¹Maximum insertion loss for 2,5 mm ferrules is based on interoperability and 2 standard deviations. For maximum insertion loss, 95% should meet the specification. During testing of the insertion loss using a master test cord (MTC), the maximum allowed test is to be less than 0,07 dB to achieve interoperability

²Maximum insertion loss for 2,5 mm ferrules is based on interoperability and 2 standard deviations. For maximum insertion loss, 95% should meet the specification. During testing of the insertion loss using a master test cord, the maximum allowed test should be less than 0,17 dB to achieve interoperability

³Except for E2000 which is 0,40 dB maximum.
