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 […]
