What customers say
Customers overwhelmingly praise the Cisco SFP for its exceptional reliability and guaranteed interoperability with Cisco gear, calling it the standard for enterprise fiber. Reviewers consistently report seamless plug-and-play setup, avoiding common compatibility errors associated with third party modules. The stability under heavy network load is a key benefit, ensuring zero link drops for mission critical infrastructure. While the performance justifies the investment in high stakes settings, the primary friction point remains the premium cost. Many users feel the steep price diminishes the overall value proposition compared to functionally similar, less expensive alternatives, despite acknowledging the security of official support.
Know before you buy
This module is designed specifically for multi-mode fiber optic cabling with a 62.5 µm standard. It utilizes an LC/PC Duplex connector for your network connections.
Yes, this is a hot-swappable SFP module. You can install or remove it from a powered-on Gigabit Ethernet port without needing to shut down or reboot your network equipment.
Because this module is MSA (Multi-Source Agreement) compliant, it offers broad industry-standard compatibility. While it is optimized for Cisco hardware, such as the 3270 Rugged Integrated Services Router, it can often function in other MSA-compliant devices.
The 'RGD' designation stands for 'Rugged.' This version of the module is built to withstand more demanding environmental conditions, making it suitable for industrial or outdoor deployments where standard modules might fail.
This 1000BASE-SX transceiver operates at a wavelength of 850 nm, which is the standard for short-range, multi-mode fiber Gigabit Ethernet transmissions.
