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.
SAN High Availability Planning Guide
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.
