Fibre Channel is a high-speed network technology primarily used for storage area networks (SANs) and other data storage applications. It enables the transfer of large amounts of data over long distances with low latency. Fibre Channel networks use various types of cable connectors, each designed for specific purposes. Here are the most common cable connector types used in Fibre Channel networks:
- LC Connector:
- Description: The LC (Lucent Connector) is a small, square-shaped connector with a push-pull mechanism. It uses a 1.25mm ceramic ferrule to align and connect fibers.
- Usage Example: LC connectors are commonly used in data centers and enterprise networks for high-density applications. They are used with single-mode and multimode fiber optic cables and provide excellent performance for both short and long-distance connections.
- Bandwidth: LC connectors support various Fibre Channel speeds, including 1Gb, 2Gb, 4Gb, 8Gb, 16Gb, 32Gb, and 128Gb, depending on the specific Fibre Channel generation.
- SC Connector:
- Description: The SC (Subscriber Connector) is a square-shaped connector that uses a push-pull mechanism for connection. It features a 2.5mm ceramic ferrule for aligning and joining fibers.
- Usage Example: SC connectors were widely used in the early days of Fibre Channel networks and are still commonly employed in some installations. They are suitable for both single-mode and multimode fiber cables and find applications in data centers, telecommunication networks, and other high-speed connectivity environments.
- Bandwidth: SC connectors support various Fibre Channel speeds, including 1Gb, 2Gb, 4Gb, and 8Gb.
- FC Connector (also known as FC-PC or FC-PC2):
- Description: The FC (Fiber Channel) connector is a round, threaded connector similar to a BNC connector. It uses a 2.5mm ceramic ferrule for fiber alignment and a screw-on coupling mechanism for secure connections.
- Usage Example: FC connectors are commonly used in Fibre Channel networks for connecting devices such as switches, storage arrays, and servers. They are mainly used with multimode fiber optic cables in SAN environments.
- Bandwidth: FC connectors support various Fibre Channel speeds, including 1Gb, 2Gb, 4Gb, and 8Gb.
- MPO/MTP Connector:
- Description: The MPO (Multi-Fiber Push-On) or MTP (Multi-fiber Termination Push-on) connector is a multifiber connector with multiple fibers housed in a single rectangular ferrule. It allows for easy and quick connections.
- Usage Example: MPO/MTP connectors are commonly used in high-density data center environments and applications where fast and reliable connections are required. They are often used for parallel optical links in Fibre Channel networks.
- Bandwidth: MPO/MTP connectors support higher Fibre Channel speeds, including 16Gb, 32Gb, 64Gb, and 128Gb.
It’s important to note that the bandwidth capabilities of these connectors are dependent on the specific Fibre Channel generation, as well as the type and quality of the fiber optic cables used. The bandwidth mentioned above represents common speeds supported by each connector type, but newer Fibre Channel generations might support higher speeds.
Fibre Channel networks utilize various cable connector types such as LC, SC, FC, and MPO/MTP connectors, each offering specific advantages and applications. The selection of a connector type depends on factors such as network requirements, installation environment, and available equipment.
