STM-16 Fiberhome Fonsweaver 780b 0.765 Kg Supports All Soh Bytes
The O2500 card is used as a line card in the system to implement the access and processing of one STM-16 optical interface service.
Provides one STM-16 optical interface.
Supports transparent transmission of overheads.
Supports the test on performance such as optical power, laser bias current and bit error.
Performs the multiplexing and demultiplexing of the signal.
Supports the SOH processing and supports all the defined SOH bytes (such as A1, A2, J0, B1, B2, S1, M1, H1, H2, H3, E1, E2, F1, D1 to D12, K1 and K2).
Supports monitoring of the higher order path overheads (such as J1, B3, C2 and G1).
Supports the equipment loopback and line loopback tests.
Supports the seamless switch between the active and standby clock and crossconnect cards.
Supports hot insertion at the optical interface.
Supports the automatic shutdown of the laser.
Supports the remote software upgrade.
The working principle of the O2500 card is shown as below.
