Product Description:
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.
Features:
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.
Technical Parameters:
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.
