Broadband access and network capacity are now the top priority among K-12 IT leaders, according to the Consortium for School Networking's (CoSN) 2016 K-12 IT Leadership Survey. The fact that [...]

Optical fiber architecture was designed considering four technologies which focused on wavelength service to achieve accelerated deployment of an all-optical network. Arrayed waveguide grating provides accurate multiplexing and demultiplexing of optical signals. Acousto-optic tunable filter produces acoustic waves for wavelength selection. Multi-wavelength substrate fabrication enables matching of wavelength grids for multiplexing systems. Wavelength translation enables optical switching technology for payload transparency., How four technologies will accelerate deployment of optical network architectures. Significant advances in optical fiber components are accelerating carder interest in design and deployment requirements for the all-optical network. Initial [...]

Enabling optical services and lowering cost of operations are key Studies have shown that carriers spend on average two to four times more on network operations and management than on […]

SAN JOSE - Look out ATM, there's a new Ethernet guru in town. Salira Optical Network Systems was launched last week to develop products that would let carriers provision optical […]

Touch America's arrival on the long-haul fiber scene seems to have been achieved virtually under cover of darkness -- a conservative Big Sky utility quietly reborn with the instincts of [...]

Fiber optics is a much simpler technology than most people believe. It's not difficult, just different. In order to future proof your facility, begin installing fiber now. It makes economic [...]

On Fiber Communications increased its revenue by about 500% in 2002, in spite of the poor economy. The company was started in late 1999 with the support of venture capital. Recent acquisitions have increased earnings.

New technologies can transform the delivery of communications services--whether voice, data, wireline, wireless or content--and often spawn new business models. New services, however, necessitate integration of multiple technologies, devices and […]

The testing of the fiber optic components inside fiber optic data network system boxes is critical to the data network's overall performance. To ensure that new fiber optic networks perform […]

The market for synchronous optical network (Sonet) is growing at a robust pace. Telecommunication carriers are already taking advantage of Sonet technology in the installation of new fiber optic networks. Moreover, several are already implementing four-fiber OC-192 bidirectional line switched rings in their networks, which can accommodate repeated failures and continuous traffic transmission and reception. Some are already considering foregoing Sonet multiplexers and using dense wave division multiplexing or special routers to incorporate data traffic directly onto fiber., Despite all the talk about Sonet beginning to disappear, Sonet vendors are enjoying healthy growth and the carriers that are building new fiber optic networks are using the technology in [...]

Observers are hailing the recent merger announcement between Tellabs and Ciena as indicative of the increasing interest in optical networking and capacity-boosting dense wavelength division multiplexing (DWDM) technology. According to […]

SmartShip program outfits ships with LANs to reduce crew requirements The Navy is outfitting two more ships in its SmartShip program with fiber-optic LANs to support applications that eventually will […]

Wavelength division multiplexing (WDM) has become popular among carriers because it gives their fiber optic networks increased flexibility and reliability. WDM enables carriers to transmit standard fiber optic signals in different wavelengths. This allows carriers to increase the capabilities of their fiber infrastructures, which have almost been maximized, and optimize the benefits derived from deployment expenses., WDM allows carriers that are maxing out existing fiber to expand their infrastructure, and lets new carriers get the most for their deployment dollar. It can take awhile for some [...]
