This category focuses on standardized SFP+ form factor optics optimized for multimode fiber environments where low latency, high throughput, and predictable signal integrity are essential. Within Aruba and Hewlett Packard Enterprise networking portfolios, 10G SFP+ SR transceivers are widely deployed to interconnect access, aggregation, and core switching layers with consistent performance characteristics.

This category emphasizes compatibility, stability, and operational efficiency across Aruba switches and routers that support SFP+ slots. The 10G SR optical segment is particularly valued in structured cabling infrastructures where OM3 multimode fiber is already installed, allowing organizations to upgrade bandwidth capacity without replacing cabling. The Aruba 1990-4634 transceiver reflects the maturity of this category by delivering predictable optical reach, standards compliance, and enterprise-class reliability.

Optical Standards and IEEE Compliance

10G SFP+ SR transceivers operate in accordance with IEEE 802.3ae and subsequent 10-gigabit Ethernet standards that define short-range optical transmission over multimode fiber. This category uses an 850 nm wavelength laser source optimized for high-speed data signaling across OM3 and OM4 fiber types. The Aruba 10G SFP+ SR module adheres to these standards to ensure seamless interoperability within compliant network architectures.

Standards compliance in this category ensures consistent encoding, signal modulation, and power levels, enabling predictable performance across multi-vendor environments when deployed within supported ecosystems. Aruba-branded optics, including the 1990-4634 model, are engineered and validated to meet strict tolerances for insertion loss, optical dispersion, and thermal stability. These characteristics make the category suitable for mission-critical enterprise networking where uptime and data integrity are non-negotiable.

850 nm Short-Reach Optical Architecture

The 850 nm optical design is a defining attribute of the 10G SFP+ SR category. This wavelength allows cost-effective laser manufacturing while supporting high data rates across multimode fiber. The Aruba 1990-4634 transceiver uses this wavelength to achieve distances of up to 300 meters on OM3 fiber, making it ideal for data halls, wiring closets, and campus interconnections.

Short-reach optics in this category are optimized for environments with controlled distances and structured fiber layouts. They deliver low power consumption and reduced heat output compared to long-reach alternatives, contributing to improved energy efficiency within dense switching deployments.

IEEE and MSA Interoperability

Modules in the 10G SFP+ SR category conform to multi-source agreement specifications that define the physical and electrical interface of SFP+ optics. This compliance allows network administrators to maintain standardized deployment practices while benefiting from vendor-specific validation. The Aruba 1990-4634 transceiver is designed to function seamlessly within Aruba switches that recognize and manage supported optics for optimal performance.

Multimode Fiber Compatibility and Cabling Infrastructure

A defining characteristic of the Aruba 10G SFP+ SR transceiver category is its reliance on multimode fiber, specifically OM3 MMF, for short-range connectivity. OM3 fiber is widely deployed in enterprise and data center environments due to its balance of performance and cost. This category enables organizations to maximize the value of existing fiber investments while achieving 10-gigabit speeds.

The LC duplex connector format used in this category provides a compact and secure physical interface that supports high port density on switches and patch panels. The Aruba 1990-4634 transceiver integrates seamlessly into LC-terminated fiber links, supporting clean signal transmission and simplified cable management.

OM3 Fiber Performance Characteristics

OM3 multimode fiber supports laser-optimized transmission at 850 nm, enabling distances of up to 300 meters for 10G Ethernet signals. This performance envelope aligns precisely with the design parameters of the Aruba 10G SFP+ SR category. The fiber’s modal bandwidth minimizes signal distortion and ensures consistent throughput across supported distances.

By leveraging OM3 fiber, this category supports scalable network designs where switches can be interconnected across floors or rows without requiring single-mode fiber or more expensive long-reach optics.

LC Duplex Connector Design

The LC connector is a critical component of the SFP+ SR transceiver category. Its small form factor allows higher port densities on network equipment, supporting modern data center designs where space efficiency is paramount. The Aruba 1990-4634 transceiver utilizes a precision-engineered LC interface to maintain proper alignment and minimize insertion loss.
