Transmission Access & Infrastructure
Imagine test tools that actually help you deliver services with speed and quality. Imagine if you could completely integrate operational efficiencies, eliminate silos and make every component of your deployment, turn-up and monitoring part of one tightly woven fabric. Well now you can.

FTTx ACCESS NETWORKS
FTTA, RRH and DAS: The New Wireless Network Extension
Even with additional spectrum and the introduction of long-term evolution (LTE) networks, there are geographical areas in mobile networks where demand is projected to exceed the capacity provided by the macro layer.
To expand their networks to other hard-to-reach locations, wireless providers are turning to the deployment of alternative infrastructures, like remote radio heads (RRH), distributed antenna systems (DAS) and other small-cell alternatives, most of which are fiber-based
Deploy faster, more reliable FTTH networks
With bandwidth demand growing faster than revenues, operators are boosting network capacity by rapidly shifting to FTTx. In a context of high pressure on cost and decreasing level of optical expertise in the field, FTTx/PON network testing is a necessity, and this, throughout all stages of the network lifecycle. This solution provides network operators with the expert testing knowledge, tools and environment they need to bridge the OPEX gap created by the increased bandwidth demand. With field-proven methods and procedures, smart and integrated test solutions and cloud-based data management, FTTH networks can now be deployed reliably and cost-effectively.
Multiplay Services Testing
Testing the quality of the optical link and copper pairs to assess the performance of the Ethernet and xDSLservices in the access network are mandatory steps to ensure that the physical layer can handle proper IP services delivery, but it doesn’t end there. Ensuring the quality and stability of video, voice and data components is the key objective of all service providers to ultimately bring the best quality of experience (QoE) to their customers.
As Ethernet is making headway into service providers’ networks, Carrier Ethernet testing becomes essential. With its additional operation, administration and maintenance capabilities, Ethernet can now be viewed as a carrier-grade networking technology. To deliver carrier-grade Ethernet, network service providers can implement Ethernet-over-SONET/SDH and leverage their existing assets while delivering new services. Or, they can implement a connection-oriented Ethernet access link that will provide them with a network that is as manageable as SONET/SDH, but with the cost-efficiency of Ethernet.
Packet Optical Transport—A Viable Solution to Network Expansion
Packet optical transport (POT) networks are optical super-highways that use the most advanced technological enablers, from reconfigurable optical add/drop multiplexers (ROADMs) to amplifiers—and from very high bit rates to dense wavelength-division multiplexers (DWDMs).
The need to shift from time-domain multiplexing (TDM)-based networks to packet-friendly infrastructures that support digital voice, video, Internet and other related services is now apparent in all networks. These networks multiplex a variety of communication services delivered to customers with high expectations, commanding flawless reliability, easy upgradability and scalability, as well as superior operational efficiency.
Fiber Characterization for 10G to 40G/100G Network Expansion
When it comes to high-speed transmission, especially 10G and 40G/100G, assessing fiber quality is a must. Once the basic parameters (i.e., loss, ORL, etc.) are under control, the next step is to qualify the fiber and ensure that it is fit to carry customer traffic. Polarization-mode dispersion (PMD) and chromatic dispersion (CD) optical testing become crucial at high speeds. The primary goal of any communication network is to maintain the quality and integrity of the optical signal transmission. New or upgraded networks must be characterized to ensure their different parts and components do not induce bit-error-rate (BER) levels that exceed communication system requirements.
