Q:

Could you please let me know if I need an attenuator required at the receiver end if I was to use a 1 or 2 meter fibre patch cord between transmitter and receiver using P/N: SFP28-25GLR-31. Not sure if it overload the receiver? Thanks

by D***l on 11/18/2021

A:

Whether the connection needs attenuation shall be subject to the actual link loss and measured value. The average optical power of this LR module is -4.3 ~ +4.5dBm, and the receiving overload is 3.5dBm. Based on theoretical value of link loss (0.35dbm/km) at 1310nm, the max TX power- receiving overload = 1dB, 1 / 0.35 = 2.9km. There is no need to add an attenuator for distances over 3km. For connections of 1 to 2m, 1dB ~ 3dB attenuation can be added to protect the modules.

Need some SFP-25G-LR modules for our data center. Our switch type is Cisco NCS 55A2. These 25G transceivers have passed our performance tests and worked great on our switches. Thumbs Up on this product.
