DESCRIPTION
The Siemens single mode transceiver is based on the Physical
Medium Depend (PMD) sublayer and baseband medium, type
1000BASE-LX (Long Wavelength Laser).
The appropriate fiber optic cable is 9 µm (mode field diameter)
single mode fiber (up to 10 km) with Duplex SC connector.
The Siemens single mode transceiver is a single unit comprised
of a transmitter, a receiver, and an SC receptacle. This design
frees the customer from many alignment and PC board layout
concerns. The module is designed for low cost LAN, WAN and
Gigabit Ethernet applications. It can be used as the network
end device interface in mainframes, workstations, servers, and
storage devices, and in a broad range of network devices such
as bridges, routers, intelligent hubs, and local and wide area
switches.
This transceiver operates at 1.3 Gbits per second from a single
power supply (+5 Volt or 3.3 Volt). The full differential data
inputs and outputs are PECL compatible.
Functional Description of 1x9 Pin Row Transceiver
This transceiver is designed to transmit serial data via single
mode cable.
Functional Diagram
The receiver component converts the optical serial data into
PECL compatible electrical data (RD and RDnot). The Signal
Detect (SD, active high) shows whether an optical signal
is present.
The transmitter converts electrical PECL compatible serial data
(TD and TDnot) into optical serial data.
1. AC/DC Transceiver
Tx is AC coupled. Differential 100 Ω load. Rx has standard PECL
output and is DC coupled.
2. AC/AC TTL Transceiver
Tx and Rx are AC coupled. Tx has differential 100 Ω load. Signal
Detect is TTL compatible.
3. DC/DC Transceiver
Standard PECL inputs and outputs Tx and Rx are DC coupled.
4. AC/AC PECL Transceiver
Tx and Rx are AC coupled. Tx has differential 100 Ω load. Signal
Detect is PECL compatible.
The transmitter contains a laser driver circuit that drives the
modulation and bias current of the laser diode. The currents are
controlled by a power control circuit to guarantee constant out-
put power of the laser over temperature and aging. The power
control uses the output of the monitor PIN diode (mechanically
built into the laser coupling unit) as a controlling signal, to pre-
vent the laser power from exceeding the operating limits.
Single fault condition is ensured by means of an integrated
automatic shutdown circuit that disables the laser when it
detects transmitter failures. A reset is only possible by turning
the power off, and then on again.
The transceiver contains a supervisory circuit to control the
power supply. This circuit makes an internal reset signal when-
ever the supply voltage drops below the reset threshold. It
keeps the reset signal active for at least 15 milliseconds after
the voltage has risen above the reset threshold. During this
time the laser is inactive.

Transmitter Electro-Optical Characteristics
Notes
1. Into single mode fiber, 9 µm diameter.
2. Laser power is shut down if power supply is below VTH and
switched on if power supply is above VTH after tRES.
Receiver Electro-Optical Characteristics
Notes
1. Minimum average optical power at which the BER is less than
1x10E-12 or lower. Measured with a 27-1 NRZ PRBS and ER=9 dB.
2. An increase in optical power above the specified level will cause the
SIGNAL DETECT output to switch from a Low state to a High state.
3. A decrease in optical power below the specified level will cause the
SIGNAL DETECT to change from a High state to a Low state.
4. DC/DC, AC/DC for data
DC/DC, AC/DC, AC/AC PECL for Signal Detect
PECL compatible. Load is 50 Ω into VCC –2 V for data, 500 Ω to V
((
for Signal Detect. Measured under DC conditions. For dynamic mea-
surements a tolerance of 50 mV should be added. VCC=3.3 V/5 V.
5. Max. output current high: –0.4 mA (drive current)
low: +2.0 mA (sink current)
6. AC/AC for data. Load 50 Ω to GND or 100 Ω differential. For dynamic
measurement a tolerance of 50mV should be added.
LASER SAFETY
This single mode transceiver is a Class 1 laser product. It
complies with IEC 825-1 and FDA 21 CFR 1040.10 and 1040.11.
To meet laser safety requirements the transceiver shall be oper-
ated within the maximum ratings.
Caution
The use of optical instruments with this product will
increase eye hazard!
Usage Restrictions
The optical ports of the modules must be terminated with an
optical connector or with a dust plug.
Note
Failure to adhere to the above restrictions could result in a modifica-
tion that is considered an act of “manufacturing,” and will require,
under law, recertification of the modified product with the U.S. Food
and Drug Administration (ref. 21 CFR 1040.10 (i)).
