The first challenge in providing fiber-based broadband services to businesses is, of course, the availability of fiber capacity.  Often, fiber routes run directly past a potential new customer, but all of the fibers are in use.  Obviously, this can be frustrating for a service provider, and may cause the valuable business customer to seek another solution.
In such a scenario, individual fibers within cables have all been utilized to haul traffic.  Splice closures in the outside plant may be near capacity.  At this point, a service provider will either  build new fiber or purchase expensive new electronics at each end of the fiber (or both). All Systems Broadband has carefully designed its passive components to offer another solution that leverages previous asset investments such as splice cases, and may often prove to be both more economical and offer a quick response to the opportunity.


Use WDM to Increase Fiber Capacity

Network 2The example illustrated to the left is the use of a CWDM device, such as ASB’s HiDT CWDM Module mounted in an “exhausted” fiber splice OSP closure.  The HiDT is one of the smallest form factor CWDM modules designed for the OSP environment.  The module may be mounted in an existing splice tray within the fiber splice closure using simple adapters or, alternatively, may be placed inside ASB’s small splice tray which is designed to fit in the largely unused “slack basket” area of the closure.  Mating a HiDT with a HiD4 CWDM module mounted in a high density shelf at the Head End allows the use of additional wavelengths on a fiber, easily increasing its capacity without additional fiber or OSP closures. 

Deploy an efficient Demarc Point

Once capacity issues are addressed, a service provider must bring the fiber into the customer’s premises quickly, efficiently, and securely.  Cramped telephone closets often present a challenge in terms of wall space and fiber management.  Business customers may want access to their fiber connections, providing them the flexibility to connect their own devices seamlessly across their entire network.  Increasingly, service providers may offer wavelength services as an economical solution to their customer’s needs.  The ability to provide for each of these requirements, as well as any additional needs, will impact a business customer’s buying decision.

FDE – Fiber Demarc Enhanced Access Box

When seeking to meet the diverse needs of a typical customer base, it is desirable to have products that provide maximum flexibility, while also being easy and quick to install.  It is these basic criteria that led to the creation of ASB’s line of indoor premises demarcation boxes.   The line includes boxes that use either a side-by-side or a layered demarcation arrangement.  Each style offers a range of features/functionality that allow service providers to quickly and easily deploy fiber-based services to both small and large businesses.

Getting bandwidth throughout the Business

With a greater push to bring higher bandwidth throughout a business location, service providers can often be challenged to find an efficient way to bring fiber inside of a building or throughout a campus.  The traditional approach has a technician install splice points (typically boxes or shelves)  throughout a building, followed by a separate install crew to run the fiber, and finally a splicer to hook it all together.  Network 3Such an approach is disruptive to the customer, involves a great deal of coordination, and can be expensive, impacting the profitability of the project.  ASB has designed a scheme in which pre-stubbed boxes may be deployed throughout a building or campus, the stubs are then run to a central collector terminal which is the only place that on-site splicing is required.  This approach minimizes the impact on a business’s operations, ensures a consistent deployment throughout, and reduces project costs by eliminating much of the labor involved in the more traditional approach, particularly those dollars spent on multiple splicers working throughout a building.  The result is a quick, efficient deployment that gets the project to providing revenue that much sooner, while also pleasing the important business customer.

Flexibly incorporate a variety of media connections


High Density Media Chassis – HDMC

Once inside a business environment, a service provider must adapt to existing infrastructure and/or provide for various types of fiber and copper connections. Flexibility is the keyword here. ASB’s solution, the High Density Multimedia Chassis (HDMC) provides high port density with the convenience of combining multiple media connections in a compact and highly configurable arrangement.

Products Featured in this Solution

HiDT CWDM Module

The innovative design of the HiDT housing offers improved port count and component capability creating design advantages for optical networks, while the small overall footprint allows for installation of two modules on a single splice tray, improving density in field deployment applications.

HiD4 CWDM Module

The miniature HiD4 footprint provides full functionality with up to 14 front facing LC/APC or LC/UPC ports and its mounting is compatible with LGX® shelves. At approximately 3″ deep, and half the width of a single LGX module, this package provides significantly improved port density when compared with conventional LGX cassettes.

4RU High Density Shelf

This shelf takes advantage of the industry-leading density of All Systems Broadband’s HiD4 cassette, packing much greater fiber capacity into a 4RU space.  Because the shelf utilizes industry-standard LGX® dimensioning, it  protects currently deployed LGX style assets, providing a side-by-side coexistence between standard-density LGX modules and the higher-density HiD4 cassette.

Universal Splice Tray (UST)

The All Systems Broadband Universal Splice / Component Trays have been designed to promote organized fiber management in a compact and efficient footprint. These versatile trays are designed to accept modules with unique flexible holders that provide placement for a wide variety of fusion and mechanical splice sleeves as well as passive components. Modules are also available for several sizes of passive multi-component housings. Sleeve and passive component modules can be mixed and matched on the tray for maximum flexibility in all field applications. Splice sleeve and passive component modules snap into the tray using patent-pending features that greatly reduce the risk of fibers being pinched or broken during module installation to the tray.

Fiber Demarc Enhanced AccessBox (FDE)

This box provides an efficient point of demarcation between a service providers fiber network, and that of the customer.  The side-by-side arrangement provides a lockable compartment in which the service provider may perform splicing of ribbon or loose tube fibers.  It is also designed to house various types of passive devices to allow the provision of wavelength and other advanced services.  The customer’s side of the box is also lockable, and provides an easy connection point for fibers in the customer’s own network.

High Density Multimedia Chassis (HDMC)

The HDMC chassis utilizes standard LGX dimensioning for its module/adapter panel slots. The system achieves high port density while providing multiple media connections in a compact package. Among the common connectors available are SC simplex, LC duplex, MPO/MTP, RJ45, F81, and more.
