Story by Patrick J. Sims and Pat Thompson of ADC

Service providers need not look too far in the past to find examples
of networks built without consideration for future technologies. While
our telecommunications forefathers may not have predicted today’s
broadband revolution as they designed the copper telephone network,
this legacy infrastructure still enabled a rough deployment of xDSL
technologies.

However,
the unpredictable performance of xDSL over load coils, splices, varying
gauges and conditions of the legacy copper network produced costly

SEPTEMBER 29, 2008 – PMC-Sierra Inc. has announced the availability of new GPON SoCs, which include the PAS7401 GPON ONT, the MSP7162 GPON Gateway, and the PAS5211 four-port GPON OLT. They feature PMC-Sierra’s GigaPASS architecture, which PMC-Sierra says is already deployed in more than 6 million PON devices and is enhanced for WT-156 compliance. These devices are PMC-Sierra’s second-generation GPON SoCs and include complete reference designs and software packages; all have proven interoperability with a wide-range of commercial GPON systems, according to the company.

“By partnering with PMC-Sierra to supply industry-leading GPON access equipment, Dasan is able to leverage PMC-Sierra’s extensive experience based on millions of FTTH field deployments,” said Dr. Steve Lee, vice president and head of R&D, Dasan Networks, Inc. “Our partnership enables us to offer high-performance, low-cost triple-play GPON systems based on field-proven, flexible platforms that Read the rest of this entry »

Alphion Corp. developer of communication systems, sub-systems, and integrated photonic components based on its proprietary QLight technology, today introduced the PON.ext Release 2 single-rack unit compact system. It is the company’s second-generation all-optical GPON extender. The new PON.ext unit allows carriers to extend network reach to 60 km, increase the number of end users up to 128, and reduce network operating expenditures, say company representatives. The transparent, all-optical system is fully compliant with the recently published ITU-T G.984.6 standard for GPON networks.

Migration to GPON: Practical considerations from the central office to the outside plant

August 26, 2008

(By Patrick J. Sims and Pat Thompson, ADC)

Practical considerations—based on informed decision-making—provide the foundation for a cost-effective transition between legacy and future access technologies.

Service providers need not look too far in the past to find examples of networks built without consideration for future technologies. While our telecommunications forefathers may not have predicted today’s broadband revolution as they designed the copper telephone network, this legacy infrastructure still enabled a rough deployment of xDSL technologies.

Just wanted to introduce myself

August 21, 2008

Hi all

My name is Travis and I’m one of the new fiber optic bloggers here at Fiber Optic Community. I haven’t really been working with fiber optics long but I really enjoy it. I’m usually in constant contact with the industry leaders and working on the distribution at the office. I do the catalogs for our company and I’m quick at finding an item.

I will be trying to help out here if you have any questions on categories for fiber optics. When I finish with the current catalog, I will be adding tutorials for you.

Thanks for visiting! – Travis  user – zgermanz

In the past 15 years, the telecommunication industry has been intensely focused on supplying more bandwidth to satisfy the ever-increasing consumer demand for high-speed internet, IPTV, gaming, and whatever other service that can be delivered satisfactorily over the network. The fallout has been a drastic increase in the power consumed at the central office (CO), along with a similarly drastic increase in the costs of supplying that power, both in terms of dollars and ultimately the far-reaching effects on the environment.

How much impact does the telecommunication industry’s drive for higher access speeds have on the planet? Is there a technology that can slow the trend of higher power for higher speeds?

Erlang To Always On

As has been thoroughly discussed elsewhere, the public switched telephone network (PSTN) was not originally engineered for Internet traffic. The PSTN capacity was based on a voice traffic density probability model as defined by the Erlang. In essence, for cost optimization, the telephone network was Read the rest of this entry »


Despite economics, WDM-PON remains in the mix

In its recent “PON and FTTH Subscribers” report, Infonetics Research noted that while GPON represents the most immediate growth opportunity, annual port shipments for the emerging WDM-PON segment are expected to grow at a 41% compound annual growth rate between 2007 and 2011. Much of this growth will come from the Asia-Pacific region, the analyst firm says, thanks to early WDM-PON adopters like Korea Telecom.

However, sentiment in Read the rest of this entry »


Suo Cable Net taps Alcatel-Lucent for Japanese GPON

Suo Cable Net, a Japanese cable-TV operator, has selected Alcatel-Lucent to design, integrate, and deploy a GPON. The new network, which will enable Suo Cable Net to begin rolling out high-speed Internet and video services this month, will be the first commercial GPON deployment in Japan, the systems house says.

With more than 10 million FTTH subscribers, Japan is one of the most advanced countries in terms of high-speed broadband coverage. While most initial deployments used BPON technology, GE-PON has been the technology of choice Read the rest of this entry »
