Function and Feature
Description
Basic functions
Transmits and receives 2xSTM-64 FEC optical signals.
Supports configuration of the normal FEC or enhanced FEC function.
Specifications of the optical interface
Supports different types of standard optical interfaces, namely,
the Ue-64.2c, Ue-64.2d, and Ue-64.2e. The characteristics of the
optical interfaces comply with the standards defined by .
Supports the output of the standard DWDM wavelengths that comply
with ITU-T G.692 and can be directly connected to the WDM
equipment.
Specifications of the optical module
Supports XFP pluggable optical modules.
Supports the detection and query of information about the optical
module.
Provides the ALS function. The optical interface supports the
setting of the on/off state of a laser.
Service processing
Supports the VC-12 services, VC-3 services, VC-4 services, VC-4-4c
concatenation services, VC-4-16c concatenation services, and
VC-4-64c concatenation services.
SDH Clock Synchronization
Supported.
Overhead processing
Processes the section overheads of the STM-64 signals.
Supports the transparent transmission and termination of the path
overheads.
Supports the setting and query of the J0, J1, and C2 bytes.
Supports two channels of ECC communication.
Supports HWECC (default), IP, or OSI protocol stacks.
Supports the 1.5 Mbit/s DCN.
Alarms and performance events
Reports various alarms and performance events.
Protection schemes
Supports the two-fiber ring MSP.
Supports the four-fiber ring MSP.
Supports the linear MSP.
Supports the SNCP.
Supports the SNCTP.
Supports the fiber-shared virtual trail protection.
Supports the fiber-shared MSP.
Supports the transoceanic MSP ring.
NOTE:
Supports processes four sets of K bytes. A single optical interface
can process two sets of K bytes. One SFD64 board supports a maximum
of four MSP rings.
Maintenance features
Supports inloops and outloops at optical interfaces.
Supports inloops and outloops on VC-4 paths.
Supports the function of automatically releasing service loopbacks
after the specified time expires.
Supports warm resets and cold resets. The warm reset does not
affect services.
Supports the query of the manufacturing information of the board.
Supports the in-service loading of the FPGA.
Supports the upgrade of the board software without affecting
services.
Supports the PRBS function.
Supports the press-to-collect function in fault data collection.

SFD64 Specifications
Specifications include optical specifications, laser safety class,
mechanical specifications, and power consumption.
Optical Specifications
Table 1 lists the optical specifications of the SFD64 board.
a: The numbers in the brackets indicate the corresponding parameter
values. For example, "OBU101 (-28 dBm to -31 dBm)" indicates that
the optical power amplified by the OBU101 is -28 dBm to -31 dBm.
b: "OBU101 + OAU103" indicates that the specifications of the
optical interface are measured when the OBU101 and OAU103 are used.
c: The parameters are only for the optical modules. The parameters
of the amplifier are not provided.
