Cisco sfp 10g lr vs sfp 10g lr s

From their appearance and definition, SFP-10G-LR-S and SFP-10G-LR may be the same, but actually they have some differences in their protocols, temperatures and price.

Protocol:

SFP-10G-LR can support three protocols including Ethernet, OTN(Optical Transport Network) and WAN-PHY(Wide Area Network Physics). However, SFP-10G-LR-S can just support Ethernet protocol. In addition, SFP-10G-LR-S does not have TAA compliance.

Temperature Range:

SFP-10G-LR-S and SFP-10G-LR transceivers have different temperature ranges. But the operating temperature range of SFP-10G-LR-S is smaller, so SFP-10G-LR-S is better for shorter transmission distance applications than SFP-10G-LR. If you design a project for an enterprise or data center environment that does not need too long distance, temperature tolerances, or other special request, SFP-10G-LR-S should be just fine for you.

Price:

Compared with SFP-10G-LR, SFP-10G-LR-S doesn’t have too many specials. And the performance of SFP-10G-LR-S are no better than that of SFP-10G-LR. But why do so many people insist to select SFP-10G-LR-S? This is because SFP-10G-LR-S has lower prices.

What are Cisco sfp 10g lr and sfp 10g lr s, respectively?

Basic Knowledge About SFP-10G-LR-S

Certainly! The SFP-10G-LR-S is a specific optical transceiver module produced by Cisco. Here's some foundational knowledge about it:

1. Module Type: The SFP-10G-LR-S is an SFP+ (Small Form-Factor Pluggable Plus) module. The SFP+ format is an upgraded version of the SFP interface capable of supporting data rates up to 10 Gbps.

2. Speed: As the name suggests, this module is designed to support 10 Gigabit Ethernet data rates.

3. Distance/Range: The "LR" in its name stands for "Long Range". Typically, this indicates that the module can handle transmission distances of up to 10 kilometers (km) over single-mode fiber (SMF).

4. Wavelength: It operates at a 1310 nm wavelength, which is standard for long-range transmissions over SMF.

5. S-Class: The "S" in SFP-10G-LR-S indicates that this module belongs to Cisco's "S-Class" or Standard optics offering. These are usually more cost-effective options that provide the necessary functionalities without some of the bells and whistles of the more premium modules.

6. Digital Optical Monitoring (DOM): This module supports DOM, which allows users to monitor the real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

7. Fiber Type: As mentioned, it's designed for single-mode fiber (SMF) due to its long-range transmission capabilities.

8. Connector Type: The SFP-10G-LR-S module typically uses a standard LC duplex connector.

9. Applications: This transceiver is suitable for 10G Ethernet and other high-speed data connections. It's commonly used in data centers, metro networks, and sometimes in larger enterprise networks.

10. Compatibility: While Cisco modules are intended for Cisco equipment, there's often a debate about using OEM (original equipment manufacturer) vs. third-party transceivers. It's recommended to check Cisco's compatibility matrix to ensure the module will function correctly with specific equipment models.

11. Temperature Range: These modules often come with a commercial temperature range, but specifics should always be checked in the datasheet.

12. Compliance: The SFP-10G-LR-S, like many transceivers, adheres to multiple industry standards to ensure it will function properly in its intended role.

When selecting transceivers like the SFP-10G-LR-S, it's crucial to understand your network's requirements, such as distance, data rate, and the type of fiber being used, to ensure you choose the right module for your needs.

Basic Knowledge About SFP-10G-LR

Certainly! The SFP-10G-LR is also a popular optical transceiver module produced by Cisco. Here's a basic rundown of its features and specifications:

1. Module Type: The SFP-10G-LR is an SFP+ (Small Form-Factor Pluggable Plus) module. SFP+ is the evolution of the older SFP design and supports data rates up to 10 Gbps.

2. Speed: This module supports 10 Gigabit Ethernet data rates, aligning with its SFP+ designation.

3. Distance/Range: The "LR" in its name signifies "Long Range." This means the module is designed for transmission distances of up to 10 kilometers (km) over single-mode fiber (SMF).

4. Wavelength: It operates on a 1310 nm wavelength, which is common for long-range transmissions over SMF.

5. Fiber Type: The SFP-10G-LR is intended for single-mode fiber (SMF) due to its long-range transmission capabilities.

6. Connector Type: This module typically employs an LC duplex connector.

7. Applications: Commonly used in a variety of settings, including data centers, metropolitan area networks (metro networks), and larger enterprise networks for high-speed data connections.

8. Digital Optical Monitoring (DOM): Like many modern transceivers, the SFP-10G-LR supports DOM, which allows users to monitor the real-time parameters of the SFP, including optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

9. Compatibility: While Cisco modules are ideally suited for Cisco equipment, there's an ongoing debate about the use of OEM (original equipment manufacturer) vs. third-party transceivers. Always refer to Cisco's compatibility matrix to ensure that the module will work seamlessly with the intended equipment.

10. Temperature Range: It generally has a commercial temperature range. Specifics, however, should always be confirmed in the product datasheet.

11. Compliance: The SFP-10G-LR adheres to numerous industry standards, which ensures that it performs as expected in its intended applications.

12. No "S" at the End: Unlike the SFP-10G-LR-S, this model doesn't have the "S" at the end. This means it's from Cisco's premium line of transceivers, which might offer more features or better performance in some scenarios compared to the S-Class transceivers.

When selecting transceivers like the SFP-10G-LR, it's crucial to be familiar with your network's requirements to ensure you're making a suitable choice. This involves knowing the intended distance, data rate, type of fiber, and other relevant specifications.
