Description
The HFBR-53A5VM transceivers
from Agilent Technologies allow the
system designer to implement a
range of solutions for multimode
Gigabit Ethernet applications.
The overall Agilent transceiver
product consists of three sections:
the transmitter and receiver optical
subassemblies, an electrical
subassembly, and the package
housing which incorporates a
duplex SC connector receptacle.
Transmitter Section
The transmitter section of the
HFBR-53A5VEM/FM consists of an
850 nm Vertical Cavity Surface
Emitting Laser (VCSEL) in an
optical subassembly (OSA), which
mates to the fiber cable. The OSA is
driven by a custom, silicon bipolar
IC which converts differential PECL
compatible logic signals into an
analog laser diode drive current.
The high speed output lines are
internally ac-coupled and
differentially terminate with a 100
鈩?/div>
resistor.
Receiver Section
The receiver of the
HFBR-53A5VEM/FM includes a
GaAs PIN photo-diode mounted
together with a custom, silicon
bipolar transimpedance
preamplifier IC in an OSA. This
OSA is mated to a custom silicon
bipolar circuit that provides post-
amplification and quantization.
The post-amplifier also includes a
Signal Detect circuit which pro-
vides a TTL logic-high output
upon detection of a usable input
optical signal level. The high
speed output lines are internally
ac-coupled.
