Outline of GR-1221 Test Standards
The Thermal Shock Test is performed in a temperature chamber to verify that the optical splitters are not structurally compromised when transported from a one temperature extreme to another.
While FBT splitters may have a narrower temperature operating range compared to PLC splitters, they can still perform well within their specified range. However, extreme cold temperatures near -20 Celsius might pose chal...

The Thermal Shock Test is performed in a temperature chamber to verify that the optical splitters are not structurally compromised when transported from a one temperature extreme to another.
The splitter shall pass the cyclic moisture resistance (temperature-humidity cycling) test and be based on the procedures stated in MIL-STD-883, Method 1004, with reduced ramping time to the subzero
While FBT splitters may have a narrower temperature operating range compared to PLC splitters, they can still perform well within their specified range. However, extreme cold temperatures near -20
Designed for cold climates (e.g., Alaska, Siberia), this fiber uses a low-shrink acrylate coating with a higher glass transition temperature (Tg), reducing microbending at low temperatures.
This order further provides guidance towards the design of the fiber optics cable loop at airports as well as the selection of the specialized components of the fiber optics system.
The use of MICROSENS Micro Switches permits an extension of the fiber optic backbone all the way to the tertiary level of containment (cable ducts, sub-floor boxes as well as in-wall, on-wall and desktop
This standard establishes the minimum requirement when using fiber optic transmission systems (FOTS) and equipment to support air traffic control facilities in an airport or terminal environment.
PLC splitters should have good temperature stability, with wavelength-dependent loss and temperature stability of 0.3dB in the temperature range of -40 to 85°C.
In the case of fiber optic connectors, adapters, splitters and other passive fibre optic elements designed to operate in temperatures from -40°C to +85°C, additional protection against
Testing a splitter or other passive fiber optic devices like switches is little different from testing a patchcord or cable plant using the two industry standard tests, OFSTP-14 for double-ended loss
