Answers to common inquiries regarding fiber switches, optical modules, fiber media converters, and other devices, helping you quickly resolve technical issues.
Absolutely. We offer flexible customization services, including special cable lengths, different connector types, and personalized labeling and packaging services.
Consultation (technical specifications, quantity) → Solution & Quotation → Compatibility Test or Sample Confirmation → Contract Signing & Production → Quality Inspection → Delivery & Logistics → After-Sales Support.
PHILISUN strictly adheres to the ISO9001 quality management system. We maintain rigorous control from raw material procurement to final product shipment. All optical communication products undergo 100% performance testing (e.g., insertion loss, return loss, eye pattern). Advanced ERP and MES management systems ensure traceability and reliability.
Standard warranty is typically 1-3 years (per contract). We provide 7×24 hours professional technical support via phone, email, or online service.
From low-speed to ultra-high-speed: 100M/1G/10G/25G/40G/100G/200G/400G, and advanced 800G/1.6T solutions for HPC/Data Centers.
Yes, we do. We offer customized MPO/AOC/DAC cables specifically for HPC platforms like NVIDIA. This ensures perfect matching with the customer’s hardware system in terms of length, bending radius, and firmware coding to achieve optimal performance and compatibility. For details, please refer to our InfiniBand product line.
Yes. All modules support DDM/DOM for real-time monitoring of power, temperature, and voltage, aiding in preventive maintenance and fault localization.
Yes. Our modules are 100% strictly tested in our compatibility lab to ensure stable operation with devices from Cisco, Huawei, Juniper, H3C, NVIDIA, etc..
SM: For long distance (10km–100km, 1310nm/1550nm).
MM: For short distance (typically within 500m, 850nm). Choice depends on distance and bandwidth.
MPO is the generic IEC standard term for multi-fiber connectors. MTP® (US Conec) is a trademark for a high-performance upgraded version of the MPO.

Fiber optic FAQ for project and product decisions
Use this FAQ page to prepare the information PHILISUN needs for accurate product selection, quotation, testing and project support.
How to use this page
For MPO cabling, confirm fiber count, gender, key orientation, polarity method, route length and connected equipment.
For transceivers, confirm host model, speed, reach, wavelength, connector, temperature, coding and DOM/DDM requirements.
For patch cords and pigtails, confirm connector type, polish, fiber mode, cable diameter, color, label and packaging quantity.
For custom projects, provide drawings, port maps, delivery schedule, inspection requirements and any approved sample reference.
If a question involves an existing network, include what is already installed. The same product name can require different polarity, coding, jacket, connector gender or label rules depending on the equipment and route.
What to prepare before contacting PHILISUN
Prepare the target equipment, speed, fiber type, connector, reach or length, quantity, delivery schedule and any test documentation requirement. For custom assemblies, include label rules, packaging groups and whether the order should match a previous approved sample.
