2 ACCESS LINK MONITORING 2 Dark Fiber Services Become More Strategic The need for fiber-optic transmission is rapidly expanding to cope with the ever increasing bandwidth requirements driven by new applications such as video-related services and cloud applications. Fiber access infrastructure is necessary in competitive environments and also a key enabler for next-generation all-optical IP networks. Bringing the optical fiber as close to the user as possible is critical for network performance and user experience. This drives fiber deployment further out in existing access networks and at the same time opens up new business opportunities to connect public buildings and enterprises. Regardless of the type of organization and the size of the business, there is an increasing reliance on the network from basic Internet access to network applications to cloud service access. Because network-based applications are becoming more important and organizations have moved mission-critical applications to the cloud, they need higher capacity and want stricter service level agreements to ensure those applications perform as desired. Maximum Network Performance Mobile network operators, enterprises and government entities increasingly turn to dark fiber as an alternative to lit services. For organizations that need major bandwidth and maximum network performance, dark fiber services improve network performance capabilities and offer long term cost efficiency. Lighting the fiber with own equipment allows optimizing and customizing network performance. For low-latency applications, dark fiber provides organizations including high-frequency trading companies and mobile network operators the ability to squeeze out additional microseconds by selecting their own highly specialized transmission equipment or eliminating equipment altogether from connections short enough to cross-connect the dark fiber directly into terminating equipment. Dark fiber services also guarantee minimum delay variation, a performance characteristic critical for mobile fronthaul and backhaul connectivity as well as applications relying on precise time-of-day distribution. Complete Control and Virtually Unlimited Scalability Dark fiber services provide physical security and complete control to shape every aspect of the network. They are great for organizations that are growing quickly and need to manage scalability for point-to-point connections. Whenever they need to upgrade bandwidth, they can change out or add equipment interfaces on their own without coordinating with a service provider or worrying about long-term contractual obligations on a leased circuit. Dark fiber services are also beneficial for organizations that need to manage the technology evolution on their high bandwidth data connections. This can be the case for connections between data centers that require a variety of interfaces that may not be standard or available from network operators servicing those locations. Dark fiber services also provide direct access to the full suite of performance management statistics offered by the client equipment. The Dark Fiber Monitoring Challenge Leasing dark fiber and passive optical extension services is not like buying most other telecom services because it is more like a physical asset than a service. Outages are typically much longer than for other services and commonly established Service Level Agreements (SLAs) for dark fiber service are no longer adequate for many applications and businesses. Increased availability and pro-active service restoration are desired performance characteristics, expressed by many operations. The main reason for offering dark fiber and passive optical access services with basic performance guarantees is driven by the cost-sensitivity in access networks. Traditional technology can provide pro-active, in-service monitoring, however at cost points that do not support the business case. Deploying active equipment for high-capacity service termination at the service end point is therefore often avoided, using dark fiber to extend the service over the last mile instead. Another challenge is service transparency for transporting special protocols that do not support standardized performance monitoring tools or performance requirements that do not allow mapping the native data signal into common transport protocols such as Ethernet, MPLS or OTN. Switching to passive wavelength and dark fiber services has become the rule in this case. Challenges with Traditional Dark Fiber Offerings Dark fiber is more like a physical asset than an assured telecom service Fiber network operators have no visibility on performance and availability Reactive troubleshooting and service restoration triggered by customer Soft service level agreements that are no longer adequate for evolving applications Outages are typically much longer than for other telecom services

3 ACCESS LINK MONITORING 3 Dark Fiber Access for Diverse Applications There are several ways to provide network access including lit services, dark fiber and passive wavelength services. Dark fiber and passive wavelength services excel at providing high-performance connectivity with little added overhead. This makes them ideal for applications where primary considerations include extremely low latency with very high throughput, where no network protocol is desired and where distances are relatively short. There are also situations in which dark fiber is the only solution, particularly when specialized network protocols are utilized. Dark fiber installations exist in most urban and metropolitan areas and services may be leased from the companies that installed it or from operator companies that manage and market dark fiber. There are numerous applications that are driving the growth in dark fiber and passive wavelength services today. Organizations including mobile network operators, enterprises and government entities favor the utilization of un-lit services to control scalability, manage latency extremely tightly, control network management and manage technology evolution. Radio Access Network Connectivity With many of the large-scale mobile backhaul networks installed to accommodate the growing 4G LTE service base, there has been a call by a number of mobile network operators for dark fiber solutions. Backhaul services based on dark fiber allow mobile network operators to maintain complete control over backhaul network performance and offer long-term cost efficiency. Linking cell sites with dark fiber directly permits new consideration of options revealing significant potential for reduced latency, increased capacity and lower total cost of operation. Mobile network operators also have turned to acquiring dark fiber and passive wavelength services from their landline service provider partners because of the emergence of mobile fronthaul in Centralized Radio Access Network (CRAN) architectures for macro and small cells. The Common Public Radio Interface (CPRI) protocol utilized by CRAN has service performance requirements that do not allow mapping the native data signal into common transport protocols such as Ethernet, MPLS or OTN. For both mobile backhaul and fronthaul applications, a strict SLA for leased, un-lit services is critical to maintaining superior mobile user experience and stable radio access network operations. Business Applications for Enterprise and Government Enterprises and large corporations are increasingly leveraging dark fiber networks to interconnect their data centers and other mission critical facilities for cost-effective transport, high availability for applications and business continuity plans. The emergence of mega data centers operated by major Internet Content Providers (ICPs) and the increased adoption of cloudbased services by enterprises and residential users have fueled this trend. In addition to that, dark fiber and passive wavelength services are an excellent option for academic institutions and government entities looking to make a long-term investment in network infrastructure and to have complete control over network design and layered architecture. There is a general market trend where high-end enterprise organizations and governmental institutions including the research and education sector want greater security and control over their network. And dark fiber provides all of that. Compromising improvements in security and control by reduced network availability is however not an option, calling for pro-active monitoring and troubleshooting of dark fiber services for increased SLAs. Passive Optical Extension Services With the increasing capacity of long-distance private line services helping large and distributed organizations to maintain a competitive edge with quick access to time-critical information and communicating using streaming video, cost-effective service extensions from the long-distance network point of presence become more challenging. Deploying active equipment for high-capacity service termination at the service end point is often avoided for cost reasons, using dark fiber to extend the service over the last mile instead. Providing these passive optical extension services without pro-active service monitoring capabilities has a significant negative impact on the over-all service availability of the end-to-end service offering.

The new FSP 3000 ALM is specifically designed for high scalability and maximum cost-efficiency, two criteria critical to efficient access network operations. Interference with services and applications provisioned on top of the passive infrastructure is prevented by spectral separation, maintaining full transparency and providing complete control to shape every aspect of the network to the client organization s need. Increasing Service Performance Being immediately notified of a fault in the fiber access infrastructure and understanding which customers are impacted allows fiber network operators to move from reactive troubleshooting to pro-active management of dark fiber and passive wavelength services. Notification of affected customers and service restoration can be triggered immediately. When deploying FSP 3000 ALM, operators now have full visibility on their physical fiber infrastructure in real-time and can offer strict SLA commitments while managing them easily and ensuring that no penalties are incurred. The FSP 3000 ALM incorporating Optojack technology is designed for 24x7 monitoring and scales in a cost-effective manner with the number of dark fiber services provisioned. If failures are detected, network maintenance teams will be immediately alerted and are able to quickly identify the cause of the problem as either being fiber-related or the result of network equipment failure on the client side. If fiber-related, the maintenance organization will know the exact location and the reason for the fault. In both cases, this information will be in their hands within minutes, enabling them to assign the correct crew or contractor to perform the repair. Making Network Operations More Efficient Pro-active service monitoring and simplified network management play a critical role in operational efficiency and optimizing the time and resources available for network maintenance. When the coverage of the access fiber infrastructure grows and SLA commitments become more demanding, the capability to understand issues in detail, isolate problems and localize faults within minutes is critical to success. The FSP 3000 ALM supports access fiber network operators with their challenging task of efficiently operating their fiber network infrastructure. Designed with multi-tasking capability for access fiber monitoring, it allows automatic execution of multiple concurrent measurement cycles on different fiber routes on a continuous 24x7 basis. Service degradations and outages resulting from poor fiber installation, bends, fiber and cable cuts, disconnect and reconnect events as well as issues on the client side of the installation can be detected and classified reliably. Immediately reporting the cause of the problem and its exact location enables network maintenance teams to repair faults quickly, involving minimum resources. Growing Topline and Profitability Increased service performance and most efficient network operations are the cornerstones of a successful business in telecommunications. With the FSP 3000 ALM, operators of fiber network infrastructure can now offer a completely new class of dark fiber, passive wavelength and fiber extension services. The added value of pro-active monitoring and fast fault resolution significantly increases the attractiveness of their services and allows them to monetize their fiber infrastructure at increased profitability. Having the possibility to monitor access fiber infrastructure at lowest cost and while in service also enables fiber network operators to be in a stronger position in their negotiations with partners and contractors for civil construction and fiber deployment. Acceptance of new fiber cable installation can now be extended beyond verification of birth test data, effectively enforcing a 12 or 24-month new cable installation warranty.
