Thanks for inquiring on FS.COM. It is recommended to choose Cisco compatible modules for an adnet an-um-SMC-24-AS and Unifi switch. The optic #12622 can work well on these two switches with SFP ports. By J***g on 09/02/2020

Kindly noted that #12622 is suitable for Ethernet application. It cannot be used with your ISP GPON. Could you provide the ISP GPON model and parameters? Then we will check if there is a suitable product for you. By J***g on 07/15/2020

Yes, this module is backward compatible with 1.25G, 622M, 155M three rates. By J***r on 03/10/2020

This optic #12622 can also operate up to 550 m on any multimode fibers. When used over legacy multimode fiber type, the transmitter should be coupled through a mode conditioning patch cable. It's the same as Cisco LH optic. By *** on 09/26/2019

Thanks for your question. The FORTINET FAD-200F does not have a SFP port that can be used with the module. It is equipped with an RJ-45 port, so you can use Cat6a Patch Cables #66789 directly. By *** on 05/27/2019

Dust and contamination can accumulate on transceiver's connectors and cause problems such as reducing the optic launch power. To ensure better connection, FS.COM strongly recommends cleaning both connectors each time you disconnect and reconnect them. FS.COM High Quality One-Push Fiber Optic Pen Cleaner for 1.25mm LC/MU Connector is the best cleaning choice for 1000BASE-LX SFP transceivers. By K***n on 03/29/2017
