The FC interface is the earliest interface type used in storage area networks. The shell is made of metal, and the interface has threads, which can be fixed well when connected to the optical module (most used on the distribution frame).
The ST interface is a snap-on round type, made of metal, and the interface is a snap-on type, which is often used in optical fiber distribution frames.
The SC interface is a card-connected square type, made of plastic, and is connected by a push-pull connection. The interface can be stuck on the optical module (the most used on router switches).
The PC interface is micro-spherical grinding and polishing.
The LC interface is made of plastic and is used to connect the SFP optical module. The interface can be stuck on the optical module.
The APC interface is at an angle of 8 degrees and is microspherically ground and polished.
The MT-RJ interface is square, with a dual-fiber transceiver integrated in one end.
The SFP interface is a small package GBIC, and the optical fiber used is an LC type.
Compared with other laying cables, the structure of optical fiber is more complicated. The interface types of optical ports of fiber switches are different at different rates, such as the SFP (Gigabit Optical Interface) and SFP plus (10 Gigabit Optical Interface) described above. QSFP plus (40G optical interface) will also be encountered in the project.
To use the 10 Gigabit optical port on the switch, you need to plug in the SFP plus 10 Gigabit optical module. The 10 Gigabit dual-core optical module (dual core is the most commonly used, one receiving and one transmitting) will have two LC interfaces. If two switches are connected, LC-LC fiber jumper is required. If the switch is connected to a patch panel, it depends on the type of patch panel. If the opposite end is an FC patch panel, the jumper needs to be LC-FC patch cord. String.
