FAQ

1. What specifications can be customized?

We can customize the operating wavelength, port type, splitting ratio, packaging, fiber sheath, pigtail length, and connector type according to project requirements. For equipment manufacturers, system integrators, and experimental platform customers, we can support sample verification, engineering specification confirmation, and batch project delivery, reducing the pressure on customers for subsequent model switching and material preparation.

2. How do you ensure product quality and batch consistency before shipment?

As an engineering-driven passive optical component manufacturer, Gracyfiber was founded in 2014. Our team has over 25 years of industry experience and a manufacturing facility of over 2,000㎡, focusing on PM components, WDM solutions, fiber arrays, and precision photonic components. The product page indicates certifications of ISO, CE, and RoHS, with an MOQ of 100pcs. Before shipment, we can conduct tests on insertion loss, splitting ratio, extinction ratio, return loss, port definition, connector quality, and appearance, supporting customers' quality consistency requirements from sample verification to batch delivery.
