Cisco SFP-10G-SR VS. Cisco SFP-10G-LR
The 10G SFP+ modules allow a wide variety of 10 Gigabit Ethernet connectivity options for enterprise, data center, and service provider transport applications. A single piece of hardware can accommodate a wide variety of cable and connection types, simply by substituting transceiver for the connector being used. Unfortunately, this also means that finding the right SFP+ transceiver for your application can sometimes be confusing and difficult, because many connection types exist: SFP-10G-SR, SFP-10G-LR, SFP-10G-LRM, SFP-10G-ER, SFP-10G-ZR, SFP-10G-T-S, CVR-XENPAK-SFP10G and CVR-X2-SFP10G. This article mainly talks about the difference between Cisco SFP-10G-SR and Cisco SFP-10G-LR. Overview of SFP+ The SFP+ is the enhanced small form-factor pluggable. It is also called SFP 10G to avoid confusion with the 1G version (SFP). It has the same shape as the SFP, but SFP+ can support data rates up to 10 Gbit/s. Specifically, it can support 8 Gbit/s on Fibre Channel and 10 Gbit/s on Gigab...
