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-C4948E offers superior per-port QoS features to help ensure that network traffic is classified, prioritized, and scheduled optimally to efficiently manage bandwidth-intensive multimedia and time-sensitive and mission-critical applications. The Cisco Catalyst 4948E can classify, monitor, and mark incoming packets, allowing the administrator to differentiate traffic flows and enforce policies. Sharing, shaping, and strict-priority configurations determine scheduling of egress traffic. This high quality Cisco switch works with a number of Gigabit Ethernet SFP optical transceivers. You can easily find these high quality fiber optic transceivers at very competitive rates on Cozlink. What makes this even better that Cozlink also offer you a wide range of patch cords, fiber optic pigtails and high speed cables to choose from and Cozlink also ensure that you get the same day shipping.
