Hub Collapse Cabinets
Many of Clearfield’s MSO customers have considered collapsing certain hub locations. The applications vary but the reason is the same. They want to save money. Electronics manufacturers have miniaturized the EDFA’s, transceivers, Power Supplies and Transponders to a point that they no longer need a physical building to house them. They can now reside in a small node case. This allows the MSO to eliminate the headaches and costs of maintaining a hut

Distribution Networks
When building a FTTH network, there are two basic architectures that you can choose from for your distribution segment:
1. Open architecture
2. Modular architecture
In an open architecture, the fiber cable is opened up to expose the individual fibers, either in a buffer tube or ribbon. These will be left in a splice tray in some type of enclosure such as a splice case, pedestal or terminal. This is a very inexpensive way to deploy fiber in a

Ruggedized Fiber and Extreme Duty Microduct
Sometimes the basics are what affect the outcome of an installation the most.
Here are some quick basic tips to use when installing pushable fiber into the ruggedized microduct, whether pre-connectorized or not. These techniques have been used to install single fiber, connectorized fiber and multi-fiber assemblies at distances in excess of 800 feet.
While the ruggedized fiber can be pushed in some instances, it typically can be pulled

Optical Circulators
The FTTH Expo recently concluded with much fanfare and optimism. Now we all get to go back to weekly tasks and as service providers often find out, the ‘blue sky’ of the conferences can fade into the clouds of reality.
However, there is a bright spot that may ‘make your day’ if you’re facing a fiber exhaust scenario with aging legacy optical transport equipment such as Async/SONET platforms with discrete WBO (Wideband Optics – either 1310

Is Plug and Play the Future of FTTH?

Brian Schrand
Clearfield Senior Member of Technical Staff
Service providers, consultants, engineering companies and contractors are all working together in building Fiber to the Home (FTTH) networks. The methods that they’re using to build and design these networks in most cases are based around a set of traditional standards.
The largest issue when using traditional methods to build a FTTH network is that they’re very labor
