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 !

Truly measure the loss Most accurate Not suited for trouble shooting

Most effective for trouble shooting Identifies bottlenecks Less accurate loss “calulcation”

Inspect & Clean

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

Dirt will transfer

Conclusion: Clean measurement cord after every mating

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

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
