Figure 2: UPM card LEDs and connectors
Single-mode or multi-mode fiber-optic cables attach to UPM cards through small
form factor pluggable (SFP) optic transceivers. The fiber-optic transceivers
provide duplex connectors, and can be detached from UPM cards (through a
10-pin interface) for easy replacement. Three fiber-optic transceiver types are
available:
■
Short-wave Laser—Short-wave laser transceivers provide connections for
transferring data over short distances (2 to 500 meters) through 50-µm (500
meters) or 62.5-µm (200 meters) multi-mode fiber.
Note:
Hewlett-Packard recommends 50-µm fiber-optic cable for any new
installation requiring multi-mode fiber.
■
Long-wave Laser—Long-wave laser transceivers provide connections for
transferring data over long distances (up to 10 kilometers) through 9-µm
single-mode fiber.
