Frequently Asked Questions
Sourcing, compatibility and cooperation questions we are asked most often
Standard models are held in stock and sample orders are accepted, so you can test before committing to volume. Small-batch and mixed-model orders are both supported, and neutral packaging is available on request.
Yes. Our transceivers are MSA compliant, plug-and-play and tested for interoperability with mainstream switch and router brands. Tell us the exact equipment model and we will confirm the matching part number before you order.
We do. Neutral packaging, custom labels, logo printing, specification tailoring and SKD/CKD cooperation models are all available, backed by engineers with 16 years in optical R&D who can also support custom firmware and diagnostics requirements.
Every unit goes through incoming inspection, in-process control and final factory testing under an ISO-based quality system, with 3D interferometer inspection on fiber assemblies. All products meet IEC 60825-1 Class 1 laser safety. Our engineering team supports debugging and troubleshooting after delivery.
Standard stock models typically ship within 3-7 days after order confirmation. Customised or high-rate modules depend on configuration and volume; we confirm the exact lead time together with the quotation.
