The
HFBR-5301
is a 1300 nm
transceiver specified for use in
133 MBd, 12.5 MB/s, 12-M6-LE-I
Fibre Channel interfaces to either
62.5/125
µm
or 50/125
µm
multimode fiber-optic cables.
The
HFBR-5302
is a 1300 nm
transceiver specified for use in
266 MBd, 25 MB/s, 25-M6-LE-I
Fibre Channel interfaces to either
62.5/125
µm
or 50/125
µm
multimode fiber-optic cables.
Applications
• Fibre Channel 12.5 MB/s
12-M6-LE-I Interfaces for
1300 nm LED Links to
1500 m
• Fibre Channel 25 MB/s
25-M6-LE-I Interfaces for
1300 nm LED Links to
1500 m
These are packaged in the optical
subassembly portion of the
receiver.
These PIN/preamplifier combina-
tions are coupled to a custom
quantizer IC which provides the
final pulse shaping for the logic
output and the Signal Detect
function. The Data output is
differential. The Signal Detect
output is single-ended. Both data
and signal detect outputs are
PECL compatible, ECL refer-
enced (shifted) to a +5 volt
power supply.
Transmitter Sections
The transmitter sections of the
HFBR-5301 and HFBR-5302
utilize 1300 nm InGaAsP LEDs.
These LEDs are packaged in the
optical subassembly portion of
the transmitter section. They are
driven by a custom silicon IC
which converts PECL logic
signals, into an analog LED drive
current.
Description
The HFBR-5301 and HFBR-5302
Fibre Channel Transceivers from
Hewlett-Packard provide the
system designer with products to
implement Fibre Channel designs
for use in multimode fiber (MMF)
applications. These include the
12.5 MB/sec 12-M6-LE-I interface
and the 25 MB/sec 25-M6-LE-I
interface for 1300 nm LED links.
Package
The overall package concept for
the HP Fibre Channel trans-
ceivers consists of three basic
elements; the two optical
subassemblies, an electrical
subassembly and the housing
with integral duplex SC connec-
tor interface. This is illustrated in
the block diagram in Figure 1.

Receiver Sections
The receiver sections of the
HFBR-5301 and HFBR-5302
utilize InGaAs PIN photo diodes
coupled to a custom silicon
transimpedance preamplifier IC.
