N129 LANmark-OF Female MTP-LC Assemblies

MTP*-LC harnesses allow the rapid deployment of high density patching in SAN and LAN environments in data centres. The I/O density of active devices is increasing. Blade chassis currently reach 48 optical ports (96 LC connectors) per blade with blade densities reaching eight to 18 per chassis. This creates a challenging optical cabling and connectivity management situation.

Nexans’ Optical Harness Assembly enables superb cabling management using staggered links optimised to grow as your system grows while maintaining flexibility and control.

Construction
A round cable with a diameter of 3,65 mm is terminated on one side with a female MTP-connector. The other side is terminated as a staggered fan-out with uniboot duplex LC connectors. The round fan-out legs contain 2 fibres.

The stagger between the uniboot connectors is set to minimize excess cable: The distances between the uniboot connectors is standard set at 15 mm+/-5mm.

For a left staggered fan-out the first uniboot connector is located at 600 mm from the fan-out point and is labelled as port “1”. The sixth uniboot connector is 675 mm from the fan-out point and has label “6”.
For a right staggered fan-out the first uniboot connector is located at 675 mm from the fan-out point and is labelled as port “1”. The sixth uniboot connector is 600 mm from the fan-out point and has label “6”.
For a straight fan-out all connectors are located 600 mm from the fan-out point.
 

The uniboot connector with label “1” is always connected to the most left port of the Plug&Play-module.
 

The length between the MTP-connector and the fan-out point is variable and can be increased in steps of 1 m.

Custom configurations are available on requests. They are designed to suit for the user’s component lay-out.

Features and benefits

• Small bend raduis
• Bend insensitive optical fibres
• Available in OM3, OM4 and Singlemode mode (OS2)
• Cable jacket aqua for OM3/OM4 and yellow for Singlemode

Performance and polarity
The MTP connector is a low loss connector. Typical value for the insertion loss for the low loss MTP-MTP connection is 0.2 dB. The limit value is 0.35 dB measured according to standard IEC 61300-3-45.

The polarity is optimised for following channel: Plug&Play-module + MTP/LC Harness. The female MTP-connector of MTP-LC harness fits with the male MTP connector of the Plug&Play module.

Bending radius of the cable is 40 mm.

Cable is flame non propagation (IEC 60332-1) and fire non propagation (IEC 60332-3)
