HPE J4859C Network Transceiver Module Networking

X121

The maximum speed with which data can be transmitted from one device to another.

This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced.

The greatest distance over which the data/signal can be transferred.

The distance over which a wave repeats itself. The wavelength determines the characteristics of the wave e.g. red light has a different wavelength to blue light.

A duplex communication system is a point-to-point system composed of two connected parties or devices that can communicate with one another in both directions, simultaneously.

A Medium Dependent Interface (MDI) describes the interface (both physical and electrical) in a computer network from a physical layer implementation to the physical medium used to carry the transmission. Ethernet over twisted pair also defines a medium dependent interface crossover (MDIX) interface. Auto-MDIX ports on newer network interfaces detect if the connection would require a crossover, and automatically chooses the MDI or MDIX configuration to properly match the other end of the link.

The number of sockets (ports) for fibers (cables).

Amount of power consumed by this model, often expressed in watts (W). Typical values that manufacturers give are power consumption when off, standby/suspended mode, typical use, maximum usage.

Weight of the product without packaging (net weight). If possible, the net weight is given including standard accessories and supplies. Please note that sometimes the manufacturer leaves out the weight of accessories and/or supplies.
