ℹ️
The 16-fibers (MPO-16 or MTP-16) connector is a high-density fiber optic connector designed for 400G and 800G Ethernet applications in modern data centers. It features a single row of 16 fibers, utilizing an offset keying mechanism to prevent accidental mating with standard 12-fiber (Base-12) connectors. These connectors are essential for parallel optics, such as 400G-SR8 and 800G-SR8, providing higher data capacity and improved bandwidth.
📏 Capacity
16 fibers per connector in a single row.
🏙️ Density
Offers superior density compared to traditional 12-fiber connectors, utilizing a similar footprint to allow 16 times higher density in some applications.
🚀 Applications
Ideal for 400GBASE-SR8, 800G QSFP-DD/OSFP DR8, and AI/ML data center links.
🔄 Polarity & Type
Typically features Type B polarity (or A/C) for direct connection to transceiver lanes, frequently using APC (Angled Physical Contact) for low insertion loss.
✅ Standards Compliance
Complies with IEC 61754-7, TIA/EIA 604-5, and Telcordia GR-1435-CORE.
🔌 Connector Variants
Available in female (no pins) or male (with pins) versions, often in Single-mode G657A1, OM1, OM2, OM3, OM4 or OM5 (Multimode).
🛡️ Durability
Supports high-speed, low-loss connections with options like 0.65dB standard IL or 0.35dB elite IL.
