When rack-to-rack distances exceed 5 meters, copper direct attach cables hit physical limits. FB-LINK active optical assemblies use 850nm VCSEL laser transmission to maintain signal integrity over longer runs with significantly lower power draw.
Lower thermal load means reduced cooling costs—especially critical when scaling to thousands of ports. Full power specs available in product datasheets.
Optical fiber transmits light signals, inherently immune to electromagnetic interference from adjacent cables or equipment.
Tighter bends enable cleaner cable management in confined spaces—important for high-density ToR deployments.

Q: When should I choose AOC over copper DAC cables?
A: Optical AOC becomes the practical choice when your link distance exceeds 5 meters—copper DAC signal quality degrades beyond this point. AOC also makes sense in dense cabling environments where EMI crosstalk is a concern, or when cable weight and bend radius matter for rack management. For sub-5m intra-rack links, DAC remains more cost-effective. Our engineering team can help you evaluate based on your specific deployment layout.
Q: What custom lengths and jacket materials are available?
A: We manufacture custom lengths from 0.5 meters to 100 meters in 0.5m increments. Jacket options include standard PVC, plenum-rated OFNP for air handling spaces, and LSZH (low smoke zero halogen) for applications with strict fire safety codes. Custom jacket colors are available for volume orders—useful for cable identification in large deployments. Submit your requirements for a quotation.
Q: Are these AOC assemblies compatible with my switches?
A: All FB-LINK optical cable assemblies comply with MSA (Multi Source Agreement) standards, ensuring baseline compatibility with QSFP28, QSFP+, SFP28, and SFP+ ports across vendors. We also program vendor-specific EEPROM codes for Cisco, Arista, Juniper, Dell, HPE, and Mellanox/NVIDIA equipment on request. If you need confirmation for a specific switch model, send us the part number and we'll verify compatibility.
Q: What is the typical lead time for orders?
A: Standard configurations with common lengths typically ship within 3-5 business days from our Shenzhen facility. Custom orders—including non-standard lengths, specific vendor coding, or private-label packaging—require 10-15 business days depending on quantity. For time-sensitive deployments, contact us to check current stock availability and expedited options.
Q: What warranty and testing documentation do you provide?
A: FB-LINK provides a 3-year warranty covering manufacturing defects. Each production lot undergoes automated optical inspection, insertion loss testing, and burn-in cycling before shipment. Test reports with optical power measurements are available on request. For enterprise procurement requiring specific compliance documentation, we can provide certificates of conformance and material declarations.
Q: Do you offer samples before volume purchase?
A: Yes. We provide evaluation samples for qualified projects so you can verify compatibility and performance in your own test environment before committing to volume orders. Sample requests include product datasheets and can be accompanied by test reports. Request samples here with your application details.
