TCC-1000/2000 SERIES
Optical Cable Teperature Cycling Test Chamber
UNIVER TCC-1000, TCC-2000 Series Temperature Cycling Chamber is specially designed to apply temperature cycling on optical fibre cables in order to determine the stability behavior of the attenuation of cables submitted to temperature changes. It features large test chamber, precise temperature control as well as low temperature fluctuations
Changes in the attenuation of optical fibre cables which may occur with changing temperatures are generally the result of buckling or tensioning of the fibres resulting from differences between their thermal expansion coefficient and the coefficients of the cable strength and jacketing members. Test conditions for temperature-dependent measurements shall simulate the worst conditions.
This test can be used either for monitoring cable behavior in the temperature range which may occur during storage, transportation and usage or to check, in a selected temperature range (usually wider than that required for the above-mentioned case), the stability behavior of the attenuation connected to a substantially microbend-free situation of the fibre within the cable structure.
Adding cable suspending bracket and non-hygroscopic containers into chamber can realize Compound flow (Drip) Test according to IEC 60794-1-21-E14 / FOTP-81/ASTM D4565, an additional analytical balance is used to check the quantity of dripped filling or flooding compound for each cable specimen.

Features
- Large glass window design, viewing angle in all directions, hollow electric plating film and anti-condensation design, built-in lights to facilitate the test sample state of real-time observation in the course of testing.
- Heat preservation material used glass fiber cotton of high-intensity PU foam and high density, which can avoid unnecessary energy loss.
- Large-size LCD display screen, simple operation, easy to edit programs. PID with automatic calculation function, show failure message.
- Material quality of inner box is SUS304 # mirror-face stainless steel imported, and outer box is steel plate and the paint. Box body is processed shape using CNC machine tool, its shape is beautiful and fine.
- An RS-232 communication interface, matching recorder, strong expandability.
- With timing contact, and be able to cope with dynamic testing and measure test.
- The system-wide multi-security protection and power-cut memory.
- German compressor and environmental-friendly refrigerant (R134a, R404a, R23).
- Frozen system uses units or low-temperature dual-loop system design.
- Use more powerful wing-blower air supply cycle, to avoid any dead end, temperature and humidity are evenly distributed in the test region.
- Wind-road cycle adopted the design of blowing side wind and return wind. Wind pressure and wind speed are in accord with test standards, and make the door instantaneous temperature and humidity open that is stabilized time soon.
- Heating, cooling, humidification and dehumidification system is totally unaided to improve efficiency, reduce testing cost, increase life expectancy and lower failure rate.
- Adding cable suspending bracket and non-hygroscopic containers into chamber can realize Compound flow (Drip) Test according to IEC 60794-1-21-E14 / FOTP-81/ASTM D4565, an additional analytical balance is used to check the quantity of dripped filling or flooding compound for each cable specimen.
