For many years engaged in the sale of optical communications industry, as long as the customer is given a product model, we will know what is the corresponding product. Today we will be Cisco optical module, for example, together with the US to learn about the relevant knowledge SFP-10G-LRM optical module.
What is the SFP-10G-LRM optical module?
SFP-10G-LRM optical module is in line with 10GBase-LRM optical module Gigabit Ethernet standard, low cost, low power, small size characteristics, but also in a wide range of practical applications.
IEEE802.3aq 10GBASE-LRM is a Gigabit Ethernet standard specification, where the "LRM" is the "Long Reach Multimode", refers to the length extension of the multi-point mode, to meet this standard SFP-10G-LRM the optical module mainly for short-distance LAN connections 220m, there is a SFP-10G-LRM2 optical module SFP-10G-LRM optical module upgrade, it may be applied to 2km transmission distance shorter LAN connection.
SFP-10G-LRM optical module What are the characteristics?
● the use of existing serial 10G Ethernet LAN PHY coding sublayer;
● bit error rate does not exceed 10-12;
● 62.5um support multi-mode fiber core: comprises 160 / 500MHz-km and 200 / 500MHz-km (OM1);
● support 50um multimode fiber core: comprises 400 / 400MHz-km, 500 / 500MHz-km (OM2), and 1500 / 500MHz-km (OM3)
● In 500MHz.km minimum support 220 m multimode fiber links has been installed on the selected minimum support multi-mode fiber link 300 meters.
SFP-10G-LRM difference between the optical module and the SFP-10G-LR optical module
● the SFP-10G-the LRM optical module in a multimode optical fiber having a wavelength of 1310nm in a maximum distance of 220m, 10GBASE-LRM supporting standard Ethernet, FDDI networks suitable for data communication and 10G.
● the SFP optical module the LR-1OG- compliance with 10GBase-LR specification on the maximum transmission wavelength of 1310nm single mode fiber a distance of 10km, 25km actually can reach, miniaturization, low power consumption, long distance transmission characteristics .
These are the advantages of the distinction between knowledge SFP-10G-LRM optical module, and the SFP-10G-LR optical module, low cost, low power consumption provides great convenience for network systems, the application is very extensive. Easy communication skylight (ETU-LINK) supplied by the two light modules, stability, highly recognized by the majority of users. In addition, the easy days also provide users with a comprehensive network system solutions to help customers build cost-effective, easy to maintain network systems.
