1.2 mm BootSC Premium 1.2 mm Connector

SENKO’s SC Premium Connector 1.2 mm boot is based on the Senko Premium SC range and specifically designed to accept
a reduced size, 1.2 mm cable that is commonly found in highly dense telecommunications cable racks and cabinets.
Cable assemblies utilizing the SC Premium connector with a 1.2 mm boot offer a substantial reduction in equipment
congestion, while maintaining the performance, quality, and reliability that are typically associated with larger cables.
The SC Premium connector with a 1.2mm Boot has been designed to meet the requirements of GR-326 15lb Proofand TWAL test for media 1 to reduce cable congestion without sacrificing mechanical strength.*
As with all the SC Premium connector range, this version has been specifically designed and optimized to meet themost demanding of applications to give class leading low loss performance. It uses high quality components andkeying features to achieve the best possible fiber to core-to-core alignment, dramatically minimizing the effect ofApex Offset and achieving superior Insertion Loss and Return Loss results.
As with all SENKO SC Connector ranges, the SC Premium connector 1.2 mm boot it is fully compliant to IEC 61754-4 with apush pull mechanism and 2.5 mm ferrules and can be configured for singlemode and multimode fiber.

FEATURES• Compact design for 1.2 mm cable without a reduction inrobustness compared to 2.0 mm and 3.0 mm cable• Senko premium connector with superior Insertion andreturn loss
• Fully compliant with IEC 61754-4• Push-pull coupling mechanism for repeatable andsimple installation• Singlemode and multimode variants• Housing can be color-coded• Typical IL SM 0.08dB (UPC), MM 0.10dB*Note: Cable and termination dependant

APPLICATIONS• Telecommunications networks• Data center networks• FTTX networks• Premise distribution networks• Industrial and defense systems

KEY BENEFITS
