What customers say
Customers overwhelmingly praise this transceiver for its exceptional value and flawless compatibility. A major theme is the instant recognition across Cisco Catalyst and Nexus platforms, eliminating complex configuration often associated with non-OEM optics. Users report stable, high-speed 10G links that match the performance of much costlier modules. Network engineers value the module's reliability, noting consistently low error rates even under heavy data center loads. The core appeal is significant cost savings, offering a financially viable alternative that maintains network integrity. This module has converted skeptics into loyal users by effectively eliminating the premium price barrier for essential network components.
Know before you buy
The main difference is the operating temperature range. This module is built to function reliably in extreme environments from -40°C to 85°C, making it suitable for factory floors or outdoor enclosures where standard commercial transceivers would likely fail.
Yes, this transceiver is designed to be SFP+ MSA compliant, which ensures seamless interoperability across a wide range of networking equipment from various vendors.
The maximum reach depends on your fiber type. You can achieve up to 300 meters using OM3 multi-mode fiber or up to 400 meters using OM4 multi-mode fiber.
Yes, it features Digital Diagnostics Monitoring (DOM). This allows you to monitor critical parameters like optical output power, input power, and temperature in real-time to help troubleshoot potential link issues.
No, this module is hot-pluggable. You can insert or remove it from an SFP+ port while the switch is powered on without interrupting the operation of other ports.
This module requires a multi-mode fiber (MMF) cable equipped with a Duplex LC connector.
