Single-mode fiber optic patchcord 40 m long.

Based on the G657B3 fiber which makes it robust enough to be used as a section from the subscriber's box to the customer.

The use of the prefabricated patchcord  makes the difference that  the iInternet installation at the customer's home does not require splicing . The end of the patchcord  passes through a hole with a diameter of 8mm (although it is more convenient when the hole is 10mm).

In special cases, when for some reason we have a hole with a diameter of 6mm (eg after the existing Ethernet installation) - we should dismantle the connector housing, which will make the patchcord be able to pass through such a small hole.

The cable does not have a  LSZH, it is not fireproof!
