Inspect before you connect – the fiber face must be inspected before connecting, to ensure a clean, reliable
connection. Dirty connections can cause problems that may be difficult to troubleshoot later. The P5000i
simplifies this process with clear pass/fail results. The P5000i connects to VIAVI instruments or a smartphone/
tablet via the USB port. The tech simply cleans the fiber face, and when the inspection passes and continues with
assurance that the connection will be reliable.
Optical power – checking optical power level is also a quick and easy way to improve first time install success
rate. The MP-60 is a broadband power meter which connects via USB, and is suitable for use in single wavelength
environments where only a single PON service is being delivered (e.g. a single 1490nm downstream wavelength
for G/E-PON) the tech can verify optical power level at the ONT and troubleshoot as needed. Situations where
more than one downstream wavelength is present on a fiber (e.g. G/E-PON plus 1550nm RF overlay) will require a
dual band or wavelength selective power meter such as the SmartPocket V2 OLP-37XV2 or the Optimeter.
Drop Certification and Connection Quality Verification – For PON/FTTH, to ensure successful installation and
activation of service on the first visit and to reduce the amount of unnecessary fault escalations, CPE swap outs
or drop fiber replacements fiber end face inspection and power level checks must be combined with certification
of the fiber drop and verification of the quality of connection to the PON (splitter). The Optimeter provides
everything a tech needs in one simple and fast solution. In just 1 minute, with a single fiber connection, and 1 key
press, any tech can completely validate and certify a drop fiber. Presenting result on a single view means no need
to navigate between different screens and menus. While the fault-finding test feature gives a simple but powerful
troubleshooting tool enabling diagnosis of any fiber issue immediately while still on-site in order to determine
correct ownership of the repair.
Fiber, Ethernet, and WiFi – The Network and Service Companion (NSC-100) can be used to verify optical power
level, utilize PON ID information to confirm connection to the correct OLT port, prove the PON network’s service
delivery by testing throughput directly from the drop fiber and then validate service delivery within the premises
via Ethernet or WiFi (or both) networks in order to troubleshoot and optimize service coverage or set expectations
about service performance within the premises.
Test Process Automation
Problem: Even with the best test equipment, there are challenges for managing installation and service tests and
ensuring that the prescribed processes are being consistently followed. Some difficulties in process management
include the need with some test equipment to manually configure each instrument to conform to the process.
If the process isn’t automated, the testing is likely to be inconsistent, tests can be complicated, or the test
equipment may be out of date or not properly equipped with the test capabilities required. These issues can
be compounded with an inexperienced work force, and the need to communicate and coordinate the resources,
resulting in time consuming errors. Without automation, the results data is often inconsistent, with missing or
invalid data, and there is a lack of key performance indicators that provide insight into network performance.
This difficulty in deployment of consistent procedures (MoPs) leads to a longer work/rework cycle, delayed
deployment, unpredictable operational cost, unpredictable staff needs and activation schedules, inability to audit
results, and difficulty in addressing problem causes.
