Description

The MAM1Q00A-QSA28-BCC is a Blue Cable Co QSFP28 to SFP28 adapter, compatible with NVIDIA Mellanox platforms. It enables an SFP28, SFP+, or SFP transceiver to be installed directly into a QSFP28 port, providing a cost-effective solution for connecting 25GbE, 10GbE, or 1GbE SFP-form-factor equipment to switches and NICs with QSFP28 ports. The adapter uses lane 1 of the QSFP28 connector and is plug-and-play with all major SFP28 transceivers, AOC, and DAC cables. Backed by Blue Cable Co's 5-year advanced hardware replacement warranty.

  • Plug-and-play QSFP28 to SFP28 adapter — accepts SFP28, SFP+, or SFP transceivers, AOC, and DAC cables
  • Enables 25GbE SFP28, 10GbE SFP+, or 1GbE SFP connectivity on QSFP28 ports of Mellanox switches and NICs
  • Uses lane 1 of the QSFP28 connector — single lane, not a 4x25G breakout
  • SFF-8636 compliant I2C management interface — passes SFP transceiver identity to the host
  • Built-in EEPROM for product identification
  • Low insertion loss with matched impedance design
  • Secure latching mechanism for reliable retention in the QSFP28 cage
  • Compliant with QSFP28 MSA SFF-8665 and SFP28 MSA SFF-8402
  • Operating case temperature range: 0°C to +70°C
  • Maximum power consumption: 0.1W
  • RoHS compliant

FAQs

Q1: Which NVIDIA Mellanox platforms is the MAM1Q00A-QSA28-BCC compatible with?
A1: The MAM1Q00A-QSA28-BCC is compatible with NVIDIA Mellanox switches and NICs that have QSFP28 ports, allowing an SFP28, SFP+, or SFP transceiver to be installed in place of a QSFP28 module. It is designed as a compatible replacement for the OEM MAM1Q00A-QSA28. Contact our team to confirm fit for your specific platform before ordering.

Q2: What transceivers and cables can I plug into this adapter?
A2: The MAM1Q00A-QSA28-BCC accepts SFP28 transceivers (25GbE), SFP+ transceivers (10GbE), SFP transceivers (1GbE), SFP28 AOC, and SFP28 DAC cables that conform to the SFP MSA standard. It is vendor-agnostic and interoperates with all major optical module and direct attach copper cable vendors.

Q3: Does this adapter support 4x25G breakout — can I get four 25G ports from one QSFP28 port?
A3: No. The MAM1Q00A-QSA28-BCC uses only lane 1 of the QSFP28 connector, providing a single 25GbE, 10GbE, or 1GbE connection per QSFP28 port. For 4x25G breakout, a dedicated QSFP28 breakout cable or module is required.

Q4: How does the host identify the SFP28 transceiver inserted into this adapter?
A4: The adapter includes both a built-in EEPROM for its own product identification and an SFF-8636 compliant I2C management interface that provides a direct path to the inserted SFP transceiver's memory. The host system can read the transceiver's vendor information and diagnostic data as it would from a directly installed module.

Q5: Can this adapter connect a Mellanox 100GbE QSFP28 switch port to a 25GbE SFP28 server NIC?
A5: Yes, that is a primary use case. Install the MAM1Q00A-QSA28-BCC into the QSFP28 port of a Mellanox switch, then connect an SFP28 DAC cable or transceiver to the adapter's SFP28 receptacle for direct connectivity to a 25GbE SFP28 NIC port — without replacing either device.
