35
MBd or 25 MHz (mega Hertz) – High speed, low
noise, photodiode coupled to a TIA (transimpedance amplifier)
which produces an output voltage proportional to the
input light amplitude. This hybrid approach solves many
of the problems of high-speed data link designs by placing
a pre-amplifier close to the photodiode. The level amplification
produced by the transimpedance amplifier makes the output
signal much less susceptible to interference which is
a problem often found at high data rates and in high
EMI environments. This product is available as a component
or connectorized and actively aligned for optimal use
with multimode fiber optic cables.
125MBd
or 100MHz – Transceiver module designed with
a low cost 850nm alternative to expensive 1300nm FDDI
and ATM components. FDDI and ATM compliant signaling
allows the system designer to design short haul FDDI
and ATM performance with a significant cost savings.
This product is supplied in the industry standard 1X9
SIP package with a duplex EC connector.
155MBd
or 125MHz – The receiver is comprised of a
high speed, low noise photodiode coupled to a transimpedance
amplifier that produces an output voltage proportional
to the input light amplitude. This hybrid approach solves
many of the problems of high-speed data link designs
by placing a pre-amplifier close to the photodiode. The
level amplification produced by the transimpedance amplifier
makes the output signal much less susceptible to interference
which is a problem often found at high data rates and
in high EMI environments. The output of the receiver
is an analog low impedance, emitter follower voltage
source capable of driving an amplifier or level translating
circuitry. This allows the subsequent circuitry to use
the device in either the analog mode or translated to
ECL\TTL levels for use in a digital circuit. This product
is available as a component or connectorized and actively
aligned for optimal use with multimode fiber optic cables.
The transceiver is assembled in a SFF (small form factor) package
for use in data communications applications utilizing an MT-RJ dual
fiber receptacle designed for high density implementations and easy
end-user installation. The transmitter is an 850nm LED and is configured
for optimum performance when used in conjunction with an integrated
receiver. The receiver consists of a high speed PIN photodiode coupled
with a low noise transimpedance amplifier (TIA). The receiver output
is a NRZ (non return to zero) low impedance analog source designed
to be easily converted to PECL or TTL levels by external circuitry.
This combination of devices and packaging result in a physical layer
medium dependent (PMD) sub-layer for communications between nodes
of a fiber network.
The transceiver assembled in the 1X9 Form Factor Duplex SC or ST
Connector package is designed for use in 100Base-FX, ATM, SONET and
FDDI PMD markets. This configuration utilizes a 1310nm LED and receiver.
The characterization is performed in accordance with the FDDI PMD
standard, and the Fast Ethernet Alliance defines the physical layer
for 100 Base-FX. The design consists of a transmitter optical subassembly,
a receiver optical subassembly, and an electrical sub-assembly. They
are all in the same package utilizing either a +5 volt or +3.3 volt
power supply. The input driver circuit converts the differential
PECL signals into a proportional light signal to be transmitted at
1300nm through a multimode fiber optic cable. The receiver optical
sub-assembly consists of an InGAAs PIN photodiode and transimpedance
amplifier in an integrated package to optimize performance. The resulting
analog output is coupled to a post-amplifier for signal conditioning
and conversion to differential, PECL high-speed electrical outputs.
