## Summary description

The BlueOptics ET7302-DAC-5M-BL is a 5-meter InfiniBand fibre optic cable featuring SFP28 connectors. It is designed for high-speed data transmission and offers reliable performance for data centers and networking applications. The male-to-male configuration ensures compatibility with various devices, making it an ideal choice for connecting switches and servers.

## Long description

The BlueOptics ET7302-DAC-5M-BL InfiniBand Fibre Optic Cable SFP28 5m Male Male is a 5-metre direct attach cable designed for short-range high-speed data links between networking devices. Built to support 25G connectivity over a twinax passive copper connection with SFP28 to SFP28 interfaces, this cable is intended for rack-to-rack and intra-rack links in data center and enterprise network environments. The design follows Multi-Source Agreement (MSA) standards to ensure mechanical and electrical compatibility with devices that accept SFP28 passive DACs.
Advantages
This 5 m passive twinax cable provides low-latency, low-power direct connectivity without active transceivers, reducing both power consumption and complexity. The SFP28-to-SFP28 male connectors enable straightforward plug-and-play installation in compatible ports. Manufactured using high-quality cable conductors and components, the product is suitable for continuous use in high-availability environments and is engineered for durability and long service life.
Suitable for
 Direct connections between switches and top-of-rack or adjacent-rack servers
 Short-distance InfiniBand, Ethernet or FCoE links up to 25 Gbps
 High-density data center environments requiring cost-effective copper DACs
Key specifications
 Length: 5 metres
 Connector type: SFP28 male to SFP28 male
 Data rate support: up to 25 Gbps
 Cable type: passive twinax copper (DAC)
 Wire gauge: 30 AWG
 MSA compliant mechanical and electrical form factor
 Typical use: intra-rack and adjacent-rack connections
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the two devices to be linked, ensuring the latches fully engage. Verify that both devices support passive 25G DACs and that firmware or software settings permit passive cable operation. After physical installation, check link status via the device management interface and confirm negotiated speed and link integrity. For safe handling, avoid sharp bends and do not place heavy objects on the cable to preserve signal integrity.
Usage recommendations
Use this cable for short-range links inside racks or between adjacent racks where a cost-efficient, low-latency 25G connection is required. Confirm device compatibility with SFP28 passive DACs before installation and avoid routing the cable near strong electromagnetic interference sources. For installations requiring longer distances or optical isolation, consider using optical transceivers and fibre cable alternatives.
