| Operating Wavelength | nm | 1550 |
| Operating Bandwidth | nm | ±15 |
| Insertion loss | dB | ≤7.5 |
| Max. Excess Loss | dB | ≤1.2 |
| Extinction Ratio | dB | ≥20 |
| Return Loss | dB | ≥50 |
Q1: What are the splitting ratio and operating wavelength of this 4×4 PM Coupler?
A: The standard splitting ratio of this product is 25:25:25:25, the operating wavelength is 1550nm, and the operating bandwidth is ±15nm. It is suitable for uniform power distribution applications in C-band polarization-maintaining fiber systems.
Q2: What are the main performance advantages of this product?
A: This product uses Corning Panda Fiber, featuring low insertion loss, high extinction ratio, high return loss, and high directivity. Its insertion loss is ≤7.5dB, maximum additional loss is ≤1.2dB, extinction ratio is ≥20dB, return loss is ≥50dB, and directivity is ≥50dB, which can improve polarization stability and transmission reliability in multi-port systems.
Q3: Does this 4×4 Filter PM Coupler support customization?
A: Customization is supported. Customers can choose the fiber length, connector type, fiber sheath, and packaging form according to their needs. The standard fiber length is 1.0±0.1m, and the connector can be FC/APC, FC/UPC or other customized types; the connector key is aligned with the slow axis by default, which facilitates the integration of the polarization-maintaining system.
