Cutting Copper Good For Fiber Optic Industry?

Remember when cable companies lined our streets and installed miles and miles of cable to connect us to what is now a standard in each household? Cable TV! Now it is happening again but this time it is the phone companies. Yes, phone companies are beginning to cut the copper to each home in America and replacing it with optic fiber.

One news source reports:

“When Henry Powderly II ordered Verizon Communications Inc.’s FiOS fiber-optic service, he knew he was about to be connected to the future of telecommunications.

He also got unplugged from its past. Which meant that while Powderly was gaining features, he was losing some telecommunications options.

Verizon’s installer - without warning, Powderly says - removed the copper wires that used to carry his phone calls. For most of the world, copper still links homes and businesses, as it has for a century.

Verizon’s new high-bandwidth fiber lines are fully capable of carrying not only calls but also Internet data and television with room to grow. But once the copper is pulled, it’s difficult to switch back to the traditional phone system or less expensive Digital Subscriber Line service. And Verizon isn’t required, in most instances, to lease fiber to rival phone companies, as it is with the copper infrastructure.”

As reported above the copper infrastructure will one day be replaced by a more efficient more powerful “fiber line system”. What a boon for the fiber optics industry!

The article continues:

“The New York phone company has made it clear its entire network is going to fiber-optics. Verizon has decided to spend $23 billion to make fiber available to 18 million homes by 2010. Network maintenance savings could top $1 billion a year, Verizon said.”

While AT&T Inc. and Qwest Communications International Inc. are also retiring their copper networks, they’re not touching the so-called “last mile” of copper wiring that runs from each customer’s dwelling to the central office where other lines aggregate. Laying fiber, a robust pipeline, through the last mile is much more expensive because each line goes to a particular home or business.

Verizon is taking the pricey route because it believes fiber offers a superior service that will lure customers away from cable operators, who now offer telephone service in addition to television and high-speed Internet.”

All in the fiber optic industry will benefit by the transition from a copper based infrastructure to a optic fiber infrastructure at the residential level! Just a bit of good news we thought we would share. We will keep you posted.

Precision Mating Adapters

Precision Fiber Products Optical Connector Mating Adapters / Hybrid Mating Adapters were designed to meet: JIS C5973, NTT, IEC, TIA, and Telcordia standards.

Features:

  • Competitive pricing and in stock
  • FC Narrow Key and Wide Key Options
  • High reliability
  • Very stable
  • Singlemode performance rated
  • Ceramic and Bronze sleeves available

About Insertion Loss:

Insertion loss is a measurement of the light lost as it
passes through two connectors aligned with a mating adapter.
Excess light loss generally comes from the fiber cores not being
aligned. This mis-alignment can be caused by the connector
ferrules or the mating adapter Ceramic / Brass sleeve if the
mechanical tolerances are not controlled.

Precision APC Connectors

Precision APC connectors from Precision Fiber Products, Inc. were designed to reduce reflection and at the same time minimize insertion loss through precise control of ferrule endface angle and connector key error.

Features:

  • Excellent Backreflection - 70dB typical
  • Low Insertion Loss: - 0.12dB typical
  • 125, 125.5, 126 and 127 micron ferrule options
  • Cone or Step ferrule Options
  • Pre-Assembled for ease of manufacturing
  • Accommodates 0.9, 2.0 and 3.0mm Fiber
  • Competitive pricing and in stock

About APC Connectors

APC connectors have been developed for high bandwidth
systems wherelow reflection is critical. This is achieved by
creating an angle on the connector ferrule endface. Accurate
ferrule endface and connector key error is critical to maintain
low reflection and low insertion loss.

Precision Tune PM Connectors

Precision Fiber’s Precision Tune connector is a breakthrough in connector designs. Specifically designed for PM (Polarization Maintaining) assemblies and devices.

FC PM Connector FC/APC PM Connector SC PM ConnectorFeatures:

  • High and consistent extinction ratios: -27 to -30dB typical
  • Low Insertion Loss: < -0.2dB typical
  • 80, 125, 125.5, 126 and 127 micron ferrule options
  • Narrow and Wide Key Options, TIA compliant
  • Pre-Assembled for ease of manufacturing
  • Accommodates 0.9, 2.0 and 3.0mm Fiber
  • Competitive pricing and in stock

About PM Fiber

Polarization Maintaining fiber has been developed for
applications requiring the light to maintain it’s polarization as
it propagates through the fiber. This is done with Stress
applying members within the fiber that create two orthogonal (90
degree) axes through the core where the light signal travels.
Proper alignment to the light source and alignment of the fiber
in the connector with respect to the connector key is critical to
maintain polarization.
