These cables are designed to carry multiple light rays simultaneously, thanks to their larger core size compared to single-mode fibers. This characteristic enables them to transmit data over short to medium distances with impressive efficiency. Multimode Fiber (MMF) has a core diameter, typically 50–100 micrometers, has ability to transfer multiple modes of light through the fiber core, uses lower-cost electronics (LED, VCSEL) operates at the 850 nm and 1300 nm wavelength and is used for short distance interconnections (up to 550m). Featuring OM3/OM4 multimode, single-mode, armored, and waterproof designs for reliable performance. Identified by its distinctive aqua jacket, OM4 fiber offers increased bandwidth, supporting data speeds of 10 Gbps, 40 Gbps, and even 100 Gbps over. This larger core allows easier light injection and lower-cost optical sources (LEDs and VCSELs), making multimode fiber the cost-effective choice for.
