LANmark-OF METHOD B MPO/M-MPO/M Pre-Term SM OS2 G.657.A1 24c Ultra Low loss OFNP xxxM Yellow

Pre-Term for data centres, buildings and campus based on Micro-Bundle.

The cable has a small diameter and bend raduis to meet data centre requirements.

Fire performance

The cables have been tested for fire performance according to Planum rated, providing a very high fire performance with minimal fire load and can be used in air flow space.

MPO-MPO Pre-Term characteristics

The MPO-MPO Pre-Term has standard pinned (male) connectors. This matches with the un-pinned (female) connectors in the female Plug&Play modules.

In order to reduce overlengths in data centers the Pre-Terms are custom made and available with 1m increments. The "xxx" in the N-number is the length in metre between the cable glands, i.e. the Pre-Term length between the back side of the patch panels.

After the cable gland the Pre-Term has a fan-out. The fan-out splits the cable into tubes. The tubes are reinforced with aramid yarns. At the end of each tube a MPO-connectors is mounted. The jacket of the tube is the same colour as the cable jacket. Close to the MPO-connector a label is installed to identify the number of the leg.

The MPO-MPO Pre-Terms come with a PG-13 cable gland that fits into the LANmark-OF ENSPACE and Plug&Play patch panel slots.

Optical Performance and Polarity

The insertion loss for a multimode the MPO-MPO connection has Ultra Low Loss performance: typical insertion loss is 0,2 dB with a maximum of 0,35 dB insertion loss.

The typical insertion loss for a singlemode the MPO-MPO connection  is 0,5 dB with a maximum of 0,75 dB insertion loss.

The insertion loss of a MPO-MPO connection is measured according to standard IEC61300-3-45.

The minimum return loss for a multimode MPO connection is 20 dB . The minimum return loss for a singlemode MPO connection is 45 dB. The measurement is according to IEC 61300-3-6.
