MPO-MPO Pre-Term characteristics
The round cable design facilitates the installation of the MPO-MPO Pre-Term: the small bending radius of only 30 mm in any direction eliminates the problems of preferential bending associated with traditional ribbon MPO cables.
Polarity in the optical channel during installation is guaranteed due to a pair flip fibre construction. This is in agreement with standard TIA 568-B-1-7-2006 method C. It allows the continuous use of the standard patch cords eliminating the need to buy optically straight patch cords. Also polarity is maintained with the same type of cassette on both sides of the channel without the need to flip the cassette on one side.
The Pre-Term is available with OM3, OM4 and singlemode fibres. The singlemode fibres are according to the specifications for G652D and OS2 cables. Details on the fibre specifications can be found in the detailed fibre datasheets.
The typical value for the insertion loss for a normal loss MPO-MPO connection is 0,3 dB. The limit value is 0,6 dB measured according to standard IEC61300-3-45.
The typical value for the insertion loss for a low loss MPO-MPO connection is 0,2 dB. The limit value is 0,35 dB measured according to standard IEC61300-3-45.
Mechanical characteristics of the Pre-Term are conform to the IEC-60794-20 standard for indoor cables.
The small diameter of 2.5 mm of the cable reduces significantly the expensive space required for cabling in a data centre and facilitates the airflow.
The MPO-MPO Pre-Term has standard non-pinned (female) connectors. This matches with the pinned (male) connectors in the MPO modules.
Consistent quality
In order to produce high quality, reliable pre-terminated multi-fibre cables, there are a number of physical characteristics that must be addressed. Therefore, all LANmark-OF MPO-MPO Pre-Term are fully terminated and tested in a quality assured factory environment. They are delivered with these test results.
