SFP-10G-ZR-S 10GBASE-ZR SFP+ Modules

SFP-10G-SR modules are designed for multimode fiber (MMF), not single-mode. They support 10GBASE-SR short-range links up to 300 meters over OM3 or 400 meters over OM4 fiber, making them suitable for short data center and campus connections rather than the long-haul applications served by ZR modules.

SFP-10G-ER supports 10GBASE-ER transmission up to 40km over single-mode fiber, while SFP-10G-ZR extends reach to 80km. ZR modules use higher-power laser optics and tighter receiver sensitivity specifications to achieve the longer distance, making them the preferred choice for extended long-haul and metro network links.

The SFP-10G-ZR is a 10GBASE-ZR SFP+ module compatible with single-mode fiber (SMF), supporting transmission distances up to 80km. It operates in the SFP+ form factor, delivering 10 Gigabit Ethernet connectivity for long-haul network links, data center interconnects, and service provider backbone infrastructure.

10G SFP+ modules are used to provide 10 Gigabit Ethernet connectivity between switches, routers, and other network equipment over fiber optic cabling. Depending on the variant, they support distances ranging from a few hundred meters (SR) to 80km (ZR), enabling everything from data center links to long-haul carrier networks.

Yes, refurbished modules that undergo rigorous multi-step quality assurance testing and are backed by manufacturer warranties can deliver reliability comparable to new units. Terabit Systems tests each module through a 5-step QA process and backs modules with warranty coverage to ensure dependable long-term performance.

The SFP-10G-ZR-S module is backed by a Cisco Systems warranty along with a 1-year replacement or full refund guarantee. If a unit is found defective within the warranty period, an RMA process is available to resolve the issue quickly and minimize network downtime.
