40G DAC or 40G AOC ? Which Is Your Option？
In recent decades, we are so astonished at the fast updating in telecommunication field that we worried whether we can keep pace with the speed of innovation such as the revolution of iphone series. In terms of Gigabit Ethernet, Direct Attach Cable (DAC) and optical transceivers are main media for switches connection in data transmission. With regard to 40G transmission devices, there are main three types: QSFP+ DAC cables, QSFP+ AOC cables and QSFP+ optical transceivers. QSFP+ DAC cable is used for short range transmission over copper cable while QSFP+ AOC cable used for longer transmission via fiber optic cable. Do they have more differences? And how should we select? In this passage, we will provide a satisfied solution to you. Overview on 40G QSFP+ DAC DAC assembly is a high performance integrated duplex data link for two-directional communication over optical or copper cable. There is a transceiver shaped device on DAC cable’s either end used to connect switches to routers...
