Q1: What is the purpose of the inner shutter design?
The inner shutter provides automatic dust protection and prevents laser exposure during connection and disconnection, enhancing safety and performance.
Q2: What’s the difference between the flange and no-flange version?
Flanged adapters are used for fixed panel mounting, while no-flange types are ideal for compact or modular applications where space is limited.
Q3: Is this adapter compatible with both single-mode and multimode fibers?
Yes. It supports both SM (OS2) and MM (OM1–OM5) fibers, depending on the connector polish type and alignment sleeve.
Q4: What alignment sleeve material is available?
Typically ceramic sleeves are used for high precision and low insertion loss, while phosphor bronze options are available for cost-sensitive applications.
Q5: Can I order custom colors or markings?
Yes. LC quad adapters can be customized with color codes (blue, green, beige, aqua) or laser-engraved markings for easier identification.
Q6: How is the product tested before shipment?
Each adapter is inspected for insertion loss (<0.2 dB) and repeatability, ensuring compliance with IEC 61754 and Telcordia GR-326 standards.
Q7: Where is this adapter commonly used?
It’s widely deployed in data centers, patch panels, and distribution frames where high-density LC connectivity is required.
