Enterprise and MDU/MTU PON – Rack’em, But Don’t Stack’em

Posted by OJ Johnston on Tue, Apr 9, 2013 @ 17:04 PM

Currently, one of the challenges in deploying new, higher speed services to both enterprise customers as well as MDU/MTU customers is how to deliver these services using the least amount of space possible, while maintaining network flexibility and service quality.  M2 Optics’ recent release of the SplitLighttm High-Density Platform (HDP) enables unprecedented space savings and enhanced flexibility without sacrificing performance.

Size Matters!

As previously introduced in a recent article, the SplitLighttm HDP form-factor offers the most density available in a single RU for optical combiners/splitters (up to 192 each 1x2, 128 each 1x4, or 16 each 1x32) through its patent-pending, 3D architecture.  In addition to combiners/splitters, the SplitLighttm HDP can also house passive optical wavelength multiplexers (mux) and demultiplexers (demux).  In fact, it can house up to 16 of these mux/demuxes.  Furthermore, the SplitLighttm HDP can be configured to support both applications simultaneously within a single chassis.  As a result, in just 1RU of space, GPON, 10G GPON, WDM-PON, and network monitoring applications can all be supported from a single chassis.  Typically, this scenario would have required the following:

  • A patch panel with integrated tap for monitoring at the service demarcation point

  • GPON splitter shelf (3 or 4RUs) or wall mount cabinet combiners/splitters to split the signal from the feeder fiber onto the distribution fibers

  • WDM mux/demux, which may fit in the splitter shelf or may be a separate shelf (another 3 or 4 RUs)

By using the SplitLighttm HDP, all of these functions can be accomplished in a single chassis, reducing the required rack space from as many as 4-6 RUs or more down to just 1RU.  M2 accomplishes this by using MTP connectors to reduce the front panel space needed for connectors and the patent-pending 3D architecture of the system.

Doing More with Less – Future Proofing The Network

In today’s business environment, companies are being forced to do more with less. As previously mentioned, the SplitLighttm HDP allows companies to simultaneously tap signals for network monitoring, split signals to provide access via the GPON, and/or demux the wavelengths to provide access via the WDM-PON. Combining the functionality of multiple passive network elements into a single network element decreases the size without limiting flexibility. In addition, the SplitLighttm HDP can provide front panel, rear panel, or both, connectivity with customized labeling. The connectivity flexibility coupled with the 3D architecture of the SplitLighttm HDP, enables companies and service providers to have even more flexibility in future-proofing their networks.

Optimum Performance

M2 Optics’ SplitLighttm HDP uses low-loss components, including official US Conec MTP Elitetm connectors. Using bend-insensitve fiber and MTP Elite connectors coupled with M2 Optic’s comprehensive testing ensures the lowest possible loss across all connections while providing the size and functionality benefits previously mentioned. As a result, the SplitLighttm HDP surpasses the capabilities of all other solutions in the market.

The Ultimate Solution

Using a single chassis with the integrated taps for network monitoring, GPON combiners/splitters, and WDM-PON mux/demux provides unmatched flexibility and density in a single 1RU platform. Couple these attributes with high performance components and the SplitLighttm HDP delivers the ultimate solution for today’s high-bandwidth, enterprise and MDU/MTU PON networks.
