Product Overview

Migration Path

Smooth upgrade from 10G/25G to 50G using the same SFP form factor and existing fiber infrastructure.

SFP Form Factor

Compact SFP56 form factor fits existing SFP slots, maximizing port density per line card.

Multi-Rate

Support for 10G, 25G, and 50G speeds in a single module for flexible network deployment.

5G Fronthaul

Purpose-built for eCPRI and 5G fronthaul applications with precise timing support.

Backward Compatible

SFP56 ports accept SFP28 and SFP+ modules for mixed-speed deployment flexibility.

Low Power

Industry-leading power efficiency reduces operational costs in high-density access deployments.

Features and Benefits

The ideal step-up from 10G/25G access networks.

50G SFP56 transceivers deliver 5x the bandwidth of 10G in the same compact form factor, enabling cost-effective upgrades for service provider access and 5G fronthaul.

Multi-Rate Operation

Single module supports 10G, 25G, and 50G speeds for phased network migration.

5G Fronthaul

Supports eCPRI timing for 5G radio access network fronthaul connectivity.

PAM4 Signaling

50G PAM4 per lane doubles per-lane throughput over 25G NRZ signaling.

SFP Backward Compatibility

SFP56 ports natively accept SFP28 and SFP+ modules for flexible mixed-speed deployments.

Cisco Certified

Tested and validated on Cisco NCS, ASR, and Catalyst platforms with full TAC support.

Low Power

Under 1.5W typical power consumption for dense access deployments.
