In the distribution portion of the passive optical network (PON) for fiber-tothe-
premise (FTTP) architectures, the choice of fiber cabling – ribbon vs. loose
tube – can directly impact ease of installation and future performance. As is
usually the case in these networks, specific architectural characteristics and
particular applications may dictate the deployment of one type of cable over
“Ethernet Passive Optical Network” (hereafter called “EPON Network”)
comprises an Optical Line Terminal (OLT) system using its individual OLT to
interconnect with one or more specific groups of Optical Network Units (ONUs)
via a corresponding number of Passive Optical Distribution Networks (ODNs) to
construct a broadband point-to-multipoint access network between central office
and customer premises. A Service Provider can provide the broadband triple
play services by way of the EPON Network, such as high-speed Internet access,
VoIP and IPTV services.
FTTH Communications is an integrated provider of voice, video and
Internet services in Minneapolis. Delivering services to residential and
business customers on an all-fiber network, the FTTH Communications
business plan depends upon a combination of low costs, exceptional
service, and leading-edge technology to increase both the number of
subscribers and overall subscriber satisfaction.
After helping design and build passive optical networks (PON) for 10 towns since 1999, Vince
Smith has learned a thing or two about fiber to the premises (FTTP) projects. By the time he
was hired in 2003 by Texas-based NTS Communications as an outside plant engineer, Smith
had acquired good experience with different architectures as well as with products from
The PON (Passive Optical Network over wavelengths) Express 16 is the first transport platform
to use a Passive Optical Network (PON) architecture to break the access bottleneck. Using Dense
Wave Division Multiplexing (DWDM), the PON Express 16 provides cost-effective access to
business parks, campuses, and multi-dwelling unit/multi-tenant units over a shared network
infrastructure without sacrificing security or limiting bandwidth. Up to 16 customers can be
simultaneously connected with each having up to 1Gbps dedicated, symmetrical bandwidth.
Designing user interfaces nowadays is indispensably important. A well-designed user interface promotes users to complete their everyday tasks in a great extent, particularly users with special needs. Numerous guidelines have already been developed for designing user interfaces but because of the technical development, new challenges appear continuously, various ways of information seeking, publication and transmit evolve.
Những năm gần đây, việc gia tăng dung lƣợng mạng truyền dẫn cùng với việc phát triển
các ứng dụng và dịch vụ mới đến khách hàng đã tạo ra hiện tƣợng gọi là thắt cổ chai trong
mạng truy nhập. Không nghi ngờ gì nữa mạng quang là một giải pháp cần thiết và quan trọng
trong vấn đề truyền dẫn.
As the final touches are added to Gigabit Passive Optical Network (GPON)
standards and with next-generation GPON (N-GPON) standards already
underway, it should be clear to service providers that additional network
upgrades are imminent as demand for bandwidth continues to increase. Today’s
fiber-to-the-premise (FTTP) architectures, deployed with broadband PON (BPON)
technology, are meeting the needs of small business and residential customers,
but are they being constructed with easy upgradeability once bandwidth usage
As carriers begin deploying FTTX architectures, they are focusing a lot of
attention on the outside plant (OSP) segment. And why not? This architecture
presents many challenges with passive optical networking (PON) technology,
thousands of distribution lines and connections, power and distance concerns,
and so many other issues to address. Basically, the mindset is that if a problem is
going to surface during the FTTX deployment, it will likely happen downstream.
Passive Optical Network (PON) infrastructures deployed in fiber-to-the-premises (FTTP)
networks require numerous fiber connections to achieve the distribution of services to
multiple homes. Although splicing has its place in these systems, use of reliable anglepolished
connectors (APCs) provides numerous advantages in terms of overall network
flexibility, testing and troubleshooting.
Home Town Cable Plus is an integrated service provider operating in the city of Port St. Lucie as well
as in the county of St. Lucie in Florida. Just three years ago, the new company embarked upon its
plan to build a passive optical network (PON) to link homes and businesses in its service area to the
company data center. Home Town officially opened for business in September 2003 with a bundle
that includes standard POTS as well as alarm and monitoring services.
