"Netizen asks a question": have been not clear exactly what difference does photoelectric converter, fiber transceiver, light cat, light module have? "Answer": Optical module is inserted in the router or switch, can not be used independently, belong to other devices part. and netizens mentioned (photoelectric converter, optical transceiver, light cat, optical module) A few things are basically one thing,

Absrtact: This paper introduces the technical requirements of E-PON (Ethernet passive optical network) system for ONU (Optical Network Unit) and the basic principle and design method of ONU transceiver module, and gives the experimental results. Keywords: e-pon;onu; burst; transceiver module; BiDi 1. Foreword With the rapid development of the information society, People's reliance on it becomes more and

1. Similarities 1.High-speed can transceiver, can reach 1 mbaud 2.Can all enter the standby mode 3.Both have strong anti-interference capabilities 4.Both features hot shutdown (overheating protection) 5.When txd (Pin 1) is high, the output bus is in the implicit (recessive) state. When txd is low, the output bus is in the dominant (dominant) state. 6.Differential voltage VI (DIF) = VCANH-VVANL, when vi (DIF)> 0.9v, the bus is dominant; VI (DIF) Ii. Di

Second, transceiver service detailed 1. Transceiver Service Analysis Summary Transceiver Service is the core of the transceiver system, transceiver kernel is responsible for reading the port, transceiver definition and parameter

In the wireless data transmission system, the wireless transceiver chip is the core carrier of the technology. As the signal sending and receiving, modulation, and debugging, it plays an absolute core role. We will compare and analyze several Wireless Transceiver Chip Solutions. 1) CC1000 Wireless Transceiver Chip Solution CC1000 is a single-chip programmable RF

Introduction In the domestic common information development and implementation projects, most of the work of the development of the workload is concentrated in order to adapt to different customer needs, the specific modules to modify, and ultimately achieve customer expectations of the software functional characteristics. But for the development of vendors, in the face of different customers to develop different software versions, will lead to duplication of labor, cost rise, maintenance incre

of the signal, keeping the low-frequency signal, to compensate the transmission line attenuation of the signal, improve the performance of the eye graph and guarantee the transmission quality.3 Xilinx FPGA Transceivers3.1 system ArchitectureThe 7 Series FPGAs GTX and GTH transceivers is power-efficient transceivers, supporting line rates from $ MB/s to 12.5 GB/s for GTX transceivers and 13.1 Gb/s for GTH transceivers. Four Gtxe2_channel Primitives and one Gtxe2_common primitive to be a Quad.The

1.UDP the difference between using the Connect function and not using the Connect function* No longer use sendto/recvfrom, but only write/read or SEND/RECV, which means that the destination IP cannot be specified when sending and receiving data* Asynchronous errors raised by connected UDP are returned to the process in which they are located, while non-connected UDP does not receive asynchronous errors* Connected UDP has high transceiver efficiency. B

Switch Transceiver Principle: Working at the data Link layer, the switch has a very high bandwidth of the back bus and the internal switching matrix. All ports on the switch are hooked up to this bus. When the packet is received, the processing port looks for the in-memory MAC address (that is , the physical address in the serial EEPROM that is cured on the NIC ) to that port, which is sent to the destination port through the internal exchange matrix.

grab the bag ...I turned on the main switch mirroring mode, grasping the main interface data, so as to ensure that all the user's data, so as to facilitate the analysis3, waited for about 3 hours, when I was ready to give up, suddenly the user again abnormal fall off the line ... At this time the clutch software is also jammed ....I know that at this time a large number of packet attacks caused the computer to be unable to respond ... So now I can only wait.4, probably waited for half an hour o

First, why use SerDes Traditional source synchronous transmission, clock and data separation. At low rate (When the rate gets higher, it's going to be a problem.Because the transmission line delay inconsistency and jitter exists, the receiver can not correctly sampled data, to the point of the forbidden Eye graph.Then I thought about recovering the clock from the data to sample the data, the CDRThus there is no delay inconsistency, and a slight jitter does not affect the sampling (the recovered

When using a fiber-optic transceiver, it is necessary to pay attention to some problems in order to make the use of fiber-optic transceiver better. 1. View whether full duplex or half-duplex is supported. Some of the market can only use a full dual public environment, can not support Half-duplex, such as receiving other brands of switches or hubs, and it uses Half-duplex mode, otherwise it will cau
