●Multi-mode Fiber: Fibers that support many propagation paths or transverse modes are
called multi-mode fibers, generally have a wider core diameter and are used for short-distance
communication links and for applications where high power must be transmitted.
●Single-mode Fiber: Fiber that support a single mode are called single-mode fibers. Single-mode
fibers are used for most communication links longer than 1,000 meters (3,300 ft).
●SFP：small form-factor pluggable , is a compact, hot-pluggable network interface module used for
both telecommunication and data communications applications.
●optical fiber connector: terminates the end of an optical fiber, and enables quicker connection and
disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light
can pass. 4 most common types of optical fiber connectors are SC, FC, LC,ST.
●SC:(Subscriber Connector), also known as the square connector was also created by the Japanese
company – Nippon Telegraph and Telephone. SC is a push-pull coupling type of connector and has a
2.5mm diameter. Nowadays, it is used mostly in single mode fiber optic patch cords, analog, GBIC, and
CATV. SC is one of the most popular options, as its simplicity in design comes along with great
durability and affordable prices.
● LC：(Lucent Connector) is a small factor connector (uses only a 1.25mm ferrule diameter) that has a
snap coupling mechanism. Because of its small dimensions, it is the perfect fit for high-density
connections, XFP, SFP, and SFP+ transceivers.
● FC :(Ferrule Connector) is a screw type connector with a 2.5mm ferrule. FC is a round shaped
threaded fiber optic connector,mostly used on Datacom, telecom, measurement equipment,
single-mode laser.
● ST: (Straight Tip) was invented by AT&T and uses a bayonet mount along with a long spring-loaded
ferrule to support the fiber.
● USB: Universal Serial Bus is a standard that was developed in the mid-1990s that defines cables,
connectors and communication protocols. This technology is designed to allow a connection,
communication and power supply for peripheral devices and computers.
● USB 1.1: Full–Bandwidth USB, specification was the first release to be widely adopted by the
consumer market. This specification allowed for a maximum bandwidth of 12Mbps.
●USB 2.0:or Hi–Speed USB, specification made many improvements over USB 1.1. The main
improvement was an increase in bandwidth to a maximum of 480Mbps.
● USB 3.2: Super Speed USB with 3 varieties of 3.2 Gen 1(original name USB 3.0), 3.2Gen 2(original
name USB 3.1), 3.2 Gen 2x2 (original name USB 3.2) with speed up to 5Gbps,10Gbps,20Gbps
respectively.
