Fiber optic networks rely on fiber patch cords

The colorful connectors that link devices like switches, routers, and servers. But have you ever wondered what the cable color means? It serves as a clue to the fiber type, mode, and supported speed
Let’s delve into the world of multimode fiber (OM1, OM2, OM3, OM4, and OM5)
◼ OM1:with a larger core (62.5 microns), excels at short distances and moderate speeds (1 Gbps up to 300 meters, 10 Gbps up to 33 meters).
◼ OM2:a thinner core (50 microns) and supports faster speeds over longer distances (1 Gbps up to 550 meters, 10 Gbps up to 82 meters).

◼ OM3:a 50 microns core but with higher bandwidth (2000 MHz*km). Conquer distances with 10 Gbps up to 300 meters or into higher speeds (40/100 Gbps up to 100 meters).

◼ OM4: boasts an impressive 4700 MHz*km bandwidth. This translates to even better performance, especially for 10 Gbps (up to 550 meters) and 40/100 Gbps (up to 150 meters) networks.

✳ Lime Green:
◼ OM5 : it utilizes 50 microns core and embraces a different approach: Short Wavelength Division Multiplexing (SWDM). This allows for multiple wavelengths on a single cable, boosting capacity and flexibility, making it perfect for data centers.

⭕ Ethernet Standards and Multi-Mode Fiber Categories
