QSFP-4X10G-ACxM-GT
40GBASE-CR4 QSFP+ to 4x10GBASE-CU SFP+ Active Cable Cisco Compatible- xM
The Gigatech products QSFP-4X10G-ACxM is programmed to be fully compatible and functional with all
intended Cisco switching devices. This direct attach copper cables support 4 lanes of 10Gbs (40Gbs
composite). The active transmitter can be configured to compensate for different cable lengths. The
active QSFP+ to 4 SFP+ cable is a low cost alternative for short reach application.

Block Diagram of Transceiver
The transmitter side accepts electrical input signals. All input data signals are differential LVPECL or CML
logic and they are internally terminated. The parallel input electrical signal first is processed via the PreEmphasis.
At the receiver side, the parallel electrical signals are recovered via Equalizer. The output electrical
signals of the receive side are voltage compatible with Current Mode Logic (CML) levels. All data signals
are differential and support a data rate up to 10Gbps per channel.
All transmitter signals and receiver signals are AC coupled internally on both module ends.
Active cable assembly has built in MCU, offer a number of additional host-management capabilities. I2C
(inter-IC bus protocol) interface and on-board EEPROM features enable the host to detect or configure
specific performance characteristics.
