CBO AOC SFP28 BlueOptics BO272703Q2M 2 m active optical cable compatible with Zyxel

The CBO AOC SFP28 BlueOptics BO272703Q2M is a 2 m active optical cable designed for SFP28 ports and compatible with Zyxel equipment. It delivers 25 Gbps full-duplex connectivity over a short reach using an optical link in a compact direct-attach form factor. The cable is intended for high-density networking environments where low latency, low power consumption and immunity to electromagnetic interference are required, such as server-to-switch and switch-to-switch links in data centers and rack interconnects.

Advantages

This active optical cable provides a stable 25 Gbps link while reducing electrical signaling issues and crosstalk common in copper twinax alternatives. Its optical transmission reduces susceptibility to electromagnetic interference and allows for consistent performance in congested cabling environments. The compact SFP28 form factor supports high-density port deployments and helps conserve rack space. The 2 m length is suitable for short-reach connections inside racks or between adjacent racks, offering a balance between reach and low insertion loss.

Suitable for

• Server-to-switch connections in data centers
• Switch-to-switch links for top-of-rack and leaf-spine architectures
• High-density rack interconnects where SFP28 ports are available
• Environments requiring reduced electromagnetic interference and low latency

Key specifications

• Connector type: SFP28 direct-attach active optical cable
• Data rate: 25 Gbps (per full-duplex link)
• Length: 2 meters
• Transmission medium: single-mode/multimode optical fiber within AOC assembly
• Form factor: compact SFP28 compliant direct-attach
• Power consumption: low-power optical transceiver modules integrated in the AOC
• Compatibility: designed for equipment compatible with Zyxel SFP28 ports

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your devices until it latches. Ensure that both devices support 25 Gbps operation and have compatible SFP28 port firmware or compatibility settings enabled. Route the 2 m cable to avoid sharp bends and maintain the manufacturers' recommended minimum bend radius. After physical installation, verify link status on both devices and confirm negotiated speed and link integrity through the network management interface.

Recommendations

Use the cable for short-reach optical connections inside racks or between adjacent racks. Avoid tight bends, excessive stress on the connectors and exposure to mechanical damage. Confirm device compatibility with Zyxel SFP28 ports before deployment and test link performance under expected traffic conditions.
