Keep legacy and mixed-speed copper links active without changing the switch side. This AddOn 4-pack of Citrix ACC-SFPC compatible SFP transceivers delivers 10/100/1000Base-T connectivity over RJ-45 copper, with reach up to 100 m for standard structured cabling runs. It is designed for data networking environments where predictable interoperability matters, and it supports 10/100/1000Base auto-negotiation to match the connected device. Built for Citrix NetScaler platforms and MSA-compliant deployments, this TAA-compliant module set gives procurement teams a practical alternative to OEM-branded optics without sacrificing compatibility requirements. The copper interface is useful when fiber is unnecessary, when existing Cat5e/Cat6 plant is already in place, or when you need a direct replacement for short-reach access links. Operating support from 0 to 70 C helps it fit typical enterprise rack conditions, while the 3-year limited warranty adds confidence for long-term standardization.
