A systems administrator is installing several new high-density blade servers that utilize SFP+ transceivers for 10GbE network connectivity. To maximize the number of connections in the limited rack space, the network switch is also equipped with high-density SFP+ ports. Which of the following fiber optic connector types should the administrator use for the patch cables?
The correct answer is the Lucent Connector (LC). LC connectors have a small 1.25mm ferrule, which makes them ideal for high-density applications, such as blade servers and switches populated with Small Form-factor Pluggable (SFP/SFP+) transceivers.
The Subscriber Connector (SC) is incorrect because it uses a larger 2.5mm ferrule and is not suitable for high-density installations.
The Straight Tip (ST) connector is an older type that uses a bayonet-style locking mechanism and is not used in modern high-density SFP+ deployments.
The Mechanical Transfer Registered Jack (MTRJ) connector is also a small form-factor connector but is far less common than the LC connector and is not the standard interface for SFP+ transceivers.
