Type Of Tutorial SFP Switch

Cisco WS-CBS3125G-S Switch Overview

WS-CBS3125G-S belongs to the Cisco Catalyst 3120G Series Switches, it widely used in the campus local area network (LAN) access. The Cisco Catalyst Blade Switch 3120G represents the next-generation networking solution for blade server environments. Built on the market-leading Cisco hardware and Cisco IOS Software, the Cisco Catalyst Blade Switch 3120G is engineered with unique technologies specifically designed to meet the rigors of blade server-based application infrastructure. Specifically, the switch is designed to deliver scalable, high-performance, highly resilient connectivity while supporting ongoing IT initiatives to reduce server infrastructure complexity and total cost of ownership (TCO).

How to determine what types of optical transceivers for Cisco switches?

1. Finding the corresponding optical module compatibility matrix via Cisco official website. 
2. On the running switches, enter the privileged mode and input # "show idprom interface gi1 / 0/48" command, you can query the optical module model and serial number, If not, try to input other two commands: xuxic or show idprom int g2/6
3. Checking the type and port based on the specification, it can be used as long as it is gigabit SFP optical module interface. But the specific models to be decided according to the actual demand, such as type, the actual use of distance, single-mode or multimode, single fiber or dual fiber etc. Welcome to consult Cozlink engineer.

Summary

The Cisco WS-CBS3125G-S has two configurations and SKUs. One configuration allows customers to connect the switch to the existing network fabric using Gigabit Ethernet uplinks, and the other configuration allows customers to connect the switch to the existing network fabric using Gigabit and 10 Gigabit Ethernet uplinks. These switches are compatible with various Gigabit Ethernet SFP optical transceivers. All these fiber optic transceivers are available on Cozlink at really competitive prices. You can expect same day shipping on Cozlink. Not just optical transceivers, you can also find fiber optic pigtails and high speed cables for your choice on Cozlink.
