Fiber LC/SC patch cables and transceiver for NetGear M4300 and M3300 switches
Hi,
We have 2 NetGear M4300 (48 ports + 4 10Gb ports) switches in the server room and need to connect to M3300 (48 ports + 4 10Gb ports) on a different floor via the fiber port. I believe the existing fiber between the floors are 62.5/125 om1/om2 mutimode fiber.
Questions 1: Can I use AXM761 10Gb transceiver on M4300 and M3300 switches?
Question 2: What type of fiber LC-SC patch cable do I need? Does NetGear have a part number for this fiber patch cable?

I also verified with our cable installer that we have 62.5/125 (OM1) between server room and sub closet that less than 722 feet. So if I use AXM763 transceiver on M4300 and S3300 switches, I could get 10Gb speed by using existing fiber 62.5/125 (OM1) cable? Yes if you use AXM763 10GBASE-LRM SFP+ transceiver on M4300 and S3300 switches, you will get 10Gbps speed by using your existing fiber 62.5/125 µm (OM1) cable.
Should I get the 10Gb LC/SC fiber patch cord 50/125 (OM3- aqua) or just stay with 62.5/125 µm (OM1- orange) LC/SC fiber patch cord? You should stay with 62.5/125 µm (OM1- orange) LC / SC-SC fiber patch cord.
We have another sub closet with S3300 switch and using CAT5 or CAT5E (I will need to verify) Ethernet cable to uplink back to server room M4300 switch Ethernet port. Am I getting 10Gb with this configuration? Provided you can use the 10GBASE-T uplinks on the front on both ends, it is possible to achieve 10Gbps speed using CAT6A for full 100 meter (328 ft) run. Using CAT6, it will be less than half that. I'm sorry to tell you that CAT5/CAT5E isn't capable of 10Gbps speed at all when more than couple feet. You can expect that your uplink back to to server room from your CAT5/CAT5E sub closet will be reduced down to 1Gbps speed by both M4300 and S3300 switches.
Assuming this is the case, with 62.5/125 µm (OM1) or 50/125 µm (OM2) fiber, you shouldn't use AXM761 10GBASE-SR SFP+ transceiver, because 10GBASE-LR is designed for 50/125 µm "laser optimized" OM3 and OM4 fiber.
Instead, AXM763 10GBASE-LRM SFP+ transceiver should be used with OM1/OM2 fiber in order to drive 10 Gigabit Ethernet up to 220 m (722 ft) distances.
Yes, AXM763 transceiver has duplex LC connector. If your patch pannel is SC duplex (so SC-SC), yes you need:
a Fiber Optic Patch Cable << Multimode 62.5/125 µm OM1 LC to SC-SC >> if your fiber installation is OM1
a Fiber Optic Patch Cable << Multimode 50/125 µm OM2 LC to SC-SC >> if your fiber installation is OM2
This is very standard fiber optic mulimode patch cable, but we don't sell patch cables at NETGEAR. I hope my indications above will help you procure your patch cables.

Hi Laurent,
Thank you for your quick reply.
You are correct with S3300 (not M3300) in sub closet.
I also verified with our cable installer that we have 62.5/125 (OM1) between server room and sub closet that less than 722 feet. So if I use AXM763 transceiver on M4300 and S3300 switches, I could get 10Gb speed by using existing fiber 62.5/125 (OM1) cable?
Additional questions:
1. Should I get the 10Gb LC/SC fiber patch cord 50/125 (OM3- aqua) or just stay with 62.5/125 (OM1- orange) LC/SC fiber patch cord ?
2. We have another sub closet with S3300 switch and using CAT5 or CAT5E (I will need to verify) Ethernet cable to uplink back to server room M4300 switch Ethernet port. Am I getting 10Gb with this configuration?
