HP JH892A Arista 40Gb/s 40GBase-XSR4 QSFP+ Transceiver Module

Product Description

The HP JH892A is a high-performance QSFP+ (Quad Small Form-factor Pluggable Plus) transceiver module, manufactured by Arista, designed to support 40 Gigabit Ethernet (40GbE) network connections. This module adheres to the 40GBase-XSR4 standard, which typically indicates the use of parallel optics to achieve its high bandwidth over a specific fiber type and distance. The XSR4 designation suggests it is optimized for short reach applications, often within data centers. This transceiver module is engineered for demanding network environments where high throughput and low latency are critical. Its QSFP+ form factor allows for a compact and high-density port configuration on network switches and routers. The 40GBase-XSR4 standard implies that it utilizes multiple lanes of fiber (often 4 lanes of 10Gbps) to aggregate the total 40Gbps bandwidth, making it suitable for inter-switch links or server connections within a rack or across short distances. The JH892A is a hot-pluggable module, meaning it can be installed or removed from network equipment without powering down the device, ensuring network uptime and flexibility. Its primary application is in data center networking, facilitating high-speed data transfers between switches, servers, and storage devices, thereby supporting the growing demands of modern IT infrastructures.
