Field Description
transceiver information Transceiver information
Transceiver Type Transceiver type
Connector Type
Type of the connectors of the transceiver:
• SC—Fiber connector, developed by NTT
• LC—1.25 mm/RJ-45 optical connector developed by Lucent.
• RJ-45
• CX 4
Wavelength(nm)
• Fiber transceiver—Central wavelength (in nm) of the laser sent. If the
transceiver module supports multiple wavelengths, every two wavelength
values are separated by a comma.
• Copper cable—Displayed as N/A.
Transfer distance(xx)
Transfer distance, where "xx" represents the distance unit: km (kilometers) for
single-mode transceivers and m (meters) for other transceivers.
If the transceiver supports multiple transfer medium, every two values of the
transfer distance are separated by a comma. The transfer medium is included in
the bracket following the transfer distance value. The following are the transfer
media:
• 9 um—9/125 μm single-mode optical fiber
• 50 um—50/125 μm multi-mode optical fiber
• 62.5 um—62.5/125 μm multi-mode optical fiber
• TP—Twisted pair
• CX4—CX4 cable
Digital Diagnostic
Monitoring
Support for the digital diagnosis function:
• YES—Supported
• NO—Not supported
