OM4 patch cables take all the benefits of OM3 fiber and increase the transmission bandwidth up to 40gbs, and in some cases 100gbs. OM4, like, OM3, is laser-optimized to give optimum performance and reliability. Unlike other old fiber types, OM4 has a higher attenuation that helps create lower losses over greater distances.

Fiber optic cabling is the medium of choice for longer distance and challenging cabling runs. These cables are thinner than copper patch cords and immune to EMI (Electromagnetic Interference) making them perfect for riser runs and uplink cables. There are two basic types of fiber cabling, single-mode and multi-mode. The cables listed here are multi-mode, but a special version which is laser optimized. These cables are manufactured using a process that eliminates manufacturing anomalies and conditions which cause the glass cores to be prone to modal dispersion when the transmission distance is great. Modal dispersion is the optical equivalent to EMI and causes confusion at the receiving end. The binary 1's and 0's cannot be differentiated. Inside these cables you will find three basic layers. Starting from the inside, you have the core which is surrounded by the cladding. Both are protected with the jacket on the outside. Multi-mode cables have a thicker "core size". The core size is simply the thickness of the optical fiber inside the cladding. The cladding is material that surrounds that core which basically serves as the boundary for the signal, keeping the light refined to the core and not allowing it to escape. The thicker the core size, the more refraction the signal exhibits, the more signal degradation that occurs and the shorter the distance an intelligible signal can transmit. For example, these cables are 50/125. 50 is the diameter of the core, and 125 is the diameter of the cladding, both in micrometers. Lastly, the jacket is the part of the cable you see. This layer protects the cable and provides easy identification based on its color.


LC connections allow higher density applications based on its smaller diameter. The LC connection, commonly referred to as Lucent Connection, Little Connector or Local Connector, is commonly used today for uplink modules and other devices. This connector is a "snap" type, has a ferrule diameter of 1.25mm and defined by IEC 61754-20.

SC connectors, commonly referred to as Subscriber Connectors, Square Connectors or Standard Connectors, are a larger, older connection type found in Cisco GBIC's. The design is rectangle allowing a higher density installation compared to even older, legacy fiber end types. The connector is a "push-pull" type, has a ferrule diameter of 2.5mm and defined by IEC 61754-4.

Uniboot fiber optic cables have two fibers carried through a single jacket with a lower profile boot, reducing the size and surface area of the cables when compared to standard fiber optic cables, but continuing to provide the reliable performance from industry standard connectors. Uniboot fiber cables reduce cable management requirements and allow for better airflow.

Push-Pull Tab connector fiber optic cables have a special tab that will allow easy insertion and removal of the connector without the need to access the boot or connector. The slim, low profile uniboot design allows this high-density installation cabling to be used with minimal cable management and save space in your network setup.
