Fiber optic patch cords come in various colors, aiding in connector type identification. Fiber color code is a standard specification for color coding of fiber optic cables, developed by the Telecommunications Industry Association (TIA). Note in the chart above that OM5 has the same modal bandwidth as OM4 @ 850 nm. The main difference between the two options is that OM5 is designed specifically to handle Short Wave Division Multiplexing, which transmits four channels on one duplex. OFNR (Riser) rated jacket with Kevlar yarn, and are factory terminated resulting in uncompromised performance. GT-SCSCDM4A-xM fiber optic patch cords are ideal for short distance patching. 10 Gb (40 Gb/100 Gb) OM4 Multimode fiber optic patch cables are 50 micron diameter for the actual glass core. The glass is a higher grade than normal 50/125 cables. You should ensure that you purchase patch. Multimode Fiber Patch Cable Color Coding – What Does It Mean Ever been curious about why certain cables are colored differently? In fact, when it comes to multimode fiber patch cables, these colors have a particular significance. 10-Gbps compliant per IEEE 802.
