The HPE FTLF8536P4PCL-HP module is specifically designed for short-range multimode fiber connections, supporting high-speed data transmission within racks, across rows, and between aggregation layers in enterprise and cloud data centers.

SFP28 Form Factor Advantages

The SFP28 form factor maintains physical compatibility with SFP+ ports while enabling higher throughput. This compact and hot-pluggable design simplifies installation and maintenance without requiring extensive infrastructure modifications. Network administrators can upgrade to 25GbE performance while preserving existing rack density and switch port configurations.

High Port Density and Scalability

With its small footprint, the SFP28 optical module enables greater port density on switches and network interface cards. This allows organizations to scale horizontally without increasing physical rack space. High-density deployments reduce overall infrastructure costs and improve airflow management within data center racks.

Energy Efficiency Optimization

Compared to deploying multiple 10GbE links, a single 25GbE SFP28 module reduces power consumption per gigabit of throughput. This improved energy profile supports sustainable IT initiatives and lowers operational expenditure, particularly in large-scale cloud and enterprise facilities.

Short Wave Multimode Fiber Performance

The HPE FTLF8536P4PCL-HP operates using short wave laser technology optimized for multimode fiber applications. It supports transmission over OM3 and OM4 fiber cables, making it ideal for short-distance interconnections such as top-of-rack to aggregation switch links.

Transmission Distance Capabilities

When deployed with OM3 multimode fiber, this optical transceiver typically supports distances up to 70 meters. With OM4 multimode fiber, it can extend connectivity up to 100 meters. These ranges are sufficient for most intra-data center connections and structured cabling environments.

Low Latency Data Transmission
