IEC Grade A for all USource fiber patch cords

Time:2018-04-28 Views:233
USource fiber optical patch cords all comply with IEC Grade A
 IEC grade A/B/C
 ‘C’ Grade connectors have the following performance characteristics: attenuation: ≤0.25 dB mean, ≤0.50 dB max, for >97% of samples; return loss: ≥35 dB.
‘B’ Grade connectors have the following performance characteristics: attenuation: ≤0.12 dB mean, ≤0.25 dB max, for >97% of samples; return loss: ≥45 dB.
A’ Grade connector (that is yet to be officially ratified by IEC) has the following performance characteristics: average insertion loss of 0.07 dB (randomly mated IEC Standard 61300-3-34) and a maximum insertion loss of 0.15 dB max, for >97% of samples. While the return loss using IEC 61300-3-6 Random Mated Method is >55 dB (unmated - only angled connectors) and >60 dB (mated), this performance level is generally available for LC, A/SC, SC and E2000 interfaces.
