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.
