Optelian Solutions

Telecom service providers have fiber spansin the access and interoffice that are at exhaust or near-exhaust conditions.The rapid growth of DSL and IPTV service offerings has placed severe strains onexisting fiber infrastructure in the access and interoffice. WDM, CWDM and DWDMprovide cost-effective and easy to install bandwidth solutions that take fulladvantage of existing fiber from very low growth fiber sections to extremelyhigh-growth sections. These systems can be either passive systems that acceptITU grid CWDM or DWDM wavelengths or active systems that accept nativewavelengths and convert or “transpond” them to the appropriate ITU gridwavelength. Reach extension products are often needed to extend the length of afiber span in the interoffice a sometimes in the access.

Optical Transport Solutions for Utilities

Utilities have long had fiber routes intheir networks for their own internal communications needs. Early utilityimplementations involved architectures utilizing Optical Ground Wire (OPGW).Some utilities have even sold excess capacity to other users. The bandwidthdemands of these utilities are increasing due to growth in supervisory controland data acquisition (SCADA) networks and other high bandwidth demands such asvideo surveillance. These increasing demands combined with low-count fiberroutes have created and ideal opportunity for technologies such as WDM, CWDMand DWDM. Some lengthy fiber entrance lengths to sub-stations or generatingfacilities can benefit from reach extension.
