Overview of 455886-B21 10GBASE-LR SFP+ Transceiver Module:

The HPE 455886-B21 is a high-performance 10GBASE-LR SFP+ optical transceiver designed for long-distance, high-bandwidth connectivity in data centers, enterprise networks, cloud platforms, and HPE BladeSystem deployments.

Engineered to meet SFP+ MSA, IEEE 802.3ae, and 10GbE Long-Reach (LR) standards, this module delivers reliable 10 Gbps links over single-mode fiber (SMF) with a reach of up to 10 kilometers.

It features a 1310 nm DFB laser, low power consumption, and full Digital Diagnostics Monitoring (DDM/DOM) for real-time optical parameter reporting.

The module supports hot-swap operation and integrates seamlessly with HPE switches, servers, and storage platforms that accept 10G SFP+ LR optics.

Key Features:

1. 10GbE Connectivity: Supports data rates up to 10.3125 Gbps.
2. Long-Range Capability: Transmits data up to 10 km on 9/125µm Single-Mode Fiber (SMF).
3. Hot-Swappable: Allows for installation without powering down the host device, minimizing downtime.
4. Digital Optical Monitoring (DOM/DDM): Real-time monitoring of transceiver temperature, laser bias current, transmitted optical power, and received optical power.
5. MSA Compliant: Fully adheres to the SFP+ Multi-Source Agreement (SFF-8431).
