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.

| 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). |
