FTTX FTTB QSFP+ Direct Attach Cable 40 Gigabit Passive Twinax Dac Cable


QSFP+ connectors provide four channels of data in one pluggable interface. Each channel is capable of transferring data at 10Gbps and supports a total of aggregate 40Gbps as specified for QSFP+. These interconnects have three times the density of SFP+ interconnects (MSA) and have been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.

QSFP+ cable assemblies are hot swappable and the programmed EEPROM signature enables the host to differentiate between a copper cable assembly and a fiber optic module.

Low power consumption assists in making the passive copper cable assembly an economic solution for withinrack, or rack-to-rack applications.
