FTTH fiber optical terminal box, outdoor fiber optic termination box is used in wiring connection between optical cable and optical communication equipment, through adapter in distribution box, optical fiber jumper leads optical signal, realize optical wiring function, and can meet the optical splitter placed to achieve spectral function.
The equipment is used as a termination point for the feeder cable to connect with drop cable in FTTX communication network system. The fiber splicing, splitting, distribution can be done in this box, and meanwhile it provides solid protection and management for the FTTx network building.
What Is Glass Sealing toThermisr
Glass thermistor is a glass-sealed thermistor. Common glass sealing thermistor are: single-ended glass thermistor, diode glass seal, SMD glass seal. Because of the glass insulation, the thermistor is not affected by the additional temperature, greatly improving the sensitivity and accuracy of the control.
Glass Sealed Thermistor Characteristics
High interchange accuracy
Excellent solderability and thermal shock resistance
Wide operating temperature range
Excellent moisture resistance
Low loss, small size
Automated mass production to ensure that the products of high quality and high stability
Composition Structure And Production Process
1> single-ended glass seal: thermistor chip and copper wire welding, use a bead-like glass case package. Single-ended glass-type products are the smallest thermistor.
lead package allows for manual or machine is mounted;
Packing: 1000 pcs / bag;
Note: When installing the product, two wire can not touch.
