Direct Attach Cable SFP28 to SFP28 BlueOptics MCP2M00-A002E26N-BL, 25GBASE-CR, 2 m, AWG30

BlueOptics MCP2M00-A002E26N-BL is a passive SFP28-to-SFP28 direct attach copper (DAC) cable designed for 25GBASE-CR links. The 2 m AWG30 twinax assembly provides a low-latency, short-reach electrical connection between SFP28 ports on switches, network interface cards and servers. This fixed-length copper solution supports 25 Gbit/s per lane signalling and is intended for high-density top-of-rack and adjacent-rack connections in data center environments.

Advantages

The cable offers a compact twinax design with low insertion loss and predictable performance at 25 Gbit/s, enabling reliable short-reach links without the need for transceivers. Its passive construction limits power consumption and reduces component count in rack deployments. The 2 m length balances reach and cable management for common rack and cabinet layouts while the AWG30 conductors maintain signal integrity for the specified distance.

Suitable for

• Top-of-rack connections between switches and leaf switches
• Switch-to-switch links within the same rack or adjacent racks
• Direct server-to-switch or server-to-NIC connections requiring 25 Gbit/s
• High-density data center installations with constrained power budgets

Key specifications

• Connector type: SFP28 (both ends)
• Data rate: 25 Gbit/s per lane
• Media: Twinax copper (passive)
• Length: 2 m
• Conductor size: AWG30
• Use case: Short-reach electrical links (25GBASE-CR)

How to use

Insert each SFP28 connector into compatible SFP28 ports on network equipment until the latch engages. Verify that the host devices recognise the direct attach cable and that link indicators show an active 25 Gbit/s connection. Route the cable to avoid sharp bends and maintain recommended bend radii; secure as needed within the rack to prevent strain on connectors. No additional power or optical transceivers are required for operation.

Usage recommendations

Install the cable in environments that match the specified short-reach application: do not exceed the 2 m length for guaranteed performance. Avoid repeated hot-plug cycles to reduce mechanical wear, and maintain proper airflow and cable management in densely populated racks. Check compatibility lists of switches and NICs if vendor interoperability information is required.
