DESCRIPTION
The SC to SC APC/UPC SM Simplex Plastic Shutter Adapter is designed for secure, reliable, and clean optical connections in FTTH, telecom, and data center applications.
Featuring a built-in shutter, it automatically covers the port when not in use, protecting against dust and preventing accidental eye exposure to laser light.
Available in APC (green) and UPC (blue) versions, this adapter supports single-mode simplex connections and can be configured with or without a flange for installation flexibility. Its precision ceramic alignment sleeve ensures minimal insertion loss and consistent optical performance in demanding environments.
FEATURE DETAILS

- Shutter Protection Design: The built-in shutter prevents dust accumulation and laser exposure, ensuring safer and cleaner fiber interfaces.
- APC/UPC Compatibility: Available in both APC and UPC polish types for different optical return loss requirements.
- Flange Options: Flanged types are ideal for panels and wall boxes, while flange-less versions suit compact enclosures.
- High-Precision Ceramic Sleeve: Provides accurate fiber alignment, stable connection, and minimal signal loss even after repeated mating cycles.
- Durable and Lightweight Construction: Plastic housing offers excellent strength-to-weight ratio and long-term reliability in indoor or semi-protected environments.

FAQ
Q1: What is the function of the shutter in this adapter?
A1: The shutter prevents dust ingress and shields users from direct laser light exposure when the port is open.
Q2: What’s the difference between APC and UPC versions?
A2: APC (green) uses an 8° angled polish for low reflection, while UPC (blue) uses a flat polish for general connections.
Q3: Can I choose with or without a flange?
A3: Yes. Flanged types suit ODF or panels, and flange-less types are ideal for compact enclosures.
Q4: Is this adapter suitable for single-mode or multimode fibers?
A4: It is specifically designed for single-mode (SM) fiber applications.
Q5: How long is the service life of the adapter?
A5: It supports over 1000 mating cycles without significant performance degradation.
Q6: Does it comply with international standards?
A6: Yes, it meets IEC 61754-4 and RoHS standards for safety and reliability.
