MTP/MPO FIBER PATCH CORD TEST
MTP/MPO fiber optic patch cord connector end face inspection: In order to ensure that the fiber optic connector has qualified or higher performance, the International Electrotechnical Commission (IEC) has developed the IEC 61300-3-35 standard to define whether the connector end face is qualified. The end face of the MTP/MPO patch cord connector is divided into four areas: core area, cladding area, glue edge area and ferrule surface. It has requirements for scratches and blemishes in each area of the connection. Scratches represent permanent linear surface features. Defects include all detectable non-linear features on the optical fiber, including particles, other debris, pits, debris, edge chipping, etc. The cleaner the end face, the better the cable quality.
| Area name | Scratches | Flaw |
| Core area | No scratches | Flawless |
| Cladding area | ≥3µm is not allowed; ≤3µm is not restricted | Not allowed>5µm; 2-5µm allowed in 5 places; ≤2µm unlimited |
| Rubber edge area | Unlimited | / |
| Ferrule surface | Unlimited | Not allow ≥10µm |
3D inspection: Whether the fiber optic line can be successfully connected depends on the quality of the fiber, but the quality of the fiber jumper is determined by the size of the connector itself. If the size is not strictly controlled, the network cannot operate reliably for a long time. 3D detection defines the parameters of the MTP/MPO fiber optic patch cord connector, as shown in the following:
| Parameter | Claim |
| Fiber X Angle (SX) | -0.2~0.2° (PC/APC) |
| Fiber Y Angle (SY) | ±0.2° |
| Fiber X Radius (RX) | ≥2000 mm |
| Fiber Y Radius (RY) | ≥5 mm |
| Fiber bending radius (RF) | ≥1 mm |
| Fiber height (H) | 1000~3000 nm |
| Maximum fiber height difference (HA) | 500 nm |
| Maximum adjacent height difference (HB) | 300 nm |
| Coplanarity | ≤2000 nm |
| Core inclination | -100nm~+200 nm |
