 A Quick Start Guide to Fiber-to-the-Antenna (FTTA) Installation and Maintenance Testing
FTTA
Staggering increases in bandwidth demand are forcing network operators to new models of mobile infrastructure
like FTTA to improve the user experience and reduce costs. Optimized cabling and component performance
between the radio remote unit (RRU) and the base band unit (BBU) is key to delivering optimized system
performance between the backhaul network and the end user.
Network professionals must ensure network uptime and reliability while maximizing the customer experience. The
comprehensive VIAVI suite of fiber optic handhelds, portables, and inspection test solutions for FTTA help support
this goal.
Fiber Optic Cell Acceptance Test (FOCAT) Tier 
Certification
Installing a fiber network requires close consideration of network
topology and equipment specifications. One of the essential tools to
provide Tier 2 certification is an optical time domain reflectometer
(OTDR). An OTDR measures the end-to-end optical link loss and
provides the optical loss and distance for all other impairments
(events) along the fiber.
An OTDR is the only single-ended tool able to measure loss from all
of the components along the fiber link such as connectors, splices,
microbends, and macrobends; these measurements are vital for
correctly characterizing the quality of installation or when fault
finding. The ability to do single-ended measurements can dramatically
impact operational costs when construction or troubleshooting a FTTA
network and, in some cases, can prevent unnecessary tower climbs.
FOCAT certification provides the confidence that network components
are optimized to provide a lifetime of performance and deliver world-
class services.

testing topics only. Visit www.viavi.com/go/GetFiberSmart for more
