Why should you use PD IEC/TR 62627-03-03 - Fibre optic interconnecting devices and passive components?
Since 2000, the optical power in transmission systems has increased in conjunction with the increase in the number of channels for DWDM systems, with the help of the deployment of RAMAN amplifiers and the application of optical amplifiers. It is pointed out, however, that the transmission media of the optical transmission system such as the optical fibre, optical connector and optical passive components may sometimes be hazardous because of possible leakage of high-power light that results in personal injury, melting, or damage possibly causing a fire.
PD IEC/TR 62627-03-03 states that the mechanism of return loss decline consists of the softening of an adhesive fixing the metal-doped optical fibre and ferrule, which in turn causes withdrawal of optical fibre and finally results in loss of physical contact (PC) between the fibre end faces. Therefore, for the purpose of guaranteeing long-term reliability with high power, it is necessary to control the internal maximum temperature within the range in which the adhesive does not exceed the glass transition temperature. Thermal simulation results lead to the assumption that the input power of 500 mW is the limit at the ambient temperature of 50 °C for SC plug style optical metal-doped fibre optical attenuator of 10 dB attenuation. Using PD IEC/TR 62627-03-03 you can describe the investigation results of high-power reliability for metal-doped optical fibre plug-style attenuators.
