The Cisco SFP-10G-LR datasheet shows information regarding its different models and capacities. This can help in the decision of a client on which model they should be getting. Before considering which module to buy, find out some of the compatibility factors for your system and the modules.
Link length is an important factor to consider before purchasing a module. The Cisco SFP-10G-LR datasheet shows the different ranges that the different modules can support. The shortest link length that can be supported by LR modules is 300 meters. This connection type is the standard single-mode fiber. The S-Class module can support a link length of 10 kilometers, perfect for traversing multiple floors of a building. There are also modules that can support 10 kilometers of link length while enduring an extended operating temperature range, namely the LR-X module.
Most LR modules support only single-mode fiber connections. This means that these cables are made for longer distances and higher bandwidth, perfect for companies needing connections over long distances such as telecommunications and servers, as well as buildings.
The single mode fiber has a core and a cladding. The core measures 9 microns normally while the cladding is 125 microns. This is different from the multimode fiber optic cable, with 50 microns to 123 microns and 62.5 microns to 125 microns. This allows for more simultaneous data transfers, but these are made for short distances only. So if you are looking for LR transceiver modules, then you are probably in need of long distance connections.
There are available SFP-10G-LR modules that can be bought new or used for companies that require it. This can significantly reduce the cost of acquiring a new part for your system. Factoring these options as well as the link length and fiber modes can be done with the help of the Cisco SFP-10G-LR datasheet.
