400 metre armoured singlemode cable

This 400 metre LC to LC duplex cable uses 9/125 singlemode fibre for long-distance outdoor links. The metal-armoured jacket protects the glass core while maintaining flexibility during installation. It is built for campus, campus-to-building or telecoms runs where standard patch cords would fail. The ceramic LC/PC connectors are factory polished for low insertion loss.

Outdoor durability and signal integrity

The armoured sheath resists crushing, rodent damage and UV exposure while the outer jacket handles rain and sunshine. Ceramic ferrules keep insertion loss low and return loss high across the full 400 metre span. No active components mean zero power draw and silent operation in any environment. The cable is tested end-to-end before shipment.

Installation constraints and compatibility

The weatherproof cover is rated for direct sunlight and rain but the manufacturer advises against direct burial or aerial suspension without additional support. It mates with any standard LC/PC port on switches, media converters or patch panels. No software, drivers or licensing are required; the link is purely passive. Buyers needing burial-grade or aerial-rated cable should select a different construction.

Questions about this item

How do I install the LC connectors without cracking the ceramic ferrules on this 400M armored duplex cable?

Remove the weatherproof boot, align the key on the LC ferrule with the adapter slot, and push straight in until the latch clicks; forcing it at an angle is the step that chips the ceramic tip.

What maintenance will the metal-armored jacket on this 9/125 singlemode cable need after outdoor exposure?

Inspect the outer jacket annually for cuts or UV cracking, clean LC end-faces with a lint-free wipe and isopropyl alcohol before each reconnect, and replace any connector that shows pitted ferrules.

What distance limit appears first when running 1 Gbps traffic continuously over the full 1312 ft length?

At 400M the primary limit is the accumulated insertion loss budget of the LC/PC connectors and the 9/125 fiber itself; exceeding the loss budget causes errors before any bandwidth ceiling is reached.
