The TERA Category 8.2 system supports autonegotiation and is backwards compatible to support copper-based Ethernet applications from 1 to 40 Gig in a variety of configurations. The system provides enhanced internal and alien crosstalk and insertion loss performance over Category 8/8.1 RJ45-based systems.

Category 7A

Siemon’s fully shielded end-to-end TERA Cat 7A cabling solution delivers 10 Gb/s performance and beyond, offers a bandwidth of 1.2 GHz per pair, supports cable sharing and is validated for TEMPEST high-security government applications.

Category 6A

Best-in-class performance, unparalleled usability and the industry’s fastest termination. Siemon’s Z-MAX® Category 6A is available in UTP and shielded Systems and features the highest performance margins across all critical transmission parameters.

Category 6

Siemon offers the UltraMAX™, MAX® Category 6 and Z-MAX® Category 6 cables for multiple levels of performance to either meet or exceed ISO/IEC and TIA connecting hardware and channel performance specifications for use in 10/100/1000BASE-T applications.

Fiber optic cabling and connectivity

Base-8 Plug and Play Fiber

Providing seamless transition from duplex 10 Gb/s to current and future 8-fiber applications. Current 40 and 100 gigabit (Gb/s) multimode fiber applications, as well as future 200 and 400 Gb/s multimode and singlemode applications, are based on 8 optical fibers with 4 fibers transmitting and 4 receiving at either 10 Gb/s or 25 Gb/s.

Base-12 Plug and Play Fiber

Siemon’s Base-12 Plug and Play Fiber Systems include enclosures, modules, adapters, trunk assemblies and jumpers to provide complete end-to-end fiber systems for ultra high-density, high-density and standard-density fiber deployments. Modules and adapters use high-quality ceramic alignment sleeves to deliver tighter tolerances and greater durability than traditional phosphor bronze sleeves for improved fiber-to-fiber mating alignment and wear resistance.

Fiber Optic Cabling

Siemon XGLO Fiber Optic Cabling Systems utilize bend-insensitive laser-optimized multimode fiber and advanced bend-insensitive singlemode fiber to support the very latest fiber applications. Included in the XGLO family is Siemon’s innovative LC BladePatch® Uniboot Fiber Assemblies that ease access and removal in high-density environments and the LightBow™ Fiber Termination System that significantly reduces termination time and improves performance.

Fiber Optic Splicing Solutions

Fast, high performance methods for your single and mass fusion splicing applications. High performance fiber optic connectivity is now a critical component within every network infrastructure. This evolution has driven innovations in a range of areas, and fiber optic splicing is no different.

Passive Optical Network (PON)

Modular, cost-effective, high-performance solutions for distributing voice, video and data to the desktop. Passive Optical Network (PON) is capable of distributing voice, video and data to the desktop over one singlemode fiber, and offers the benefit of extended transmission distances, as well as easy deployment and reduced pathway and conduit space.

LightWays® Fiber Routing System

LightWays is easy to assemble and includes a wide variety of straight duct, elbows, tees, crosses, reducers and innovative outlets for designing a system that meets the precise needs of your data center space. Our innovative fiber optic routing system is fully enclosed to protect the fiber from dirt and dust as it traverses from network distribution to SANs and server areas.

High-Speed Cable Assemblies

A full line of copper and fiber assemblies for high-speed direct attach applications in the data center. Siemon’s comprehensive line of high-performance, high-speed cable assemblies for direct attach point-to-point applications in the data center support up to 100 Gig across an array of application environments.

Independently tested for interoperability with most major equipment manufacturers, our high-speed assemblies are available in a variety of QSFP28, SFP28, QSFP+, SFP+ form factors, including hybrid breakouts and active optical cables. Our cables are competitively priced, available in various lengths, including many 1/2 meter increments and color options, and are all backed by Siemon’s superior technical service and support.

Siemon high-speed cable assemblies are MSA (Multi-Source Agreement) compliant to ensure compatibility across equipment from various vendors.
