Description
The HFBR-1119/-2119 series of
data links are high-performance,
cost-efficient, transmitter and
receiver modules for serial
optical data communication
applications specified at 266 MBd
for Fibre Channel applications or
for general-purpose fiber optic
data link transmission.
These modules are designed for
50 or 62.5 µm core multimode
optical fiber and operate at a
nominal wavelength of 1300 nm.
They incorporate our high-
performance, reliable, long-
wavelength, optical devices and
proven circuit technology to give
long life and consistent
performance.
Transmitter
The transmitter utilizes a 1300 nm
surface-emitting InGaAsP LED,
packaged in an optical subassem-
bly. The LED is dc-coupled to a
custom IC which converts
differential-input, PECL logic
signals, ECL-referenced (shifted)
to a +5 V power supply, into an
analog LED drive current.
Receiver
The receiver utilizes an InGaAs
PIN photodiode coupled to a
custom silicon transimpedance
preamplifier IC. The PIN-
preamplifier combination is ac-
coupled to a custom quantizer IC
which provides the final pulse
shaping for the logic output and
the Signal Detect function. Both
the Data and Signal Detect
Outputs are differential. Also,
both Data and Signal Detect
Outputs are PECL compatible,
ECL-referenced (shifted) to a
+5 V power supply.
Package
The overall package concept for
the Data Links consists of the
following basic elements: two
optical subassemblies, two
electrical subassemblies, and the
outer housings as illustrated in
Figure 1.
