Description
The HFBR-1116TZ/-2116TZ series of data links are
high-performance, cost-efficient, transmitter and
receiver modules for serial optical data communication
applications specified at 155 MBd for ATM UNI
applications.
These modules are designed for 50 or 62.5
m 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 subassembly.
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.
