CBO 3m SFF-8644 to SFF-8644 Cable BlueOptics 2202508-4-BL, Male–Male

CBO BlueOptics 2202508-4-BL is a 3 metre SFF-8644 to SFF-8644 copper/active cable designed for short-reach, high-speed connections between compatible storage and networking equipment. The cable features SFF-8644 male connectors on both ends and provides a compact physical link for host-to-device or device-to-device connectivity in data centres, server racks and SAN environments. Its 3 m length balances reach and cable management, delivering low latency and a stable electrical interface for high-throughput applications.

Advantages

The cable offers a simple, direct connection without transceivers, reducing component count and simplifying deployment. Its active copper design supports reliable signal integrity over short distances while keeping power consumption and heat generation low compared with optical alternatives. The SFF-8644 connector pair provides a standardized interface for many modern storage and networking controllers, enabling straightforward integration into existing rack layouts and reducing cable bulk thanks to a slim cable profile and secure latch mechanism.

Suitable for

• Direct connection between servers and storage arrays in SAN and NAS installations
• Short-reach interconnects inside data centre racks and between adjacent racks
• High-throughput, low-latency links for RAID controllers and HBAs
• Temporary or permanent links for testing, provisioning and equipment replacement

Key specifications

• Connector type: SFF-8644 male to SFF-8644 male
• Length: 3 metres
• Cable type: copper / active copper assembly
• Intended reach: short-reach (data centre / rack-level)
• Use case: host-to-device and device-to-device interconnects
• Physical characteristics: slim-profile cable with secure latch connectors

How to use

Install the cable by inserting each SFF-8644 male connector into the corresponding SFF-8644 port on your server, storage array or switch until the latch clicks into place. Ensure both devices are powered down or follow hot-swap procedures recommended by the equipment vendor before connecting or disconnecting. Route the cable to avoid sharp bends and excessive tension; maintain the minimum bend radius specified by your rack management guidelines. After connection, verify link status through device LEDs or management interfaces and check for expected throughput and latency.

Usage recommendations

Use this active copper SFF-8644 cable for short-distance, high-bandwidth connections inside racks or between adjacent racks. Avoid exposure to extreme temperatures, liquids and mechanical strain. For longer distances or where optical isolation is preferred, consider optical transceiver and fiber options compatible with your equipment.
