Optical Time-Domain Reflectometer

Greenlee 930XC OTDR is an easy to use, full-featured handheld test instrument used by organizations to certify the performance of new fiber optics links and detect problems with existing fiber links. The 930XC OTDR is capable of measuring the length to a fault or the length of single mode and multimode fiber optic cables 

The 930XC OTDR also measures the reflectance and insertion loss of reflective and non-reflective events. 930XC is easy to learn so that even inexperienced technicians can measure, qualify, and troubleshoot today’s and tomorrow’s high bandwidth fiber networks. Professional test reports are easily generated using industry standard SOR files that can be saved as a PDF for full documentation.

Short learning curve allows the technician to be productive quickly Locates faults quickly so that fiber installations can restored with low down time

Applications: Validate installed fiber networks for compliance to design requirements Monitor and troubleshoot faults in fiber links

Why is datalogging important in buried pipe & cable locators.
While the cable pipe detector such as the CSCOPE DXL2 cable avoidance tool are thoroughbred professional tools for detecting cables & pipes which are built to perform,  if there is a cable cut, the subject will come down to  : 1. Was the cable avoidance tool used at all before the digging was initiated. 2. The second question would be - If yes, which modes was it utilized in ; i.e was only the power mode utilized for detecting energized power cables, or was the all scan mode used to detect all utilities in one sweep. 3. Third question, were the right gain settings utilized. While the use of the product is child's play for an experienced operator, it is the first chapter of a boo for a new or inexperienced or untrained operator. Data logging allows the supervisor or the manager to know  : Whether the equipment was utilized at all. ...
When is a ground penetrating radar beneficial in locating of underground pipes & cable utilities ?
The task of Locating underground utilities can be bifurcated into two deliverable: 1.Detection of underground utilities 2.Mapping of underground utilities If we take“a”this can be further subdivided into: 1. Detection of metallic cables & pipes, whether energized current carrying utilities or non energized utilities such as signaling cables, metallic pipes etc. 2. Detection of DI pipes, metallic manholes etc. 3. Non metallic HDPE telecom pipes, fiberglass manholes, etc. Underground cable & pipe utility locating requires the use a combination of various equipment’s and techniques which need to be chosen based on desired deliverables and then correctly employed to obtain the desired results. If the answer is “i”, an operator with basic training on usage of the ever dependable CSCOPE DXL2 Cable avoidance tool or CAT33XD Cable avoidance tool, can do the job blindfolded. If the answer is “ii”, an additional metal detector &/or magnetic locator is required. If the answer is “iii”. The use of a ...
How To Choose A Material Thickness Gauge - Part I
Thickness gauges are utilized where a micrometer or vernier caliper cannot be utilized – for measuring thickness of large sheets of metal or other substrates which can otherwise not be measured using the above devices. [caption id="attachment_54" align="alignleft" width="150"] Ultrasonic Material Thickness Gauge[/caption] A thickness gauge works on the principle of ultrasonics, i.e a signal is sent into the substrate through the transmitter  of an ultrasonic transducer which when received allows the thickness of the substrate to be measured. While all this sounds so simple, should all ultrasonic thickness gauges not be the same?  Which leads to the questions – 1.  what is the type of substrate under test ? egg, steel, aluminum, iron, titanium, glass etc. 2.  What are the conditions in which the thickness gauge will be used, will there be dust, oil, water ? 3.  Is it a simple sheet of material or a final product ? 4. How thin or ...
Stop Before You Dig
The civic layout of India based on the growing need for housing and roads has changed beyond recognition.  As a result As-built maps of underground utility assets, if existing , have been rendered redundant and cannot be used for reference for presence of buried utility assets. Jcb Excavators or manual labour at work in the country are digging in the blind at most times, at the peril of significant safety concerns of digging directly into live high voltage cables. Such cuts of buried cables can lead to , in order of priority , fatality to the person excavating and serious losses to the company who has taken the work contract. Not to mention the relative inconvenience to the citizens. The underground space is a jungle of energised power cables, dead power cables, water pipes, jelly filled telephone cables and optical fiber cables. The detection of these assets is ...
