The OPC board is an optical-layer platform board that must work with pluggable modules.
When the SNCP ring consisting of four Optis OSN 2500 devices has a rate of 25 Gbt/s, the network's service answer stars can carry up to ()2Mt/s Signal.
When using the LCAS function, which of the following overhead bytes is used to transmit control information? (Multiple Choices)
Establish Ethernet leased line service between HI (HQ) and H2 (branch) of enterprise H, and bind 5 in the corresponding VCTRUNK VC-12. When a VC-12 fails, the Ethernet dedicated line between H1 and H2 is interrupted. So, which of the following statements is true?
A light wave has two independent and orthogonally polarized modes on the plane perpendicular to the transmission direction, which are generally called X polarization and Y polarization respectively. Using this property of optical signals, the polarization multiplexing separately modulates optical signals on the two orthogonal polarizations.
