Q1: What is the standard warranty period for HYTOPTODEVICE optical modules?
A:We offer a 5-year limited warranty on all our high-performance optical modules, including SFP, SFP+, and 100G/200G/400G/800G optical transceivers. This covers any defects in materials or manufacturing under normal operating conditions.

Q2:How does HYTOPTODEVICE ensure the quality of fiber optical transceiver?
A: Unlike other manufacturer of optical modules that only assemble parts, HYTOPTODEVICE builds TOSA, ROSA, and BOSA from the ground up. Our skilled technicians perform high-precision alignment and rigorous performance testing at the component level to ensure the highest reliability for the "heart" of every module.

Q3: Are your optical modules compatible with major switch brands like Cisco or Juniper?
A: Yes. We provide a 100% Compatibility Guarantee. We maintain a comprehensive compatibility lab to test and code our modules for seamless integration with major brands, including Cisco, Arista, Juniper, and more. If you encounter coding issues, we offer free remote technical support.

Q4: What should I do if my optical module is Dead on Arrival (DOA)?
A: We offer an expedited replacement policy for DOA items. If a module fails, please contact our support team with the RMA. Once verified, we will prioritize sending a replacement to minimize your network downtime.

Q5: Does the warranty cover damage caused by dust or contamination?
A: The warranty does not cover laser end-face damage caused by improper cleaning or failure to use dust caps. Since optical sub-assemblies are extremely sensitive, we provide professional handling guidelines with every shipment to help you maintain optimal performance.

Q6: How do I request an RMA (Return Merchandise Authorization)?
A: To start an RMA request, please email our support team with your Order Number, Product S/N, and a description of the issue. Our engineers will perform a remote diagnosis first. If the hardware is faulty, we will issue an RMA number for the return process.
