What does the GE SFP LC connector SX transceiver on the Cisco switch mean
From the model point of view on the label, the “GE” refers to the Gigabit Ethernet; “SFP LC connector” means that this Cisco switch supports the SFP transceiver with LC interface; and “SX” says that this SFP transceiver should be the short transmission distance multi-mode fiber optic transceiver.
If you would like to buy the related fiber optic transceiver for your switches, it will convenient for you to choose the suitable module according to this knowledge.
SOPTO supplies fiber optic transceivers like “GE SFP LC connector SX transceiver”, which are compatible with Cisco and other brands. Any demand, please feel free to contact.
XENPAK is an important step in the evolution of the optical modules. The XENPAK architecture provides a XAUI interface for the Media Access Controller.Compared with not hot-pluggable modules, XENPAK modules is very attractive. But is can’t meet some important market demand. The power consumption of XENPAK is usually 10W, which will cause a certain influence to the structure size because it increase the cost of manufacturing printed circuit board and reduce the precious line space.
X2 modules also adopt the XENPAK electrical interface, but there are a few local exceptions. X2 offers a 4bit port address space, a bit less than XENPAK. X2 also reduces the number of power supply pin. In the aspect of optical technology, X2 supports 10GbE, OC192 synchronous optical network, 10GFC and other standards.
10G small hot-pluggable XFP module is different from the XENPAK architecture and its 4-channel interface. XFP module adopts full-speed single serial module of a XFI (10Gb serial interface) to replace the XENPAK and its derived products. Since the XFP module doesn't have serializer/ deserializer, XFP is smaller, cheaper than XENPAK. And its’ power consumption is also less than XENPAK.
