40m/131.2ft Outdoor and Indoor Shielded Armored Fiber Optic Cable LC/UPC to LC/UPC OM3 Multimode Duplex 50/125μm LSZH, Black 40 Meters

Works well for what I wanted. I was tired of my mesh WiFi less than optimal performance (half or less my broadband line speed throughout the house) so bought a pair of SFP+/2.5Gbps switches and linked downstairs router to my upstairs office and now get full speed wired and faster WiFi (about 75% line speed).

I've a 10Gbps switch upstairs and another 10Gbps switch downstairs (behind the telly) each with a 10Gbps SFP+ I needed to link the two together in order to have my whole home network running at 10Gbps.The ISP service is 1.2Gbps and I'm preparing now for the to-come 5Gbps and 10Gbps services where I hope the ISPs drop the latency to sub-5ms, 1ms would be my preference. ;-).The routing the fibre took was: From my study, into the attic, into 5m of 27mm conduit along with two other outdoor CAT8 cables, under the roof tiles (~4m), out via the eaves, down the back of the downpipe, into the living room via a hole drilled in the exterior wall (same route as the Virgin Media coax).During that process this fibre was pushed, pulled, squeezed, dropped on the ground, bent (not violating the min bend radius), taped/untaped into a bundle of cables and finally secured using velcro. And at no time was I in any way concerned about the wellbeing or structural integrity of this duplex fibre.If you know anything about SFPs then you'll know that unless you specifically pay A LOT for multi-rate SFPs (1Gbps/5Gbps/10Gbps) then they only operate at their SINGLE published rate. I'm running generic Amazon single rate 10Gbps SFP+ (~£15 a pop) in my two 10Gbps switches and my LAN ping times are sub 1ms and 100% reliable.Buy with confidence.

Robust cable and stood quite a lot of movement when being pulled around gritstone walls and through metal shroud.The fiber cable is somewhat easy to work with and can handle the odd tight bend when quickly undone again.Managed to maintain my full 10Gb as expect.

Strong and flexible. Have used it for an external installation and it has done the job. Full 1gbs speeds seen.

I bought 2 drums of this multimode fibre for Blackmagic Mini fibre converters. It works but only up to 300m (max). Go and buy single mode fibre though as this is the actual spec you should use and then you can go up to 13miles (roughly).I'm aware this is 150m so it does work, but i bought another 200m and tried to join them and then had drop outs.

Spent an afternoon wondering why switches could only negotiate a 1G link but failed to sustain a 10G link. Turns out the cable is single mode, labelled everywhere online as OM3, but on the packet and cable itself, it is single mode G652D.Update: I emailed Elfcam who replied very quickly and confirmed Amazon have an issue with inventory. Elfcam have been great at resolving the issue, 10/10 customer service.Update 2: Elfcam have confirmed Amazon have fixed the inventory issue, updated to 5*.

Perfect cable to link the main switch to my garage switch at 10Gb.happy camper

Tested and works with ubiquiti using a transceiver. But it is definitely not armour, they really should not be able to advertise it in that way! that is my only issue though. Apart from that, it works
