GBIC modules are hot swappable and contain ID and system information for the switch. GBIC was superseded by the small form-factor pluggable transceiver (see SFP).
Which of the following are features of multimode fiber cable?Multimode fiber optic cable has a large diametral core that allows multiple modes of light to propagate. Because of this, the number of light reflections created as the light passes through the core increases, creating the ability for more data to pass through at a given time.
What are the characteristic features of the 100basetx Ethernet standard?Main characteristics of 100Base-TX FastEthernet are listed below. Operating speed of FastEthernet is 100 Mbps. Similar to other Ethernet standards, 100Base-TX uses baseband signals to transfer data. FastEthernet supports a maximum distance 100 meters between the network switch and the client computer.
What are the characteristic features of the RJ45 connector?RJ45 plugs feature eight pins to which the wire strands of a cable interface electrically. Each plug has eight locations spaced about 1 mm apart into which individual wires are inserted using special cable crimping tools. The industry calls this type of connector 8P8C, shorthand for eight position, eight contact.
