Yesterdays fast is todays slow
Yesterdays incredible is todays expected
Yesterdays connector budget is todays link budget
Link budgets are tight because:
• “Zoned” Data Centers require 4 or more connections in a channel
• Manufacturers offer “Ultra Low Loss” components
• Customer seek a “Future Ready” infrastructure

Testing - “Zoned” Data Centers
After the installation only the links can be tested
The “Patched Channel” is configured by the network user
Total budget 10G: 2.6dB 40/100G 1.5-1.9dB
There is very little room for error !

Pro & Con
Truly measure the loss Most accurate Not suited for trouble shooting
Most effective for trouble shooting Identifies bottlenecks Less accurate loss “calulcation”

Dry clean will only remove dust and fresh skin oil
Inspection will tell whether…
– Wet cleaning is needed
– Wet cleaning was successful
– Abrasive dust could damage the mated plug
– Replacement is needed

In the past …
…Expensive & Bulky
It is highly recommended by many manufacturers in particular when testing highest grade components for very demanding limits
Today …
… 1.) Less expensive 2.) Smaller then a mandrel
It helps to prevent1. FASLE FAILs
… Revenue at risk2. FALSE PASSes
… Reputation at risk
Never …
… does not work reliably

Similar to SC/LC/ST/FX/…
• Non critical connection on the power meter (critical for 1 jumper method)
• EF compliance
Unique to MPO….
• Test all 12 fibers
• Identify polarity: “A”, “B”, “C”& “special”
• 1 jumper method & pinned or un-pinned links… solved with PanMPO™
Special MPO testing needs ?

EXTENDED Test Regime
Why EXTENDED Testing ?
Identify, locate and eliminate unnecessary bottlenecks in otherwise compliant links
Further increase performance margin
Identify connectors with excessive reflectance
Document the state of the installation
Testing with a SMART Loop
> 9 out of 10 OTDR tests are performed incorrectly. The list of reasons is long– No Bi-Directional test and/or
averaging
– No tail fiber
– Incorrect handling of launch and tail fiber
– Adaption with hybrid cords
– etc.
A SMART Loop concepts forces the user to perform the test correctly
Multiple remote loops support operation by 1 technician

Inspection equipment
Without inspection equipment, you will never know if the connector is clean or not
Even with inspection equipment, thereare arguments as to what is acceptablefor a fiber connector
IEC 61300-3-35 defines levels ofacceptable scratches and debris on theend faces of fiber connectors
Automated field inspection is something to consider
Images can be stored and made part of the documentation
