HPE Aruba 1990-4657 10G Sfp SMF XCVR Transceiver Module

The HPE 1990-4657 is an SFP+ transceiver module designed for reliable, high-speed 10 Gigabit Ethernet connectivity over long distances within enterprise and data center networks. It addresses the need for extending network reach beyond the limitations of standard copper or short-range optical cabling, providing a stable 10GbE link for core-to-distribution or inter-building connections. This module is engineered for seamless integration with compatible HPE Aruba networking equipment, ensuring carrier-grade performance. At its core, the transceiver utilizes the 10GBASE-LR standard, transmitting data over single-mode fiber optic cables. This technology enables connections up to 10 kilometers by using a 1310 nm wavelength laser, which minimizes signal degradation over extended paths. The result is a robust and error-free data link, critical for applications that require high bandwidth and low latency between physically separated network segments, such as connecting a main data center to a remote office building or linking network closets across a large campus. Engineered for straightforward deployment, the 1990-4657 features a hot-swappable, plug-in SFP+ form factor that simplifies installation and maintenance without requiring device downtime. It plugs directly into an SFP+ port on a compatible switch or router, utilizing standard duplex LC connectors for fiber termination. This allows network administrators to easily upgrade existing infrastructure to 10GbE or establish new long-haul links with minimal configuration, managed directly through the host device’s command-line interface or graphical user interface.
