Transmode iAccess addresses large-scale optical access with WDM-PON

Transmode Systems AB says unveiled its iAccess portfolio, which leverages its iWDM-PON offering (see “Transmode unveils iWDM-PON strategy”) to help service providers roll out Ethernet access networks for applications such as business Ethernet and mobile backhaul services.

The iAccess package combines a new compact, low-cost network interface device (NID) with the company's iWDM-PON hardware and Enlighten multi-layer network management system to provide what Transmode asserts is a low-cost, simple to install/configure/manage, and highly scalable approach to last mile Ethernet applications. The systems use a "remote port" architecture which makes all NIDs into extensions of the Ethernet Muxponder to which they are connected.

With the remote port architecture, the NID automatically takes device and service configuration data from the network when it is connected. This removes the need for a separate IP address for each NID, saving these sometimes scarce resources. Coupled with the colorless optical layer through the WDM-PON optics, iAccess creates a highly automated, simple to operate, and scalable system, according to Transmode. This is particularly true in comparison to other approaches that are either derived from more complex and expensive optical access platforms or are based on simple hardware designed for residential applications, the company adds.

The iAccess is thus ideally suited to the delivery of Ethernet-based services that need to scale to large volumes or where simplicity is key, Transmode continues. Installation procedures are quick and simple and Enlighten allows operators to create service templates to speed up deployment of multiple identical or similar services – enabling operators to minimize opex costs in addition to the lower initial capex costs.

Sten Nordell, Transmode's CTO, said, "The new iAccess solution is a great step forward in terms of simplifying and scaling Ethernet access networks while also enabling network operators to hit the right price points for these high volume services. We have created a real plug-and-play solution where the WDM-PON enabled NID is simply connected to the access fiber, powered up and then services are automatically created. This enables operators to quickly roll out new services with the right level of carrier class functionality such as Metro Ethernet Forum Carrier Ethernet 2.0 services."
