configuration and wiring approach look the same. The color coding of the TPU2 line helps to compare these photos. Three Google TPU2 cabinets Google shows the top view of the TPU2 circuit board and the proximity of the front panel interface of the circuit board. All 4 quadrants of the TPU2 circuit board share the same power distribution system. We believe that the 4 TPU2 circuit board quadrants also share the same network connection through a simple network switch. It seems that each circuit boa

Light Cat is "optical modem", refers to the optical Ethernet signal into other protocol signal transceiver equipment, but also plays the role of modulation and demodulation. The optical cat is also known as a single port optical transceiver, which acts as a relay transmission device for the local network, and is suitable for the optical terminal transmission equipment of the base station as well as the leas

data, the MAC protocol can determine whether data can be sent in advance. If data can be sent, it adds some control information to the data, and finally sends the data and control information to the physical layer in the specified format; when receiving data, the MAC protocol first checks the input information and determines whether a transmission error has occurred. If there is no error, the control information is removed and sent to the LLC layer. Ethernet MAC is defined by IEEE-802.3 Etherne

situation of Internet cafes users, the main link is worth the Internet Café users reference, we recommend the first way. The first is the use of optical fiber transceiver to achieve the connection between the fiber and the dual-Wan port router, this way the biggest feature is the low input cost, but also the most suitable for Internet users a way. In the choice of fiber transceiver, the performance is of

wire breaker instead, after all, no-blade wire breaker generally uses a hexagonal design, which can effectively prevent minor cables from being damaged when it is used for wire stripping. On the contrary, when using a blade wire breaker to create a network cable, the sharp blade will cut the skin of the cable accidentally, which brings a fault risk to the efficient communication of the network in the future. Optical module, reasonable connectionThe so-called optical terminal module is the conne

Port The AuI port is the interface used to connect to the coarse coaxial cable. It is a "d" Type 15-pin interface, this is one of the most common ports in the ring or bus network. The router can connect to the 10base-5 network through a coarse coaxial cable transceiver. But more is the use of external transceiver (AUI-to-RJ-45), to achieve the connection with the 10base-t Ethernet. Of course, you can also

used normally, the general router has a control port "console ", it is used to connect to a computer or terminal device and configure a router through specific software. Next, let's take a look at the router's LAN and WAN connection ports. 1. LAN interface According to the interface name, we can see that these interfaces are mainly used to connect routers and LAN, because the LAN type is also diverse, therefore, the LAN interface type of the router may be diverse. Different networks have di

Next, I will explain the implementation of the SATA host protocol's physical layer. Is the physical layer structure given in the standard SATA protocol document. It contains the control module, clock data extraction unit, synchronous character source and synchronous character detection module, and analog front-end. The control module coordinates and controls the Logic Functions of the entire physical layer, and provides control signals and status information interfaces to the upstream protocols.

1. Do you see the light on the optical transceiver or optical module and the twisted pair port led? A, such as the transceiver of the optical port (FX) LED is not lit, please determine if the fiber link is cross link? The fiber jumper is connected in a parallel way and the other end is connected in a cross way. b, such as a transceiver of the light port (FX)

connect to the coarse coaxial cable. It is a "d" Type 15-pin interface, this is one of the most common ports in the ring or bus network. Vro accessibleThe coarse coaxial cable transceiver is connected to the 10base-5 network. However, it is more with the help of external transceiver (AUI-to-RJ-45), to achieve Network connection. Of course, you can also use other types of

meet high-speed bandwidth needs, such as 10 GB Ethernet and 16 GB optical fiber channels. The industry is upgrading the OM3 and OM4 light green optical fiber cables to 50 micron for long-distance connections. OM4 is ideal for horizontal cabling and inter-IDC cabling, whether for Ethernet or fiber channel. "If you are using multimode optical fiber, you should purchase OM4," Martin said. "The reason why OM4 is recommended is that it can be used for both 40g and G Ethernet, but also for high-spe

Twisted Pair wires have two connection standards: EIA/TIA 568B standard and EIA/TIA 568A standard.

Crossover line: One end is connected in T568A line Order and the other end is connected in T568B line order. Connection Met

no longer possible to inherit from another base class. Therefore, it is a good idea to provide an abstract interface (interface), a class can implement multiple interfaces, thus simulating the implementation of "multi-Inheritance", for the design of the class provides greater flexibility. Minimizing the direct access to variables the encapsulation principle of data should be normalized, not exposing the properties of one class to other classes, but should protect them by means of access, which

transceiver circuit energy consumption management Although the power management of embedded processors has been thoroughly studied, the energy-saving design of Wireless Transceiver systems is not enough. Wireless Communication accounts for the majority of the energy consumption of the entire wireless sensor network, so it is very important to manage the energy consumption of the Wireless

The Data encapsulation principle should be standardized. Instead of exposing the attributes of a class to other classes, we should protect them through access methods, which is conducive to avoiding the ripple effect. If the name of an attribute changes, you only need to modify its access method, rather than modifying all relevant code. Back to Top Subclass features to complete speci

(1). AuI PortThe AuI port is the interface used to connect to the coarse coaxial cable. It is a "d" Type 15-pin interface, this is one of the most common ports in the ring or bus network. The router can connect to the 10base-5 network through a coarse coaxial cable

There are many different classifications of fiber optic transceivers, and most of the attention is being paid to categories that are differentiated by fiber connectors: SC connectors, fiber transceivers, and fc/st connectors. When using a fiber-optic transceiver to connect to different devices, you must be careful to use different ports. 1, optical transceiver to the 100BASE-TX device (switch, hub) conn
