operation, easy maintenance and management, convenient upgrade and low cost.
The E-pon system is composed of Olt (optical circuit terminal-optical line termination), ONU (Optical Network Unit-optical Network) and fiber wiring unit, and the system uses Ethernet protocol. We call the downlink signal from Olt through 1:n optical passive splitter to ONU, from ONU to Olt for uplink signals. The data of the E-pon system is transmitted through an indefinit
of optical line terminals (OLT), Optical Network Unit (ONU)/Optical Network terminal (ONT) and optical distribution network (ODN), the so-called "passive", refers to all ODN by passive optical splitter and optical fiber and other passive optical components, excluding any active nodes. The PON technology uses a point to a multi point topology, and the downlink light signal emitted by Olt is broadcast through a passive optical
First look at two pictures:
1. The first time you open the Reference dialog (Reference Manager), name is not fully displayed:
(Figure 1)
2. Then double-click or drag splitter to have the name display full:
(Figure 2)
3. The next time you open the Reference dialog, and then back to Figure 1, then you have to double-click or drag splitter ... Every time you open a reference dialog box, you have to to

After you successfully register the window class, you can create a separator bar. Here's my sample interface, which consists of a tree view, a s

The telephone LINE is derived from the PHONE port of the splitter. The ADSL telephone interface is connected to the MODEM port of the splitter. Connect the crystal head at one end of the network cable to the LANRJ45 interface

He wrote the first version of the word segmentation algorithm. He was asked to rewrite it when he showed it to the boss.
The reasons are as follows:
1. How to test and test data?
2. Does splitter do too many things?
3. What should I do if there are repeated phrases like XXL dress?
Shuai started restructuring with these problems.
First of all, he discovered this, the judgment of C
to build multi-format supported media playing programs on the Windows platform. In addition, it is also very important to build a playback program for a custom format with MPC.
In addition to the player main program, the MPC project also contains many open-source filters, especially splitter filters, such as MP3, MPEG, MP4, mov, FLV, and real splitter. The project that uses MPC has many functions and perfe
Next we will introduce your usage one by one.Cy: Carry flag.The splitter in 8051 is an 8-bit splitter. We know that the 8-bit splitter can only be expressed as 0-255. If an addition is made, the sum of the two numbers may exceed 255, in this way, the highest bit will be lost, causing an operation error. What should I do? The highest bit is here. So it wi

, just like in the past construction, the waterproof and protection levels are IP50 and IP67 respectively. Finally, the advantages of the pre-connection mode are also reflected in the improvement and upgrade of the network. As described above, the rapid development of network applications will inevitably lead to changes and fixes of the network, however, due to the features of the connection method used in the past, in many cases, the customer may leave the case because the project is too comple

The single document interface has only one document class, but there can be more view classes. At least one view class is active. You can use GetActiveView () to get its pointer. No view class associated with document class has a control ID, which is an integer. If only one view class is displayed in total, the control ID of this class is AFX_ID

The Linux slab splitter uses this idea and other ideas to build a memory distributor with high efficiency in space and time.

When setting up a home wireless LAN, we use a wireless router to connect to the wired ADSL for network construction. Therefore, the configuration of the ADSL and the wireless router is cumbersome, so the emergence of broadband wireless cats simplifies some of the configuration problems. Now let's take a look at the configuration problems of broadband wireless cats at the ADSL end.
ADSL Broadband Wireless cat Configuration
A Broadband Wireless cat is actually a device that combines adsl modem wit
centered around the radiation, forming a star shape. The star structure is generally used for optical cable access networks of small and medium-sized CATV systems or municipal-County man networks.
The star structure has the advantages of one-time Optical Distribution, less Optical splitter, less optical fiber connection points, and less full optical path loss. In this way, the farther distance can be transmitted when an optical transmitter with the s
cables are well resolved. If the network terminal moves or the path is changed, then, the customer only needs to select the appropriate time to unplug the pre-connected optical fiber cable from the rack, and then re-pin the optical fiber splitter to the rack in the new location. The whole process takes only several minutes.
Based on the above analysis, we have summarized several features of pre-connection Optical Fiber Application:
