40G Transceivers With MTP/MPO Interface vs. 40G Transceivers With LC Interface
With 40 Gigabit Ethernet commonly deployed in most data centers, it is very essential for the data center managers to employ the suitable 40G devices like 40G QSFP+ transceivers. Nowadays, various 40G transceivers are available on the market, but mainly there are two interfaces adopted by 40G QSFP+ transceivers—MTP/MPO and LC. What’s the difference between […]
40G QSFP BiDi Transceiver – Cost-effective Solution for Migration From 10G to 40G
With the data center consolidation, server virtualization, and new applications requiring higher data transport rates, the data center network is shifting to 10 Gbps at the access layer and 40 Gbps at the aggregation layer. In order to support 40-Gbps connectivity, data center architects are challenged by the need for a major upgrade of the […]
Why Does AOC Meet With Great Favor in 40G Network?
Nowadays more and more data centers are deploying 40G Ethernet links due to the growing need for higher network bandwidth. A variety of technologies and solutions can be chosen for 40G transmission, which includes 40G QSFP+ transceivers, 40G direct attach cables (DACs) and 40G active optical cables (AOCs). All of the three are used to […]
Instructions for 40G QSFP+ Transceiver Installation and Removing
As is know to all, 40G QSFP+ transceiver modules are hot-swappable, parallel fiber-optical modules with four independent transmit and receive channels. These channels can terminate in another 40G QSFP+ transceiver, or the channels can be broken out to four separate 10G SFP+ transceivers. QSFP+ transceiver modules connect the electrical circuitry of the system with either […]
Why Are 40G Active Optical Cables Popular?
40 Gigabit Ethernet is the trend of higher data transmission. Thus, 40G optical devices are gaining popularity, including 40G QSFP+ transceivers and 40G direct attach cables. 40G direct attach cable (DAC) provides a cost-effective solution for high-density network connectivity. It is a kind of high-speed cable which has transceivers on either end used to connect […]
