As shown in the figure below, but MPO is a high-density optical fiber connector

PC is the lapping method of optical fiber end face

LC (lucent connector): small square port, commonly used to connect the SFP optical mole and the pre terminated mole box

SC (subscriber cable): card type square port, commonly used in optical fiber transceiver and GBIC optical mole

FC (ferrule contact): round with thread, Commonly used in optical fiber distribution frame

st (straight tip): round bayonet, commonly used in optical fiber distribution frame

MPO (multi fiber push on): precision mold molding in MT pin, used in high-density applications

PC APC UPC is as follows:

PC (physical contact), physical contact. The surface of PC is ground and polished, and the surface of insert core is ground into a slight spherical surface

UPC (ultra physical contact), and the super physical end face. The end face of UPC connector is not completely flat, there is a slight arc

APC (angled physical contact), the inclined plane is in physical contact, and the end face of optical fiber is usually ground to 8 ° Bevel

insertion loss: the typical insertion loss of PC, UPC and APC connectors should be less than 0.3dB (larger value), and the typical value is generally less than 0.2db. It is easier for UPC / PC connectors to achieve low insertion loss

return loss: the return loss of APC connector is usually better than that of UPC connector, and the return loss of PC is - 45dB. The return loss of UPC is generally - 50dB (or even higher). The return loss of APC instry standard is - 60dB

FC connector

FC is one of the most common connection equipment in single-mode network. It also uses a 2.5mm ferrule, but some of the early FC connectors were designed with ceramic built-in stainless steel ferrules. At present, FC has been replaced by SC and LC connectors in most applications
FC is the abbreviation of ferrile connector, which indicates that the external reinforcement is metal sleeve and the fastening method is screw buckle. The circular threaded joint is a metal joint, and the pluggable times of the metal joint are more than that of the plastic joint. Generally used in telecommunication network, a nut is screwed to the adapter

disadvantages: after the connector is inserted, there is a bayonet fixed half circle, which is easy to break

development materials

optical fiber interface is a physical interface used to connect optical fiber cables. There are usually SC, St, FC and other types, which are developed by NTT company of Japan. FC is the abbreviation of ferrale connector. Its external reinforcement method is metal sleeve, and the fastening method is screw buckle. St interface is usually used for 10base-f, SC interface is usually used for 100base FX

There are differences between FC / PC connector and FC connector, such as different environment, different back reflection and different adjustment

FC / PC connector: FC / PC connector is a narrow port for single mode or polarization maintaining fiber, which is used in strong vibration environment

FC connector: FC connector is used in the environment of weak vibration, and it is a narrow port for single-mode optical fiber

FC / PC connector: FC / PC connector has ceramic insert with pre rounded corner, which can rece back reflection

2. FC connector: FC connector has no ceramic insert with pre rounded corner and strong back reflection

The FC / PC connector pin is continuously adjustable, and can be accurately aligned with the axis of polarization maintaining fiber. Once aligned, a drop of strong glue can be applied to the back of the joint to lock it in place

2. FC connector: the FC connector pin is not continuously adjustable and cannot be accurately aligned with the axis of polarization maintaining fiber

just go to the first or the second one

9. FC / PC FC / UPC FC / APC can be connected in a mixed way, and the signal attenuation will not be great. According to the national standard, the insertion loss should be less than 0.5dB. The application mainly depends on the type of adapter. Generally, FC is used in ODF, SC is used in optical port, and ST is used in LAN and broadcasting
PC -- the end face of the pin body is the physical end face; UPC -- the end face of the pin body is a super physical end face; APC type: the end face of the pin body is an angular physical end face; The difference is that the return loss is PC ≥ 40dB, UPC ≥ 50dB and APC ≥ 60dB.
