Cisco 10GBASE-LR SFP Module for 10-Gigabit Ethernet Deployments, Hot Swappable, 5-Year Standard Warranty (SFP-10G-LR=)

Product Information

Cisco 1000BASE-EX SFP transceiver module for SMF, 1310-nm wavelength, extended operating temperature range. Extended warranty (optional): Cisco SFP+ modules can be covered in a Cisco SMARTnet® Service support contract for the Cisco switch or router chassis LRM transceivers are often mistaken for 10GBASE-LR SFP+ optics, but it is not the same. 10GBASE-LRM SFP+ makes use of the 1310nm lasers, however, it has a maximum reach of only 220 m over standard multimode fibers such as OM3/OM4. This transceiver is available in the XFP and SFP+ form factors. So you have bought an expensive Cisco original brand switch. Now you are considering buying compatible optics for the same. But, do you really need to buy Cisco original brand modules?

This one is actually pretty easy. SR stands for Short Reach, and LR stands for Long Reach. SR transceivers are almost always multi-mode, and optimized for high speeds over relatively short distances. However, the much higher-powered OM3 and OM4 formats can push that into the hundreds of meters for a single cable.To begin with, 10G SFP+ optical transceivers are easily available in the market and are now a mature technology. They are not too expensive. 40G/100G optical modules are commonly used in data centres and enterprises around the world for interconnection. The 10G SFP+ modules have many different standards such as SFP-10G-LR, SFP-10G-SR, 10GBASE-LRM SFP+ and 10GBASE-ER SFP+. We have focused on the factors that separate SFP-10G-SR from SFP-10G-LR.

Whenever you see -X, that means it has extended ability to operate under wider temperature variation, from-40°C to 85°C(-40°Fto 365°F). There is no other significant difference from the standard versions, and no reason to use -X equipment unless you're operating in extreme temperatures.

Aside from these differences, an S-Class transceiver is identical to the equivalent non S-Class variation. So, for most standard applications, S-Class is fine and will save some money compared to other Cisco transceivers. The SFP-10G-BX40D-I and SFP-10G-BX40U-I SFPs support Digital Optical Monitoring (DOM) functions according to the industry-standard SFF-8472 Multisource Agreement (MSA). This feature gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device. Cisco 1000BASE-LX/LH SFP transceiver module for MMF and SMF, 1300-nm wavelength, extended operating temperature range. The Cisco 10GBASE-LRM Module also supports link lengths of 300m on standard Single-Mode Fiber (SMF,G.652).Information about Cisco’s environmental sustainability policies and initiatives for our products, solutions, operations, and extended operations or supply chain is provided in the “Environment Sustainability” section of Cisco’s Corporate Social Responsibility (CSR) Report.

The SFP-10G-BXD-I and SFP-10G-BXU-I SFPs also support Digital Optical Monitoring (DOM) functions according to the industry-standard SFF-8472 Multisource Agreement (MSA). This feature gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
