LANmark-OF METHOD B MPO/M-MPO/M Pre-Term SM OS2 G.657.A1 12c LSZH xxxM Yellow Pulling Eye one side

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

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 IEC 60332-3c. The cable meets LSZH requirements.

MPO-MPO Pre-Term characteristics

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

The Pre-Terms are optimized for both pulling and laying in data centers. On both sides the MPO connectors are protected by a bubble foam. The maximum pulling force on the pulling eye is 450N. Pre-term are ordered with 2 options available: Pulling eye on one side or No pulling eye. A detachable pulling eye with corrugrated tube can be ordered separately using PN N890.100HP.

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

Optical Performance and Polarity

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

The insertion loss for a singlemode the MPO connection has typical performance of 0.5dB with a maximum of 0.75dB insertion loss.

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

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

The method B Pre-Term has a key up / key up design. This is in agreement with standard TIA-568.3-D-2016 method B.
