Mellanox QSFP28 to SFP28 Adapter

$116.95 Regular price

Mellanox's QSFP28 to SFP28 adapter (QSA28) enables smooth, cost effective connections between a single lane transceiver/cable and a quad-lane port. The QSA28 provides the option to connect an SFP28 transceiver or cable to a QSFP28 port of an Nx100 Gb/s switch or network card. For example an SFP28-based cable can be connected to Mellanox's 100GbE ConnectX-4 adapter and to the 32x100GbE SN2700 Ethernet switch.

The QSA28 conforms to SFF-8402 for the SFP28 side and to SFF-8665 for QSFP28 standards and is thoroughly tested to meet strict quality requirements. The adapter has a QSFP28 form factor with a receptacle for an SFP28 transceiver/AOC/DAC connector. The QSA28 provides a solution for integrating systems using different vendors' equipment, is vendor agnostic and provides a direct path to the SFP unit's memory. The QSA28 interoperates with all major optical modules and direct attached copper cable vendors.

Its design assures minimum loss on the conversion path between the QSFP28 cage and the SFP28 receptacle. The RF (high speed data) channel of the SFP28 receptacle is connected to lane 1 of the QSFP28 connector. The three remaining RF channels on the QSFP28 connector are not connected. The QSA28 is qualified for 10GbE SFP+ and 1GbE SFP transceivers meeting the Small Form Factor Pluggable (SFP) Transceiver Multi-source Agreement (MSA).The QSA28 is a Mellanox registered US patent 7-934-959
