Does a secondary distribution box include a power meter

Closer to the customer, a distribution transformer steps the primary distribution power down to a low-voltage secondary circuit, usually 120/240 V in the US for residential customers. The power comes to the customer via a service drop and an electricity meter. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers.

Is the optical power meter multimode or single-mode

Optical power meters can measure the power of both single-mode and multimode fibers. In single-mode fiber, the rays travel down its entire length without any internal reflection at all.
