Description
MPO-12 Multimode Patch Cord (OM3 / OM4 / OM5), LSZH, Type B
Factory-terminated MPO-12 to MPO-12 multimode patch cord with female-to-female MPO connectors and Type B (crossover) polarity, available in three multimode fiber grades: OM3 (Aqua), OM4 (Violet), and OM5 wideband (Lime green). The 12-fiber ribbon assembly uses bend-insensitive 50/125 µm fiber under LSZH jacket, ready for plug-in between MPO/MTP cassettes, transceivers (QSFP/QSFP28/QSFP-DD SR4) and patch panels in high-density data center parallel optics deployments. Each assembly is 100% factory tested for insertion loss and endface geometry per IEC 61300-3-35.
Available modes: OM3 (10G/40G up to 100 m @ 850 nm), OM4 (10G/40G/100G up to 150 m @ 850 nm), and OM5 wideband (40G/100G SWDM4 up to 440 m, 400G SR4.2 up to 150 m). Choose the mode that matches your transceiver and reach requirements.
Key Features
- Three multimode grades on one product page: OM3 Aqua, OM4 Violet, OM5 Lime green — order the same MPO-12 patch cord at the mode your link needs.
- MPO-12 female-to-female assembly: standard for parallel optics transceivers (no pins on either end; pair with MPO male-to-male trunk cables for full duplex link).
- Type B (crossover) polarity: standard polarity for 40G/100G SR4 direct connection between MPO/MTP cassettes.
- Low insertion loss: MPO multimode ≤ 0.35 dB typical per IEC 61753-1 Grade B.
- High return loss: ≥ 30 dB multimode per IEC 61300-3-4.
- Bend-insensitive 50/125 µm fiber: 7.5 mm minimum bend radius for tight routing inside racks.
- LSZH jacket: OFNR-rated jacket in TIA-568.3-E standard color code per mode (Aqua/Violet/Lime).
- 100% factory tested: insertion loss and endface geometry per IEC 61300-3-35; test report shipped with each assembly.

How to Choose the Right Mode
- Pick OM3 (Aqua) if your link is 10G/40G up to 100 m, or if you are matching legacy OM3 plant. Lowest cost.
- Pick OM4 (Violet) if your link is 40G/100G up to 150 m, or if you want headroom for 100G SR4 today and OM5 migration later.
- Pick OM5 (Lime green) if you are deploying SWDM4 transceivers (BiDi / SWDM) for 40G/100G up to 440 m, or 400G SR4.2 over a single MPO-12.
Compliant with IEC 61753-1, IEC 61300-3-35, TIA-568.3-E and ISO/IEC 11801-1 OM3/OM4/OM5. Each assembly ships with serial number, test report, mode-specific jacket color, and length-specific labeling.
