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 N7K-M148GS-11= switch delivers 40 Gbps of bandwidth in each direction. Traffic destined for a different module is distributed across up to five fabric modules. At least one fabric module is required in the chassis. Two fabric modules installed in the chassis delivers fabric fault tolerance with no loss of bandwidth. Just like all other switches from this series this particular model's also works with a lot of Gigabit Ethernet SFP optical transceivers which can be found in Cozlink with high quality and competitive price. Moreover, most of them have adequate inventory, which ensures the customers to enjoy same day shipping. In addition to providing optical transceivers, Cozlink also offers patch cords, fiber optic pigtails and high speed cables for your choice.
