How to Choose the Best FC Fiber Optic Connectors
Understanding Connector Types
Fiber optic connectors terminate the end of a fiber optic cable, allowing it to be plugged into a device. The most common types include SC, LC, ST, and MTP/MPO. SC (Subscriber Connector) connectors are push-pull, while LC (Lucent Connector) are small form-factor connectors often used in high-density applications. ST (Straight Tip) connectors use a bayonet mount. MTP/MPO connectors are designed for multi-fiber applications, crucial for high-speed networking.
Key Specifications to Consider
- Ferrule Material: Typically ceramic (zirconia) or stainless steel. Ceramic is preferred for its durability and precision.
- Polish Type: PC (Physical Contact), UPC (Ultra Physical Contact), and APC (Angled Physical Contact). APC offers the best return loss performance, making it ideal for sensitive applications like FTTx.
- Fiber Type Compatibility: Ensure the connector is compatible with your fiber type (e.g., single-mode OS1/OS2 or multi-mode OM1/OM2/OM3/OM4/OM5).
- Durability and Strain Relief: Look for robust construction and effective strain relief to protect the fiber termination.
Installation and Application
Some connectors are field-installable, requiring specialized tools and training. Pre-terminated cables with factory-installed connectors are often a more reliable and convenient option for most users. Consider the environment where the connectors will be used. For high-vibration or mobile applications, connectors with secure locking mechanisms are beneficial. For data centers, high-density LC connectors are standard due to their small footprint.
