Cisco 10Gb SFP+ modules are hot-swappable, compact optical transceivers that provide 10 Gigabit Ethernet connectivity for various networking environments. They feature digital optical monitoring, support hot-swapping, and offer "pay-as-you-populate" investment protection.
Key Features of Cisco 10Gb SFP+ Modules:
Smallest 10G Form Factor:
SFP+ modules are designed to be compact, enabling high density per chassis.
Hot-Swappable:
These modules can be installed or replaced without powering down the switch, offering flexibility and ease of maintenance.
10GBASE Ethernet Support:
They are designed to support 10 Gigabit Ethernet standards.
Digital Optical Monitoring (DOM):
Provides diagnostic capabilities, allowing for monitoring of the transceiver's performance and status.
Cisco Quality Identification (ID):
Enables Cisco platforms to identify and verify if the module is certified by Cisco.
Optical Interoperability:
They can interoperate with other 10GBASE interfaces like XENPAK, X2, and XFP.
"Pay-as-you-populate" Model:
This feature allows for investment protection and ease of technology migration, as you can add modules as needed.
Different 10Gb SFP+ Modules:
Cisco offers various 10Gb SFP+ modules, each designed for different environments and distance requirements:
SFP-10G-SR:
Designed for short-reach data transmission over multimode fiber (MMF), typically up to 300 meters.
SFP-10G-LR:
Designed for longer-reach data transmission over single-mode fiber (SMF), typically up to 10 kilometers.
SFP-10G-ER:
Designed for even longer-reach data transmission over single-mode fiber, typically up to 40 kilometers.
SFP-10G-ZR:
Designed for very long-reach data transmission over single-mode fiber, typically up to 80 kilometers.
SFP-10G-T:
Uses copper cables for 10GbE connections, often in data center environments.
Applications:
Data Centers:
SFP+ modules are commonly used in data centers for connecting servers to switches.
Enterprise Networks:
They can be used for high-speed connectivity within enterprise environments.
Service Provider Networks:
SFP+ modules are also used by service providers for long-haul transmission.
