DESCRIPTION
The LC to LC APC Duplex Low Profile Fiber Adapter without Flange is designed for space-saving, high-density fiber optic applications where secure and precise LC connections are required.
This duplex adapter supports two fibers (Tx/Rx) simultaneously and is available in both UPC (blue) and APC (green) polish types, providing flexibility for different single mode network requirements. Its low-profile, flangeless design allows for compact installations in high-density data centers, distribution frames, and patch panels.
With a zirconia ceramic alignment sleeve, it ensures low insertion loss, excellent return loss, and long-term reliability, making it suitable for demanding telecom and enterprise applications.

FAQ
Q1: What is the difference between UPC and APC adapters?
APC (green) uses an angled polish that provides very low back reflection, making it ideal for high-precision optical systems.
Q2: Why use a low-profile, flangeless adapter?
It is designed for high-density applications, saving space in patch panels and distribution frames.
Q3: Can this adapter be used with multimode fibers?
This specific model is optimized for single-mode (UPC/APC) connections and is not intended for multimode fiber.
Q4: How many times can the adapter be re-used?
It is designed to support at least 1,000 mating cycles while maintaining stable optical performance.
Q5: Where is this adapter most commonly used?
It is commonly used in data centers, telecom systems, FTTH networks, and enterprise cabling infrastructures.
