    We are looking at implementing some JL479A (8320) and JL661A (6300M) switches.  Some of our fiber connections are greater than 40km.  Do these models of switch support 10/40g ZR modules for the 8320 and 10g ZR modules for the 6300M?

    Thanks in advance!

    Speaking about a distance longer than 10 km (and up to 40 km) the entire Aruba 8320 switch series (including the SKU JL479A) supports the Aruba 40G QSFP+ LC ER4 40 km SMF Transceiver (SKU Q9G82A) connected to a standard 9/125 um (No FEC) Single Mode Fiber Optic cable for up to 30 km only, to reach the 40 km distance a 9/125 um FEC (Forward Error Correction) is required on both ends of the engineered link. 

    Up to 40 km of a (engineered) link at 10G speed instead can be served by using J9153A or J9153D SFP+ LC ER Transceivers on the SKU JL479A Switch.

    This is what is reported looking at latest Aruba AOS-Switch and AOS-CX Transceivers Guide (Edition 12).
