Transceiver CBO JL485A-BO SFP28 25Gbps glasvezelmodule

The CBO JL485A-BO SFP28 25Gbps fiber optic module is a compact pluggable transceiver engineered for 25 Gigabit Ethernet links. Designed for use with compatible HPE Aruba and other 25Gbps-ready switches and network devices, this BlueOptics module offers a small form-factor interface for high-speed uplinks, server connections and aggregation ports. The transceiver supports single-mode or multimode fiber as specified by the network design and provides a low-latency physical link for data center and enterprise environments where consistent 25Gbps throughput is required.

Advantages

The module delivers 25Gbps line rate in an SFP28 form factor, enabling higher port density compared with larger interfaces. Its plug-and-play design simplifies installation into SFP28-capable ports and reduces downtime during upgrades. The compact size and standardized connector ensure compatibility with common fiber patching practices and fiber cabling infrastructure. Built to provide stable optical performance, the transceiver supports long continuous operation in rack-mounted and blade environments.

Suitable for

• High-speed uplinks between switches and aggregation layers
• Server-to-switch connections in data centers
• Inter-rack fiber links and campus backbone segments
• Network upgrades from 10Gbps to 25Gbps

Key specifications

• Form factor: SFP28 small form-factor pluggable
• Data rate: 25 Gbps
• Medium: fiber optic (single-mode or multimode depending on variant)
• Connector type: standard LC duplex (typical for SFP28 fiber modules)
• Typical use: short to long reach fiber links based on transceiver variant
• Compatibility: designed for use with HPE Aruba and other compatible 25Gbps-capable network devices

How to use

Before installation, verify that the target switch or network device supports SFP28 modules and that the fiber type and wavelength match your link requirements. Insert the transceiver into an SFP28 port until it latches, and connect LC-terminated fiber patch cords to the module. Ensure transmit and receive pairs are correctly oriented. After physical installation, confirm link status and negotiate speed and duplex settings via the device management interface. For multi-vendor environments, check device compatibility lists or test modules in a non-critical segment before widespread deployment.

Recommendations

Handle the module by the edges and avoid touching the optical interface. Keep dust caps on when the transceiver is not in use and clean fiber connectors with recommended cleaning tools before mating. Maintain proper bend radius for fiber cabling and monitor link performance after installation to ensure stable 25Gbps operation.
