Keep critical Fibre Channel paths available with a long-wave SFP designed for storage and SAN environments that depend on consistent optics. This AddOn compatible module matches the QLogic SFP4-LW-JD1 form factor and delivers 4 Gbps Fibre Channel signaling for infrastructure teams standardizing on proven transceiver replacements. TAA compliance supports federal and regulated procurement requirements, while the compatible design helps simplify refreshes, spares planning, and lifecycle support across mixed hardware estates. For teams maintaining legacy Fibre Channel fabrics, this module offers a practical way to preserve link integrity without overpaying for original-branded optics. Use it where dependable long-wave connectivity matters more than marketing claims: in storage uplinks, switch interconnects, and replacement inventories that must be ready when a failed optic takes a port offline. AddOn’s compatibility focus makes this a straightforward choice for organizations that value verified fit, sourcing clarity, and controlled spend.
