Patch cord certification

CHANNEL ADA PTERS
•
The channel measurement excludes the connection to the adapters
•
For patch cords, we want to measure that RJ45 connection
•
This is not a valid test
•
You are only measuring the cable
•
Patch cord testing is found in - ANSI/TIA-568-C.2 - ISO/IEC 11801:2010 and IEC 61935-2 © 2014 Fluke Corporation. All rights reserved.
PATCH CORD ADAPTERS
•
The patch cord measurement includes the connection to the adapters
•
Using patch cord adapters, DSX includes that RJ45 connection
•
A special laboratory tested RJ45 Jack is used - Called out in standards for patch cord certification
•
The patch cord limits are tighter than the Channel limits as well
© 2014 Fluke Corporation. All rights reserved.
CHANNEL VS PATCH CORD TESTING
•
Same patch cord, different adapters/limits
Margin looks too good? You are only measuring the cable, nothing else, so yes! © 2014 Fluke Corporation. All rights reserved.
THREE PATCH CORD ADAPTERS
•
DSX-PC5e - For testing to ISO/IEC 11801 and ANSI/TIA-568-C.2 Category 5e
•
DSX-PC6 - For testing to ISO/IEC 11801 and ANSI/TIA-568-C.2 Category 6
•
DSX-PC6A - For testing to ISO/IEC 11801 Category 6 A and ANSI/TIA-568-C.2 Category 6A*
•
The DSX-PC6A is not backward compatible with Cat 6 or 5e
* ANSI/TIA currently specifies a jack with a different performance to ISO/IEC. However, ANSI/TIA is in the process of allowing the jack specified in ISO/IEC for patch cord certification, so the DSX contains the proposed limits for Cat 6A testing
© 2014 Fluke Corporation. All rights reserved.
WHY TWO ADA PTERS?
•
Why can’t we use the patch cord adapter for channel testing too?
•
FEXT cannot be excluded using DSP techniques
•
Need an adapter with excellent FEXT
•
The patch cord adapter does not have excellent FEXT - It must meet specific FEXT requirements of ANSI/TIA and IEC
•
The channel adapter has excellent FEXT - But as a result, it has poor NEXT - That’s ok, because it can be gated out using DSP techniques
Excellent FEXT
FEXT limited by standards requirement © 2014 Fluke Corporation. All rights reserved.

WHAT IS AL IEN CROSSTALK?
•
Alien crosstalk is the coupling of noise from one link to the other
•
When a cable is surrounded by other cables, noise from those cables will impact its ability to transmit data – we call that Alien Crosstalk
•
The cable we wish to measure for Alien Crosstalk is called the Disturbed (Victim) and the adjacent cables are called the Disturbers Disturbers

Fiber testing Tier 1 and Tier 2
© 2014 Fluke Corporation. All rights reserved.
TIER 1 AND TIER 2
•
Tier 1 - Often referred to as OLTS or Optical Loss Test Set - Uses a source and power meter - Reports the difference between power in and power out in dB - Duplex (two fiber) testers can also measure length
•
Tier 2 - Often referred to as OTDR or Optical Time Domain Reflectometer testing - Injects a series of light pulses into a fiber and measures the backscatter returned to the OTDR port - Single ended test but must be done in both directions - Implies loss based on change in backscatter between events - Depends on good reflectance which field polishing often fails to achieve

MULTIMODE FIBERS
•
Mode: from the Latin “path”; so it means multi-paths
62.5 µm
•
125 µm
The modes arrive at different times causing the signal to spread
© 2014 Fluke Corporation. All rights reserved.
APPLICATIONS LIMITED BY DISPERSION/LOSS
•
Modal Bandwidth (MBW) -
•
is the unit to classify dispersion in the cable
50 /125 µm has less dispersion -
– it’s core is smaller than 62.5/125 µm fiber
•
Your loss may be lower than the allowed fixed loss, but if it exceeds the length found here (IEEE 802.3) there may be errors on the network
•
IEEE 802.3ae specifies 400 m, cabling vendors may specify 550 m © 2014 Fluke Corporation. All rights reserved.
SINGLEMODE FIBERS
•
Mode: from the Latin “path”; so it means single-path
9 µm
•
125 µm
There is only one mode, so no signal spreading this time

MIXING MULTIMODE FIBERS
•
What happens when you connect a 62.5/125 µm to a 50/125 µm?
50 µm
125 µm
•
Many of the modes will disappear into the cladding – forever!
•
There will be a significant loss (as large as 4 dB)
•
Also known as a coupling loss
•
This happens a great deal as users migrate from 62.5 to 50 µm fiber

CLEANING
•
Fiber testing is all about cleaning and inspecting
•
Without the appropriate cleaning supplies AND inspection equipment, you CANNOT test fiber
•
Dust in an office is typically between 2.5 µm and 10 µm
•
All fibers should be inspected and cleaned before being used, even if they are brand new out of the bag
© 2014 Fluke Corporation. All rights reserved.
CLEA NING KIT
•
Isopropyl Alcohol (IPA) is typically used - It should be better than 98% (rubbing alcohol is 70%) - Local pharmacy stocks no better than 91% (not good enough)
•
There are disadvantages to IPA - Over time, absorbs water and is no longer 98% - Will not remove non ionic compounds - Tends to leave a residue behind if you are not careful
•
Hybrid cleaners are better, such as the Fluke Networks Fiber Optic Pen
•
There are significant advantages with these new hybrid cleaners - Aggressive cleaner, better than IPA - Evaporates very quickly, less likely to leave residue behind - Has antistatic properties so dust in the air is less likely to be attracted to the end face of the connector © 2014 Fluke Corporation. All rights reserved.
CLEA NING KITS
Click pens ideal for ports, not for cleaning patch cords where end faces are subject to grease from fingers Wet to dry cleaning is ALWAYS better
© 2014 Fluke Corporation. All rights reserved.
CLEA NING WITH CLICK CLEA NERS
•

•
Cleans Ports on devices and patch panels as well as Cords ….with an adapter
•
Dry cleaning is less efficient for cleaning grease (dried skin oil) than wet cleaning with a solvent and swabs/cleaning cubes
© 2014 Fluke Corporation. All rights reserved.
OPTIMAL CLEANING METHOD
• • •
Peel cover from unused “N.” Apply a minimal amount of solvent from the Solvent Pen Place end-face perpendicular to card in first corner of unused “N”
•
Swipe through “N” shape using gentle pressure and moving from wet to dry Check end-face with microscope, place cap on test reference cord

Tier 2 Fiber Testing (OTDR)
© 2014 Fluke Corporation. All rights reserved.
WHAT IS AN OTDR?
•
Optical – measurements carried out using pulses of light.
•
Time Domain – signal is plotted against time delay.
•
Reflectometer - signal we’re looking at is caused by reflections (and scattering) in the fiber.
•
The OTDR launches a very short pulse of light into a fiber and then looks at the very low levels of light which come back out of the same end of the fiber.
•
This returned light comes from reflections where there is a change of refractive index in the light path (called Fresnel reflections) and from a scattering effect which takes place within the fiber called Rayleigh Scattering. © 2014 Fluke Corporation. All rights reserved.
WHAT IS AN OTDR?
•
The OTDR produces a trace of the returning light level against the time delay compared to when the pulse of light was launched.
© 2014 Fluke Corporation. All rights reserved.
WHAT IS AN OTDR?
•
With suitable processing and interpretation, this trace can then be used to provide information about every portion of the fiber being measured
•
EventMap™ interprets the trace for you
© 2014 Fluke Corporation. All rights reserved.
CAN BE USED TO TEST A REEL OF FIB ER
•
Although the fiber is tested in the factory, it can be damaged during delivery or storage on site
•
It is standard practice to use an OTDR to ensure no breaks in the cable – but requires “expertise” to review the traces Mechanical splice*
*Could be a mechanical connector
