The modules below were directly connected with a 30' patch cable.

# SFP - Multimode - Axiom JD118B-AX 850nm
# 3.393 V 4mA
# TX Power -6.332 dBm
# RX Power -7.529 dBm

# SFP - Multimode - Axiom JD118B-AX 850nm
# 3.304V 3mA
# TX Power -6.305 dBm
# RX Power -7.725 dBm

The Mikrotik module below was connected with the same 30' patch cable to the first Axiom SFP module above. The Mikrotik module appears to have lower output power than the Axiom above, but also appears to have better RX by a full dBm.

This particular module appears to have been an anomoly as other modules of the same model tested with -6 dBm TX power.

# SFP - Multimode - Mikrotik S-85DLC05D 850nm
# 3.244V 2mA
# TX Power -9.104 dBm
# RX Power -6.400 dBm

The two Mikrotik modules below are not the same one that was tested above.

# SFP - Multimode - Mikrotik S-85DLC05D 850nm
# 3.283V 3mA
# TX Power -6 dBm
# RX Power -9.485 dBm

# SFP - Multimode - Mikrotik S-85DLC05D 850nm
# 3.237V 3mA
# TX Power -6 dBm
# RX Power -8.786 dBm
