• Transceiver Type - The installed transceiver type (SFP or
Unknown).
If the port has a digital diagnostics (DD) enabled optical transceiver
installed, product firmware displays a table of reported temperature,
voltage, current, transceiver power, and receiver power. Optical
transceivers also provide vendor-specific threshold values for these
parameters.

At the Port List View, click the entry for a port in the Transceiver
column. Port transceiver technology information for the selected port
appears in the lower panel of the view:
• Port Number - The director port number.
• Identifier - Installed transceiver type (SFP or Unknown).
• Connector type - The type of port connector (LC, MT_RJ, MU,
Unknown, or Internal Port).
• Transceiver - The type of port transceiver (Shortwave Laser,
Longwave Laser, Long Distance Laser, Unknown, or None).
• Distance Capability - The port transmission distance (Short,
Intermediate, Long, Very Long, or Unknown).
• Media - The type of optical cable used (Singlemode, multimode
50-micron, multimode 62.5-micron, or Unknown).
• Speed - The operating speed of the port (Not Established, 1 Gbps, 2
Gbps, or 10 Gbps (with XPM)).
The EFCM Basic Edition interface provides access to port statistics
information through the Performance View. To open this view, select
Performance from the Product menu at any other view. The following
statistical information appears:
• Traffic Statistics - These statistics include port transmit and
receive values for frames; four-byte words; offline sequences; link
resets; and link utilization percentage. The time spent using no
transmission buffer-to-buffer credit (BB_Credit) is also reported.
• Error Statistics - These statistics include the number of link
failures; synchronization and signal losses; discarded frames;
invalid transmission words; primitive sequence, cyclic
redundancy check (CRC), delimiter, and address identification
errors; and short frames.
