Markings of Huijue Multimode Optical Cables

Fiber and communications infrastructure knowledge brief Published 04 Sep 2023

Prepared for preliminary research by the ROGER FIBRE knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Huijue multimode optical cables are marked with standardized jacket colors, fiber type identifiers (OM1–OM5), fiber counts, and individual fiber color sequences according to TIA/EIA standards.

Outer Jacket Color and Fiber Type

The outer jacket color of a multimode cable indicates the fiber type and performance level. Common color conventions include: Orange: OM1 (62. 5/125 µm)Gray: OM2 (50/125 µm)Aqua: OM3 (50/125 µm, laser-optimized)Aqua or Violet: OM4 (50/125 µm, higher bandwidth)Lime Green: OM5 (50/125 µm, SWDM-capable) These colors help technicians quickly identify the cable type during installation or maintenance, though some manufacturers may use custom colors with printed legends for hybrid or legacy cables.

Fiber Count Markings

Huijue multimode cables are typically marked with the number of fibers on the jacket, such as “12F” for 12 fibers or “24F” for 24 fibers. This marking ensures accurate identification of the cable's capacity and simplifies network planning and troubleshooting.

Inner Fiber Color Sequence

Inside the cable, each individual fiber is color-coded following the TIA-598 standard 12-color sequence: BlueOrangeGreenBrownSlateWhiteRedBlackYellowVioletRoseAqua For cables with more than 12 fibers, the sequence repeats for fibers 13–24, 25–36, and so on. This systematic approach allows technicians to trace and terminate fibers accurately.

Connector and Boot Color

Connectors and boots are also color-coded to indicate fiber mode and polish type: Blue boot: Single-mode fiber with UPC polishGreen boot: Single-mode fiber with APC polishAqua boot: Multimode fiber (OM3/OM4)Violet boot: Higher-performance OM4 variantLime boot: OM5 multimode fiber These markings help ensure proper mating and minimize signal loss during installation.

Additional Markings

Some Huijue multimode cables may include: Printed legends specifying fiber distribution in hybrid cables (e.g., “8 x 50/125, 4 x 62. 5/125”)Manufacturer name or logoCompliance standards (TIA/EIA, ISO/IEC)Date codes or batch numbers for traceability These markings collectively ensure accurate identification, compliance, and efficient maintenance in complex network environments. By following these standardized markings, technicians can quickly identify fiber types, trace connections, and maintain high-performance multimode networks with minimal errors.
