WDM-PON is emerging as a preferred long-term solution for scalable, high capacity access networks. The only way that service providers will be able to cost effectively scale to meet bandwidth requirements needed today and in the future will be to use fiber, passive plant, and the dedication of a wavelength per customer. The passive infrastructure will be required to achieve the OpEx cost efficiencies required, and to provide an easy means to achieve the high scalability, security, symmetrical bandwidth, and centralized architecture that will be needed.

Transmode’s unique iWDM-PON solution provides an open, standards-based approach that also helps operators avoid stranding assets and embrace future standards, while retaining the flexibility to expand the solution to include more cell site backhaul and ultimately FTTH as WDM-PON technology progresses further down the cost curve.

Transmode's iWDM-PON approach provides key benefits over TDM based PON and other WDM-PON approaches:

• Auto-Lambda technology - self tuning colorless optics that greatly lower cost and deployment/sparing complexity
• Highly flexible with operational Simplicity - Extending existing metro WDM into the access with the simplest self-tuning options to keep operations simple
• An open platform for any service or bandwidth per subscriber
• Investment protection - extending current WDM technology deeper into the access network with interworking with third party equipment
• Cost-effective and ideal for Enterprise, Mobile Backhaul and Fiber-to-the-curb/cabinet applications
• Differentiated capabilities - Dedicated, bi-directional and symmetrical bandwidth per subscriber which can be individually tailored and upgraded from FE to 10G or more
