Optical Network for U1

Currently we do not have plan to introduce any hardware changes to U1.

For optical-based network isolation for Lumin products (other than X1 which has built-in SFP port for optical network), there are two ways to do it.

Expensive way:

(Note that there is an incompatibility report with Netgear Mesh product.)

Inexpensive way:
A cheaper alternative to do fiber network isolation is to use a pair of fiber media converters (FMC) in a setup like this:

WiFi router or network switch - (LAN cable) - FMC - (fiber) - FMC - (LAN cable) - Lumin

Lumin T2 / D2 / M1 / U1 (MINI): Use a pair of TP-Link MC210CS

Lumin S1 / A1 / T1 / D1 : Use a pair of TP-Link MC110CS (Note: old hardware revisions of MC210CS is not compatible)

Between the pair of FMC you need a single mode SC-SC duplex fiber (note: SC-SC is for a pair of FMC, not for SFP):

The Lumin-side FMC needs to be driven by a LPS, an inexpensive one is:
