Director 2/140 The director is configured from a minimum of 16 universal
port module (UPM) cards (64 ports total) to a maximum of 35 UPM cards
(140 ports total).
UPM cards provide four 2.125 Gbps port connections and can be configured
with shortwave transceivers, longwave transceivers, and extended longwave
transceivers or a combination of all three.
Edge Switch 2/12 The switch provides up to 12 duplex SFP fiber-optic
port transceivers (2.125 Gbps operation only). Shortwave laser, longwave
laser, and extended longwave transceivers are available.
Edge Switch 2/16 The switch provides up to 16 duplex small form factor
pluggable (SFP) fiber-optic port transceivers (2.125 Gbps operation only).
Shortwave laser, longwave laser, and extended longwave transceivers are
available.
Edge Switch 2/24 The switch provides up to 24 duplex SFP fiber-optic
port transceivers (2.125 Gbps operation only). Shortwave laser, longwave
laser, and extended longwave transceivers are available.
Edge Switch 2/32 The switch provides up to 32 duplex SFP fiber-optic
port transceivers (2.125 Gbps operation only). Shortwave laser, longwave
laser, and extended longwave transceivers are available.
Optical Transceivers
Shortwave optical transceivers provide a connection for multimode cable with a
core diameter of 50 microns and a cladding diameter of 125 microns (50/125) or
multimode cable with a core diameter of 62.50 microns and a cladding diameter
of 125 microns (62.5/125). A 50/125 micron cable allows a maximum
switch-to-device or switch-to-switch distance of up to 300 meters at a 2.125 Gbps
data transmission speed. A 62.5/125 micron cable allows a maximum
switch-to-device or switch-to-switch distance of up to 150 meters at a 2.125 Gbps
data transmission speed.
A 62.5 micron cable is supported only for the use of existing cable plants. HP
recommends the use of 50 micron cables for new installations.
Longwave optical transceivers provide a connection for single-mode cable with a
core diameter of 9 microns and a cladding diameter of 125 microns (9/125).
Depending on transceiver type, a 9/125 micron cable allows switch-to-device or
switch-to-switch distances of 10, 20, or 35 kilometers.
HP supplies cables for 10 and 35 kilometers. For longer distances, you need Fibre
Channel repeaters or wave division multiplexing (WDM) devices.
