Which of the following connectors is commonly used in data centers for fiber connections?

RJ11
Subscriber Connector (SC)
F-connector
RJ45

The correct answer is: Subscriber Connector (SC)

The Subscriber Connector (SC) is a widely used connector in data centers for fiber connections due to its robust design and ease of use. SC connectors feature a push-pull mechanism, allowing for simple insertion and removal, which is particularly advantageous in high-density environments like data centers where numerous connections are managed. They are also known for their low insertion loss and back reflection, making them ideal for high-performance applications. The SC connector supports a bidirectional data transfer and is compatible with both single-mode and multimode fiber cables, contributing to its popularity in various networking scenarios. In contrast, RJ11 is primarily used for telephone connections and is unsuitable for fiber optic applications. The F-connector is typically utilized for coaxial cables in TV and broadband services, making it irrelevant in fiber optics. RJ45, while integral for Ethernet connections over copper cabling, does not apply to fiber connections. Understanding the specific application of each connector helps in selecting the appropriate type for networking needs, especially in advanced environments like data centers where fiber optics play a critical role.
