Data Sheet
Description
The HFBR-1115TZ/-2115TZ series of data links are high-
performance, cost-efficient, transmitter and receiver
modules for serial optical data communication applica-
tions specified at 100 Mbps for FDDI PMD or 100 Base-FX
Fast Ethernet applications.
These modules are designed for 50 or 62.5 μm core multi-
mode 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 perfor-
mance.
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.
