Is multimode fiber considered optical cable
Multimode fiber (MMF) is an optical fiber designed to carry multiple light propagation paths—or modes—simultaneously. This is made possible by its relatively large core diameter, typically 50 or 62. 5 microns, compared to the ~9-micron core in single-mode fiber. The wider core accepts light from. Single mode fiber optic cable is made up of a small diameter glass or plastic core surrounded by cladding, which is a layer of reflective material. This small diameter core, typically around 9 microns in diameter, allows only one mode of light to pass through, resulting in a narrower beam of light. Two main types dominate network design: multimode fiber and single-mode fiber. While they may look similar from the outside, they differ significantly in core size, transmission behavior, distance capability, bandwidth potential, equipment requirements, and overall cost. Although they can do the same job in some instances, the different construction methods make each of them better suited to certain tasks and budgets.

Single-mode dual-fiber connection via a single optical fiber
Single fiber module also called BiDi transceiver or WDM module. It uses WDM technology to realize the bidirectional transmission of optical signals on one optical fiber. Fiber media converters quietly solve a big, practical problem: they bridge copper Ethernet to fiber and extend links far beyond copper's reach. In real networks such as campuses, factories, metro POPs converters let you reuse existing switches and still run fiber for long distance, EMI immunity. Single fiber modules (BiDi) use one fiber for both transmitting and receiving data. They are easier to set up and give steady communication. In fiber optics, the data is sent in the form of light pulses or signals at high speeds and over long distances.
