optical module Mainly includes Optical electronic devices, functional circuits and optical interfaces, etc., is an important device in optical communication Now let fast fiber optics (feisu.com) I. Look at the demandIt's good to see. whether the requirements are met , such as clothes have many styles, light modules also have many kinds of, mainly divided into: GBIC, SFP, SFP +, XFP, SFF, CF

MPO/MTP high-density optical fiber pre-connection system is mainly used in three fields: application of high-density environment in data centers, application of optical fiber to building, application of optical fiber to optical splitter, 40G, 100g sfp, connection applications of SFP + and other optical transceiver devices. This article focuses on why MPO/MTP high-density optical fiber pre-connection system

interface. What can I do? Because a Cisco TFTP Server upgrade requires that the Cisco switch fail to be connected to a PC with a TFTP Server installed on the network. After some look, finally found that the super engine 720 above a RJ-45 look like the interface, next to the words Link, play! The result is a try with the network cable, and the indicator light is not on. I thought that I had a hope and fell into the bottom, but I cannot give up. This interface is the only hope. Otherwise, I woul

, play! The result is a try with the network cable, and the indicator light is not on. I thought that I had a hope and fell into the bottom, but I cannot give up. This interface is the only hope. Otherwise, I would be discouraged from using xmodem to transmit 41 MB of IOS. Because I used xmodem to transmit a cisco Switch Failure IOS, it would take more than two megabytes. It took two hours. 41 MB? It can take up to 30 hours! So I started surfing the Internet to find information ......, Finally f

Multipath implements LUN device name persistence. I. Additional knowledge based on different transmission protocols, the network card can be divided into three types: an Ethernet card, an FC network card, and an iSCSI network card. (1) Ethernet Adapter: an Ethernet Adapter. The transmission protocol is an IP protocol. It is generally connected to an Ethernet switch through an optical fiber cable or twisted pair. Interfaces can be divided into optical ports and electrical ports. Optical interface

Today in the Webmaster station to see a netizen to write the photo album program, the function is quite simple, see he used the aspjpeg to generate thumbnails, not to recall using aspupload upload, so spent one hours to perfect his code. The following code has a simple comment, if you do not understand, please look at AspJpeg and AspUpload documentation (E, hope to have psychological preparation), can not understand the ask me. Here's the code: Copy Code code as follows: If sessio

database maintenance personnel of this system, this situation has appeared many times, even if the database is restarted, after a day or two, such a failure will also occur. At the same time, the system has not made any major changes recently.After receiving the fault report, the author can connect to the database database by SSH is very slow, it takes almost 1 minutes to connect. A simple look at the performance of the server, the development of IO very low, memory surplus is more, at least mo

default resource manager used by Windows but both Windo WS 2003 and Windows separate installable option called the Windows System Resource Manager (WSRM) s greater control over the CPU and Memory available to a process.First of all, lets look at the what we ' re trying to solve. Here we had a low-memory server (only 2Gb) running MongoDB on Windows R2 x64. There is a few databases of a few Gb each so the mongod.exe process quickly starts consuming as much memory as it can (RI ghtly so) to keep a

FTTD (Fiber to the Desk) cabling scheme is attributed to the overall FTTx system, FTTD as a high-level solution for cabling systems, the industry is well aware of the excellent transmission performance of fiber as a transmission medium, but also due to the high price of optical fiber active equipment, Led to few projects in the past few years large-scale use of FTTD wiring. In the rapid development of FTTX access network today, especially the development of FTTH networks, due to the overall indu
