MIL-STD-2042-6B(SH)
NOTE: For single mode fiber FOCT end-to-end attenuation measurements, MQJ1 may include a single loop with a diameter of 30 mm (1 in) to eliminate higher order mode power.

NOTE 1: Use the ST to ST MQJ with a hybrid adapter (for example, an ST to SC hybrid adapter) to connect to optical fiber cable ends terminated with connectors other than the ST and the MIL-C-28876.
NOTE 2: For COTS connectors that cannot be mated to an ST to ST MQJ using a hybrid adapter, non-standard MQJs may be used.
