DESCRIPTION
The Siemens multimode transceiver is based on the Physical
Medium Depend (PMD) sublayer and baseband medium, type
1000BASE-SX (Long Wavelength Laser) (IEEE 802.5) and
complies with the Fibre Channel Physical and Signaling
Interface (FC-PH), ANSI XSI TT Fibre Channel Physical Standard
Class 100-M5-SLI, latest Revision.
The appropriate fiber optic cable is 62.5 μm or 50 μm multi-
mode fiber with Duplex SC connector.
The Siemens multimode 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, Gigabit Ether-
net, and Fibre Channel applications. It can be used as the net-
work 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 1.0625 Gbit/s and 1.3 Gbit/s 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
This transceiver is designed to transmit serial data via multi-
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.
The following versions are avaible:
1. AC/DC Transceiver
Tx is AC coupled. Differential 100
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
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
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 generates an internal reset signal
whenever 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.
