Elink's LNK-DP3CXX-XXX High Speed 40G QSFP+ to 10G SFP+ Direct Attach Cable copper cable assemblies offer an economical alternative for short reach 4X applications.
The QSFP+ connectivity component meets the parameters delineated by the QSFP Multi-Source Agreement in terms of form factor, optical/electrical connections, and design. It offers 4 serial channels running at 10Gbps each, representing a total aggregate 40Gbps, in a single pluggable interface, and all that 3 times denser than SFP+ interconnects.
Moreover, they are programmed using EEPROM signature to differentiate between copper and fiber optic cables, while the hot swappable feature renders them ideal for rack-to-rack and withinrack deployment. Not to mention, their low power disbursement keeps energy costs to a minimum.
The Hybrid cable is compliant to the Small Form Factor SFF-8436 and SFF-8431, enabling multi-gigabit data rates ranging from 1 Gb/s to 10 Gb/s per channel, and an aggregate data rate of up to 40 Gb/s (4 x 10Gb/s). It can provide transmission up to 5m in length (under the passive limiting situation). The connectors used are the high-density QSFP 38-PIN and SFP 20-PIN.
These values represent the damage threshold of the module. Stress in excess of any of the individual Absolute Maximum Ratings can cause immediate catastrophic damage to the module even if all other parameters are within Recommended Operating Conditions.
