Agilent HFCT-5915E Characterization
Report for MT-RJ Duplex Single Mode
Transceiver
Application Note 1209
Introduction
The HFCT-5915E transceiver is a
high performance, cost effective
module for serial optical data
communication applications
specified for a signal rate of
155 Mb/s. It is designed to provide
an ATM/SONET/SDH compliant
link for 155 Mb/s long reach
applications over 0°C to +70°C
temperature range. The module is
intended for single mode fiber,
operates at a nominal wavelength
of 1300 nm and is packaged in an
industry standard 2 x 5 platform.
It incorporates Agilent’s high
performance, reliable, long
wavelength optical devices and
proven circuit technology to give
long life and consistent service.
The characterization was
performed in accordance with
Bellcore Specification
TA-NWT-000983.
Summary
• The characterization
demonstrates that the
HFCT-5915E complies with the
Product Specification
• HFCT-5915E - SONET OC3 SDH
STM-1 Compliant
This report evaluates the
HFCT-5915E transmitter
performance under all conditions
against target parameters in the
Product Specification.
The HFCT-5915E receiver
characterization has been
completed by claimed similarity
with the HFCT-5905E, due to
common optical subassembly,
electrical assembly and package
style. The results of the HFCT-
5905E receiver characterization
are included here from
Application Note 1181 for
completeness.
The following transmitter
parameters were characterized at
3.1 V, 3.3 V and 3.5 V at 0°C, +25°C
and +70°C:
• Output Power
• Extinction Ratio
• Transmitter Supply Current
• Wavelength
• Spectral Width
• Eye Mask
SONET/SDH compliant eye
diagrams are also presented.
Definition of terms
Transmitter Parameters
Output Power (dBm)
The optical output power is an
averaged measurement using a
1 m MT-RJ patchcord terminated
with an SC connector into a large
area detector. This measurement
allows for the loss of the MT-RJ
Connector. The module was
modulated at 155.52 Mb/s using a
2E23-1 PRBS data pattern .
Extinction Ratio (dB)
This is the ratio of optical power
in a “1” or “on” logic state to the
optical power in a “0” or “off” logic
state. The Extinction Ratio is
measured using a 1010... data
pattern at 50 MHz. This gives a flat
top and bottom to the output
pulse in order to make accurate
measurements.
Transmitter Supply Current (mA)
This is the current supplied to the
transmitter at the relevant supply
voltage including that drawn by
the test fixture but excluding that
drawn by the termination
resistance network.

Receiver and Transmitter power
supply noise immunity
Using the MSA power supply filter
shown in Figure 1, noise of
varying amplitude and frequency
was injected onto the Rx VCC and
receiver sensitivity monitored.
The worst case receiver noise
immunity observed was 200 mV
pk-pk for 1 dB degradation in
sensitivity.
The transmitter worst case
immunity occurred at 1 MHz. At
this frequency a 164 mV pk-pk
sinusoid signal on the VCC rail
reduces the data output eye mask
margin to 20%.
Figure 2 shows the transmitter’s
noise rejection performance as a
function of frequency.
