DESCRIPTION

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.

The Siemens Gigabit Ethernet multimode transceiver—part of

Siemens Small Form Factor transceiver family—is based on the

Physical Medium Depend (PMD) sublayer and baseband

medium, type 1000BASE-SX (short wavelength).

The appropriate fiber optic cable is 62.5 µm or 50 µm multimode

fiber with VF-45 (Volition™) connector.

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 Siemens Gigabit Ethernet multimode transceiver is a single

unit comprised of a transmitter, a receiver, and an VF-45 recepta-

cle. This design frees the customer from many alignment and PC

board layout concerns.

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 140 milliseconds after

the voltage has risen above the reset threshold. During this

time the laser is inactive.

This transceiver supports the innovative Volition connectorization

concept, which competes with UTP/CAT 5 solutions. It is com-

patible with RJ-45 style backpanels for fiber-to-the-desktop appli-

cations while providing the advantages of fiber optic technology.

The receptacle accepts the new SG connector. The Small Form

Factor is specially developed for distances of up to 550 m.

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.

LASER SAFETY

Receiver

Symbol Min. Typ. Max. Units

This multimode Gigabit Ethernet transceiver is a Class 1 laser

product. It complies with IEC 825-1 and FDA 21 CFR 1040.10

and 1040.11. The transceiver must be operated under recom-

mended operating conditions. Because the transceiver design

is designed to be inhevently eye safe, it does not require open

fiber control thus eliminating complex electronics or mechanics.

General Restrictions

Classification is valid only if the module is operated within the

specified temperature and voltage limits. The system using the

module must provide power supply protection that guarantees

that the system power source will cease to provide power if the

maximum recommended operation limit or more is detected on

the +3.3 V at the power source. The case temperature of the

module must be in the temperature range given in the recom-

mended operating limits. These limits guarantee the laser

safety.

Notes

Note

1. Minimum average optical power at which the BER is less than

1 x 10E–12. Measured with a 2⁷–1 NRZ PRBS and ER=9 dB.

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)).

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.
