A transceiver that unlocks 100 Gigabit Ethernet speeds over multi-mode fiber, boosting bandwidth and future-proofing MMF networks.

10x faster than traditional MMF, improved scalability, longer reach (up to 100 meters), and cost-effective compared to single-mode fiber upgrades.

It typically employs PAM-4 (Pulse Amplitude Modulation with 4 levels) on each of its 10 parallel lanes, achieving the 100GbE data rate over MMF.

While OM4 MMF is sufficient for typical 100GbE distances, OM5 MMF with its lower attenuation is recommended for maximizing reach and achieving longer distances up to 100 meters.

The parallel lane architecture inherently mitigates the impact of modal dispersion compared to single-lane solutions. Additionally, advanced equalization techniques within the transceiver further compensate for modal effects.

CFP2 transceivers offer detailed real-time data on parameters like laser temperature, optical power levels, and voltage, enabling proactive maintenance and troubleshooting.

Advanced link loss detection and recovery protocols ensure fast and seamless failover to redundant links in case of connection interruption, minimizing downtime.

Ensuring compatibility between equipment, migrating older MMF infrastructure if needed, and managing the increased power consumption effectively.

Green is on the agenda! Expect energy-efficient designs, renewable energy integration, and smart power management features to minimize CFP2's environmental footprint.

While single-mode parallel solutions offer even higher potential speeds, they require expensive mode-conditioning equipment and specialized MMF. CFP2 provides a practical and cost-effective alternative for many high-bandwidth MMF applications.

Most major network management platforms provide integration with CFP2-based switches, allowing for centralized monitoring, configuration, and performance optimization.

High-speed links present a larger attack surface. However, features like secure boot, hardware encryption, and secure firmware updates can mitigate these risks.
