HPE 455886-B21 10Gb SFP+ LR Transceiver Maximum Distance 10km
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:
- 10GbE Connectivity: Supports data rates up to 10.3125 Gbps.
- Long-Range Capability: Transmits data up to 10 km on 9/125µm Single-Mode Fiber (SMF).
- Hot-Swappable: Allows for installation without powering down the host device, minimizing downtime.
- Digital Optical Monitoring (DOM/DDM): Real-time monitoring of transceiver temperature, laser bias current, transmitted optical power, and received optical power.
- MSA Compliant: Fully adheres to the SFP+ Multi-Source Agreement (SFF-8431).
