1. Important Recommendations
1.1. General Information
A good setup for long term testing has additional challenges compared to standard IL/RL measurements.
The two most critical aspects are:• connector contamination• microcracks and fiber management
Before connecting any jumper to the instruments, inspect both ends with a microscope. A bench top ferrule
inspection scope such as JGR’s CS400K is recommended for inspecting jumpers and connectorized switch pigtails.

When connecting directly to an instrument bulkhead, a bulkhead inspection probe can facilitate the process.
Even dirt in the peripheral zones outside the core can affect long term IL stability. Extra diligence is required.

1. Important Recommendations
1.1. General Information
Fiber microcracks are difficult to detect and a slow IL drift over many hours or days is a common manifestation. If
possible, replace any fibers that are suspected of having microcracks.

Microcracks are especially sensitive if the fiber is bending. It is recommended to have enough flat space to allow
the fibers going from the instruments to the chamber to be as straight as possible. Avoid any crossed fibers.
Hanging fiber is another common source of drift. This is sometimes unavoidable between the bench and theenvironmental chamber but fiber should be supported as much as possible.

The lab conditions should be optimized for temperature and humidity control. For example, the Telcordia GR-326
standard defines ambient lab conditions for temperature = 23 ± 2 °C and RH < 75%.
The EOTS software can apply external fiber drift corrections from reference channels. It is recommended tomanage the fiber in such a way that the reference channel is within the bundle of channels it is correcting as
much as possible outside the chamber.

2. Software and Hardware Installation
2.1. Software Installation
If you have purchased a complete EOTS in a rack with server PC included, the software and hardware have been
pre-installed and you can skip section 2.

If you wish to use the EOTS software for an RL1 and SX1s purchased separately or need to set up a new computer,this section will cover the setup process.
Begin by running the JGR Environmental Test Suite.exe installer.
This will install the necessary VISA drivers to control the RL1 and SX1 and the following two applications:• JGR EOTS – main software to run test sequences• JGR Data Tools – software used to view data and export to Microsoft Excel
The EOTS software auto detects instruments on launch. If the application is running, close it before proceeding tothe hardware connections.

3.2. Setting Reference Channels
The reference channels compensate for external fiber IL drift. It is suggested to bundle the fibers together asmuch as possible and include each reference channel within its corresponding group.

The reference channels are the physical channels on the switches. All other EOTS channel numbering will beadjusted accordingly.
For example, a 100 channel EOTS comes with 2 reference channels:• each switch has 102 physical channels• REF #1 is assigned to physical ch 1
• REF #2 is assigned to physical ch 52• the displayed channels in the MEASURE, CONFIG and PLOTS are adjusted accordingly• EOTS ch 1 = physical ch 2
• EOTS ch 2 = physical ch 3
• ..
• EOTS ch 51 = physical ch 53• ..
• REF #1 compensates for EOTS ch 1-50
• REF #2 compensates for EOTS ch 51-100

The definition of the different lengths are shown in the following pages. They are the reference lengths for RLAand RLB.
In the case of a bidirectional RL1 (ex: RL1-2X-3050-S-09FA):o each switch must have defined launch and receive lengths
In the case of a single output RL1 (ex: RL1-01-3050-S-09FA):o the launch switch must have a defined launch lengtho the receive switch (or fanout) must have a defined receive length
Each switch must have a defined MTJ length.

3.5. Direction 1 Length References and System IL•••

It is recommended to use a 3m jumper with a flat polish (PC) connector for the length referencing.
Alternatively, an APC jumper can be used. Putting on a dust cap will increase the reflection and may help incases where there is some uncertainty.
Inspect and connect the UPC stub from launch ch 1 to the detector and measure the Output (Launch) IL.

Typical values are < 2 dB
