The 5833P diplexer is a single-fiber transceiver that enables
simultaneous bi-directional, voice and data transport over a single fiber
in FTTx (access) networks.
The diplexer consists of a Fabry-Perot laser and a PIN photodiode
coupled to a PECL interface for easy installation.
These low-cost devices can be used in a variety of locations in the
network where single-fiber telemetry is required. The laser emits 1310
nm, and the photodetector receives another 1310 nm signal.
Applications
Single-fiber data and voice
transport
FTTx architectures
Site-to-site optical telemetry
Customer-premise gateways
The 5833P diplexer is currently available at OC-3 (155 Mbits/s) and OC-
12 (622 Mbits/s) data rates and with several optical connector options.

Absolute Maximum Ratings
DATA SHEET| JULY 24, 2003
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in
excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.

Electrostatic Discharge
Caution: This device is susceptible to damage as a result of electrostatic discharge (ESD). Take proper
precautions during both handling and testing. Follow EIA® Standard EIA-625.
Although protection circuitry is designed into the device, take proper precautions to avoid exposure to ESD.
Ortel, a division of EMCORE, employs as a human-body model (HBM) for ESD susceptibility testing and
protection-design evaluation. ESD voltage thresholds are dependent on the critical parameters used to define
the model. A standard HBM (resistance = 1.5 kΩ, capacitance = 100 pF) is widely used and, therefore, can be
used for comparison purposes. The HBM ESD threshold established for the 5833P transceiver is
±
2000 V.
Transciever Processing
When the process plug is placed in the transceiver’s optical port, the transceiver and plug can withstand normal
wave soldering and aqueous spray cleaning processes. However, the transceiver in not hermetic and should
not be immersed in cleaning solvents. The transceiver case should not be exposed to temperatures in excess of
125°C. The transceiver pins can be wave soldered at 240°C for up to 10 seconds. The process plug should only
be used once. After removing the process plug from the transceiver, it must not be used again as a process
plug; however, if it has not been contaminated, it can be reused as a dust cover.

Printed-Wiring Board Layout Considerations
A fiber-optic receiver employs a very high gain, wide bandwidth transimpedance amplifier. This amplifier detects
and amplifies signals that are only tens of nA in amplitude when the receiver is operating near its sensitivity
limit. Any unwanted signal currents that couple into the receiver circuitry cause a decrease in the receivers
sensitivity and can also degrade the performance of the receiver’s signal-detect (SD) circuit. To minimize the
coupling of unwanted noise into the receiver, careful attention must be given to the printed circuit board.
At a minimum, a double-sided printed-wiring board (PWB) with a large component-side ground plane beneath
the transceiver must be used. In applications that include many other high-speed devices, a multi-layer PWB is
highly recommended.
This permits the placement of power and ground on separate layers, which allows them to be isolated from the
signal lines.
Multi-layer construction also permits the routing of sensitive signal traces away from high-level, high-speed
lines. To minimize the possibility of coupling noise into the receiver section, high-level, high-speed signals such
as transmitter inputs and clock lines should be routed as far away as possible from the receiver pins.
Noise that couples into the receiver through the power supply pins can also degrade performance. It is
recommended that a pi filter be used for both transmitter and receiver supplies.
