Multi-Mode

Multi-Mode Fiber Patch Cables — OM1 / OM2 / OM3 / OM4 • LC / SC / ST

Choose the exact multimode fiber jumper you need by fiber grade (OM1–OM4), connector type (LC/SC/ST), and polarity (Simplex/Duplex). These patch cables are ideal for switch-to-panel, server-to-switch, lab/test benches, and general LAN / SAN fiber interconnects.

  • Match the OM type: Use the same OM grade as your installed backbone (OM3/OM4 for most modern 10G/40G/100G MMF links).
  • Pick the connectors: LC is most common on modern optics; SC and ST are often found on legacy gear and patch panels.
  • Simplex vs Duplex: Simplex = 1 strand; Duplex = 2 strands (Tx/Rx pair).
Quick selection tips
  • Most common today: OM3/OM4 with LC-LC duplex.
  • Legacy panels/gear: SC or ST ends are common match what’s already installed.
  • When in doubt: Match the OM type and connector style to your patch panel and transceivers.
  • See the chart at the bottom of the page for an abbreviation breakdown.

Abbreviation Meaning
MM / MMF Multi-Mode (Multimode) Fiber — typically used for short-to-medium distance LAN/SAN links.
OM1 Optical Multimode grade 1 (legacy). Commonly 62.5/125 µm; often seen with orange jacket.
OM2 Optical Multimode grade 2. Commonly 50/125 µm; often seen with orange jacket.
OM3 Laser-optimized multimode (LOMMF). Commonly aqua jacket; used for higher-speed links.
OM4 Enhanced laser-optimized multimode. Commonly aqua/violet; supports longer reach than OM3 at higher speeds.
LC Lucent Connector — small form factor, modern standard on most transceivers/SFPs.
SC Subscriber/Standard Connector — larger push-pull connector, common on panels and legacy equipment.
ST Straight Tip — bayonet-style twist-lock connector, frequently found in older installations.
Simplex Single-strand cable (1 fiber). Used for single-fiber applications or special optics/media converters.
Duplex Two-strand paired cable (2 fibers) for Tx/Rx on most standard multimode links.
2mm / 3mm Approximate cable jacket diameter. 2mm is slimmer/lighter; 3mm is more robust for general patching.
Aqua / Orange / Violet Common jacket colors used to help identify fiber grade (orange often OM1/OM2; aqua OM3/OM4; violet frequently OM4).
