RCDD · Question #348
Which of the following is NOT a type of connector for optical fiber?
The correct answer is D. S/FTP. S/FTP is a shielded copper twisted-pair cable classification, not an optical fiber connector type.

Why each option
S/FTP is a shielded copper twisted-pair cable classification, not an optical fiber connector type.
LC (Lucent Connector) is a small form-factor fiber optic connector widely used in data center and enterprise fiber deployments.
ST (Straight Tip) is a bayonet-locking fiber optic connector that was common in legacy multimode fiber installations.
SFF (Small Form Factor) refers to a class of compact fiber optic connectors, including types such as LC and MT-RJ.
S/FTP stands for Screened/Foiled Twisted Pair and is a copper cable shielding designation defined in ISO/IEC 11801, not a fiber optic connector. Fiber optic connectors are physical termination hardware identified by their body design and coupling mechanism, such as LC, SC, and ST. S/FTP describes the shielding construction of a copper cable and has no role or definition in fiber optic connectivity.
SC (Subscriber Connector) is a push-pull latching fiber optic connector widely used in telecommunications and structured cabling.
