Cisco SFP-10G-SR-S vs SFP-10G-SR
Introduction:
When it comes to networking equipment, Cisco is a renowned name that offers a wide range of products to meet the needs of businesses and organizations. Two popular transceiver modules offered by Cisco are the SFP-10G-SR-S and SFP-10G-SR. In this article, we will compare these two modules in terms of their specifications and features to help you make an informed decision.
1. Cisco SFP-10G-SR-S:
The Cisco SFP-10G-SR-S is a 10 Gigabit Ethernet transceiver module designed for short-range communications. It supports a maximum data transfer rate of 10 Gbps and operates over multi-mode fiber cables with a maximum reach of up to 300 meters. This module uses a 1310nm wavelength and is compatible with the SFP+ (small form-factor pluggable plus) interface. It is hot-swappable, allowing for easy installation and replacement without interrupting network operations.
The SFP-10G-SR-S also features digital optical monitoring (DOM) functionality, which provides real-time monitoring of vital parameters such as temperature, voltage, and transmit/receive power levels. This allows for efficient troubleshooting and performance optimization.
2. Cisco SFP-10G-SR:
The Cisco SFP-10G-SR is another 10 Gigabit Ethernet transceiver module that operates at a data rate of 10 Gbps. It is also designed for short-range communications but operates over OM3 and OM4 multi-mode fiber cables with a maximum reach of up to 400 meters. This module uses a 850nm wavelength and is compatible with the SFP+ interface.
Similar to the SFP-10G-SR-S, the SFP-10G-SR is hot-swappable and supports DOM functionality for real-time monitoring. It is widely used in data centers, enterprise networks, and high-performance computing applications.
3. Comparison:
a. Reach: The SFP-10G-SR-S has a maximum reach of 300 meters, while the SFP-10G-SR can reach up to 400 meters. If long-range connectivity is required, the SFP-10G-SR may be a better choice.
b. Wavelength: The SFP-10G-SR-S uses a 1310nm wavelength, whereas the SFP-10G-SR uses an 850nm wavelength. This difference may influence compatibility with fiber optic cables used in your network infrastructure.
c. Cable Compatibility: The SFP-10G-SR uses OM3 and OM4 multi-mode fiber cables, while the SFP-10G-SR-S is designed for general multi-mode fibers. It is important to consider the compatibility of these modules with your existing cabling infrastructure.
d. Price: The pricing of these modules may vary, with the SFP-10G-SR typically being slightly more expensive due to its extended reach capability.
Conclusion:
Both the Cisco SFP-10G-SR-S and SFP-10G-SR offer reliable and high-performance connectivity solutions for short-range communications. The SFP-10G-SR-S is suitable for distances up to 300 meters, making it ideal for data centers and local area networks. On the other hand, the SFP-10G-SR can provide extended reach of up to 400 meters, making it a better choice for larger network deployments. Consider the specific requirements of your network infrastructure and choose the module that best meets your needs.
