Is the QSFP28 optical module a better solution for the 100G network?
Posted on May 24, 2017 by cozlink.com
100G network development direction is 10G → 40G → 100G, 100GBASE QSFP28 optical module appears, there are already some data centers have begun to use this method before the emergence of 100Gase QSFP28 optical module (one can support the 100G transmission of optical modules) to achieve the 10G upgrade to 100G. So, the question came, why would there be the 100GBASE QSFP28 light module? Does the QSFP28 optical module completely replace other 100G optical modules? How will the QSFP28 optical module change the data center? After reading this article, I think you will find the answer.Advantages of QSFP28 optical modulesThe cost and power consumption of the data center is one of the important factors that its builders need to consider, which is also an important driving force for the development of optical communication market. Looking back on the development of the 100G optical module, the development and improvement of its packaging style (CFP, CFP2, CFP4) and standards are mainly focused o..
CWDM technology utilizes optical division multiplexer to multiplex optical signals with different wavelengths to single fiber for transmission. In the receiving terminal of the link, through optical division demultiplexer, composite signals in the fiber are demultiplexed to the signals with different wavelengths connected with corresponding receivers. CWDM is in low cost, low power consumption, small volume and other advantages. Due to Its emergence, carrier operators found a transmission resolution plan with low price and high performance, which has greatly improved fiber availability and brought about great convenience for carrier operators and users.Basic Structure of 100G CWDM NetworkBasic structure of 100G CWDM network: 10G CWDM SFP & light module & LC optical patch & CWDM multiplexer/demultiplexer & fiber & CWDM multiplexer/demultiplexer & LC optical patch & 10G CWDM SFP & light module. These parts can increase the capacity of data transmission. Th..
Network Splitter (TAP) - a real helper for real-time monitoring of the network
Posted on Jul 10, 2017 by cozlink.com
In the increasingly developed network today, the network data monitoring has become an important means for enterprise users to solve network problems, to protect the network security. The Network Splitter (TAP) is one of the most popular methods of acquiring network data in real time. This tutorial will cover it in detail.Network Splitter (TAP) basicsThe Network Splitter (TAP) is a device that replicates Ethernet traffic, enabling real-time access to network traffic without interrupting normal network traffic. In use, the network splitter (TAP) should be connected in advance to the monitored link, where the network splitter (TAP) copies the network data in the monitored link to its other or more Port for different analysis tools for analysis.The type of network splitter (TAP)There are two main types of network splitter (TAP): active network splitter (TAP) and passive network splitter (TAP), passive network splitter (TAP) does not need electricity to run, the source network splitter (TA..
