(1) Optical path service: the optical path service refers to a channel provided by the communication optical cable network; the optical path service starts from the user equipment port (starting point) and ends at the user equipment port (ending point), and the path hops fiber and the fiber core of the optical cable.
As shown in fig. 7, a light path service has a start point of a user equipment a/P2 and an end point of a user equipment B/P5; the optical fiber is jumped by the path (user equipment A/P2-optical fiber distribution frames A/P6 and P7), the optical cable (A-B) 6 th core and 7 th core, and the optical fiber is jumped by the path (user equipment B/P5-optical fiber distribution frames B/P6 and P7).
(2) Transmission service: the transmission service refers to a channel provided by a transmission system; the transmission traffic starts from the user equipment port (starting point) and ends at the user equipment port (ending point), and the network element and the link (time slot) are transmitted by the path.
