite occasional glitches in the telecommunications industry," notes the analyst of this research service. "This upsurge in data traffic can also be linked to the demand from the access network side such as the broadband access from both wireless and wire-line."
Furthermore, IP-based services such as IPTV, online gaming, video telephony, and online movie streaming, requiring high bandwidth, are also complementing the growth of data traffic. Hence, telecommunications networks, gearing up to meet increasing demands for bandwidth, need advanced technologies such as optical burst switching (OBS), optical packet switching (OPS), gigabit passive optical networks (GPON) and Ethernet passive optical networks (EPON) for optical networks.
Developments in Optical Switching Technologies and Passive Optical Networks Present a Wide Array of Optical Network Solutions
Several optical switching technologies such as wavelength routing or optical circuit switching (OCS), OPS, and OBS are being researched and developed. While OPS seems to be the best solution on paper, OCS does not quite cope with the need for future optical networks in spite of having the ability of being deployed sooner than both OPS and OBS. On the other hand, OBS seems to be heading toward commercialization overcoming its barriers and hurdles.
While conventional approaches such as synchronous digital hierarchy (SDH) and Ethernet are point-to-point, PON is a point-to-multipoint network. "With the capability to provide significant bandwidth when compared to that of a copper-based network, PON intends to offer the bandwidth capacity of optical fiber that is competitively priced, with a copper access network," cites the analyst. It also offers a choice of three standards: Bandwidth PON (BPON), GPON, and EPON. BPON and GPON are based on the International Telecommunication Union (ITU-T), whereas EPON is governed by the Institute for Electrical and Electronics Engineers (IEEE). Further innovations and developments in the areas of optical switching technologies and passive optical networks can help optical networks effectively handle the data networks of future generations.
