This product is a fibre optic network cable from the brand HPE, type CPNT, with manufacturer number QK732A. It is an OM4 multi-mode cable with a length of 1 metre, specifically designed for use in Fibre Channel networks. The cable features two LC multi-mode male connectors at both ends and is intended for use in high-performance storage systems and server environments. The technology is based on fibre optics, with OM4 standardisation ensuring high bandwidth and signal integrity, particularly at high transmission rates and over longer distances. The use of OM4 fibre enables better bend radius resistance and signal transmission compared to OM2 and OM3, simplifying maintenance and installation and reducing downtime.

Applications

The cable is designed for use in specific HP systems, including the SN6000 series of stackable Fibre Channel switches, including variants with single- and dual-power systems, as well as SN6000B models with 16 Gb/s and various port configurations (24- or 48-port). It is also compatible with HP ProLiant DL360e Gen8 servers in Entry and Performance configurations. Additionally, it is recommended for HP StorageWorks 8/20q Fibre Channel switches and the 8Gb Simple SAN Connection Kit. The application is in SAN environments (Storage Area Networks), where reliable and fast data transmission between servers and storage systems is required.

Features and Equipment in Detail

The cable features two individual fibre optic strands, each fitted with an LC connector. The LC connector is a standard in data communication and enables a compact and secure connection, particularly in dense rack installations. The use of OM4 fibre provides a bandwidth of 3000 MHz·km, ensuring high data rates and low signal loss. The bend radius resistance of the fibre reduces the risk of breaks or signal interference during tight bends, facilitating installation in confined racks or complex cabling situations.

Technology Explained Simply

OM4 technology is an advancement of multi-mode fibre optics, optimised for high data rates and longer transmission distances. Compared to OM2 and OM3, OM4 offers higher bandwidth and improved signal transmission characteristics, which is particularly beneficial at 10 Gb/s and higher speeds. The fibre is designed to avoid significant signal loss even under tight bends, increasing operational reliability. The LC connectors are standardised and allow for quick and secure connections without additional tools.

Compatibility and Accessories

The cable is specifically developed for the mentioned HP products, including SN6000 and SN6000B switches, as well as ProLiant DL360e Gen8 servers. It is part of the HP PremierFlex cable series, designed for improved bend radius resistance and signal integrity. Compatibility with existing OM2 and OM3 installations is ensured by OM4 standardisation, allowing the cable to be used in existing infrastructures without modifications.

Installation and Mounting

Installation is performed by simply plugging the LC connectors into the corresponding device ports. The cable connection is tool-free and does not require additional adapters or converters. The bend radius resistance of the fibre allows for flexible placement, even in tight racks or complex cabling scenarios. The length of 1 metre is suitable for short connections within a rack or between adjacent devices.

Operational Advantages

The use of OM4 fibre ensures high signal quality and minimises downtime due to signal interference. Bend radius resistance reduces the risk of damage during installation and maintenance. Compatibility with existing OM2 and OM3 systems enables gradual infrastructure modernisation without complete replacement. The LC connectors ensure a secure and tight connection, increasing operational reliability.
