The ST2 board is mainly used to process and regenerate optical
supervisory signals. In addition, the ST2 board supports the IEEE
1588v2 function. In addition, the TN12ST2 board supports line fiber
quality monitoring.
For detailed functions and features, refer to Table 1.
Table 1 Functions and features of the ST2 board
Function and Feature
Description
Basic function
Receives, processes, and transmits two optical supervisory signals.
Supports transparent transmission of two channels of FE electrical
signals.
Supports IEEE 1588v2 function.
Supports physical clock function.
Supports a maximum of 40.5 dB transmission.
NOTE:
When the ST2 board is used in an OptiX OSN 8800 universal platform
subrack, the board can transparently transmit IEEE 1588v2 clock and
physical clock signals, but the board cannot process IEEE 1588v2
clock and physical clock signals.
Technical features
The OSC has no limitation on the distance between two optical line
amplifiers. The failure of an optical line amplifier does not
affect the performance of the OSC.
The ST2 board is independent of the SCC. When the SCC is not
properly installed, the ST2 board can still ensure the pass-through
of ECC with the two optical interfaces and monitor other stations.
Regeneration function
The ST2 board transmits signals from section to section. It also
has the 3R function. In each regenerating station that has optical
amplifiers, information can be correctly received and new
supervisory signals are added.
Operating wavelength
When the ST2 board works with the SFIU board, the signal
wavelengths of supervisory channel for RM1/TM1 is 1511 nm, and the
signal wavelengths of supervisory channel for RM2/TM2 is 1491 nm.
When the ST2 board works with the FIU board, the supervisory
channel signal wavelength is 1511 nm.
Loopback
Supports outloops.
Optical-layer ASON
Supported
Line fiber quality monitoring
The line fiber quality monitoring function can be used on the NMS,
and the NMS will display monitoring figures and data. The online
and offline applications of line fiber quality monitoring are
supported. For details, see the Fiber Doctor System in the Feature Description.
The Fiber Doctor Management System Software Fee License needs to be purchased for this function.
eSFP
The board supports pluggable optical modules that use 1511 nm and
1491 nm wavelengths.
