MPO-MPO Patch Cords
MPO-MPO patch cord is used for signal transmission, both sides are MPO connectors. Common cables are round type, and fiber counts are 12/24/36/48/72/144 cores.

Description
| Parameter Category | Parameter Item | Typical Value/Options | Explanation |
|---|---|---|---|
| Connector Type | MPO Specification | MPO-12, MPO-16, MPO-24 | 12-fiber/16-fiber/24-fiber connectors; MPO-12 (40G) and MPO-24 (100G/400G) are most common. |
| Gender | Male (with guide pins), Female (without guide pins) | Male connectors plug into adapters; Female connectors are used for panel mounting. | |
| Fiber Type | Mode/Grade | Multimode: OM3, OM4, OM5 Singlemode: OS2 |
OM3/OM4 for short-range high-speed (e.g., 100G-SR4); OS2 for long-range (10km+). |
| Fiber Count | 12-fiber, 24-fiber, 32-fiber | Must match transceiver channels (e.g., 100G-SR4 uses 20 fibers out of 24). | |
| Optical Performance | Insertion Loss | Multimode: ≤0.35 dB Singlemode: ≤0.5 dB |
Typical factory-terminated values; field terminations may have higher loss. |
| Return Loss | Multimode: ≥20 dB Singlemode: ≥50 dB |
Singlemode requires higher values to minimize reflections. | |
| Mechanical Properties | Mating Cycles | ≥500 cycles | Complies with IEC 61754-7 standard. |
| Tensile Strength | ≥100N (trunk cable) | Ensures fiber integrity during installation. | |
| Bend Radius | Static: ≥10× cable diameter Dynamic: ≥20× cable diameter |
Prevents signal loss due to excessive bending. | |
| Environmental | Operating Temperature | -20°C to +70°C | Suitable for standard data center environments. |
| Fire Rating | OFNR (Riser), LSZH (Low Smoke Zero Halogen) | Choose based on deployment (e.g., LSZH for confined spaces). | |
| Polarity Scheme | TIA-568 Standard | Type A (Straight-through), Type B (Reversed), Type C (Pair-flipped) | Ensures correct Tx/Rx alignment (Type B is most common). |
| Application | Speed & Distance | Multimode (OM4): – 40G-SR4: 150m – 100G-SR4: 100m Singlemode (OS2): – 100G-LR4: 10km |
Actual distance depends on transceiver and link budget. |
| Transceiver Compatibility | QSFP+, QSFP28, OSFP, etc. |
