The classification of high-speed cable
1, 10 g SFP + SFP + DAC
10 g SFP + turn SFP + DAC is passive type biaxial cable components, and directly connected to the SFP + module, has a high density, low power, low cost, and the characteristics of low latency, has now become a mainstream interconnection of cloud computing and cloud storage tool.
2, 40 g turn QSFP QSFP + + DAC
40 g turn QSFP QSFP + + DAC offers a cost-effective way to build internal frame and cross frame QSFP + 40 g link between the switch port, the access layer upward to the core of the trunk link up to 40 g / 100 g, with its high speed, the characteristics of low latency is widely used in high speed backbone network, enterprise network exchange and storage.
turn 3, 40 g QSFP + 4 XSFP + DAC
turn QSFP + 4 XSFP QSFP + + at the end of the DAC is 40 g interface, accord with SFF - 8436 requirements, on the other side is 4 10 g SFP + interface, accord with SFF - 8432, by 12 core MPO high density optical cable connection among them, and then according to customer demand for both ends of cable length, branch, in the middle of the MPO cable join implementation, 40 g optical signal is divided into four road, 10 g signal conversion is the most economic and simple implementation switch port.
4, 40 g turn QSFP + 4 XFP DAC
turn 40 g QSFP + 4 XXFP + one end of the DAC is a 40 g QSFP + interface, the other end is four XFP 10 g interface. Due to no DAC copper standard XFP optical module, equipment transmission signal compensation is low, the loss of cable itself is very high, therefore can only make short distance transport, normally only done within 2 m distance, 40 g QSFP + interface to realize interconnection of XFP port.
5, 25 g SFP28 SFP28 DAC
25 g SFP28 turn SFP28 DAC can provide customers with 25 g high-bandwidth data connectivity, comply with the IEEE P802. 3 by Ethernet standard and SFF - 8402 SFP28, are widely used in the data center or super calculate system in the scene.
6, 100 g QSFP28 QSFP28 DAC
100 g QSFP28 turn QSFP28 DAC can provide customers with 100 g high-bandwidth data connectivity, providing duplex channel 4 road, per channel work rate can support to 25 gb/s, gathering bandwidth 100 gb/s, in line with the SFF - 8436 specification, used in QSFP28 port of the connection between the devices.
7, 100 g QSFP28 4 SFP28 DAC
100 g QSFP28 turned 4 SFP28 DAC is 100 g QSFP28 interface at one end, on the other side for the four 25 g SFP28 interface, can provide customers with 100 g high-bandwidth data connectivity, accord with SFF - 8665 /设定触发器, 8679年,IEEE 802。 3 bj and InfinibandEDR standard, widely used in the data center or super calculate system in the scene.
