Enabling service providers to cater to the demands for increasing bandwidth, ADC has announced that it has expanded its industry-leading PONy Express access transport platform with a new WDM-PON application. The PONy stands for “Passive Optical Network over wavelengths” and it’s the first transport platform to address the bottleneck that occurs in traditional optical access networks.

 

Without having to sacrifice or restrict bandwidth, PONy Express enables cost-effective access to business parks, campuses, and multi-dwelling unit/multi-tenant units, using a shared network. The solution can provide up to 1Gbps of dedicated, symmetrical bandwidth simultaneously for up to 16 customers. With the help of this solution, service providers can address multiple markets such as Fiber-To-The Building (FTTB) and Fiber-To-The-Curb (FTTC) with a single product.

 

Merging the best elements of private, point-to-point networks, security and dedicated bandwidth, with the best elements of traditional PON, the PONy Express WDM-PON Solution provides benefits such as coexistence with GPON to deliver residential and business services from the same fiber distribution cabinet; plug-and-play simplicity to reduce time-to-market and eliminate wavelength management issues; simplification of the upgrade path from GPON to higher bandwidth support for services such as IP HDTV; reuse of existing fiber distribution products to support the passive WDM-PON Plug-and-Play splitter module; reduced inventory costs by using "colorless" ONUs and OLT line cards; and service and bit rate upgrades without infrastructure changes.

 

PONy Express provides by combining a Wavelength-Division-Multiplexed Passive Optical Network (WDM-PON) Plug-and-Play Splitter in a fiber distribution cabinet. Instead of using a traditional Planar Lightwave Circuit (PLC) splitter, it uses an Arrayed Waveguide Grating (AWG) to multiplex and demultiplex wavelengths between the feeder fiber and the distribution fibers. Service providers can now insert a module into an existing GPON fiber distribution cabinet to support WDM-PON as AWG can be packaged in the same form factor as existing PLC splitters.

 

“Service providers worldwide are deploying PON, including GPON, to provide the bandwidth that consumers and enterprises demand,” said Jon Norton, vice president of Network Solutions (News - Alert) for ADC. “However, GPON can't meet long-term bandwidth requirements and WDM-PON provides a future-proof solution because its initial per-subscriber capacity of 100 Mbps is more than enough to support the most bandwidth-intensive applications and services.”
