Description
The Infineon OC-12 transceiver part of Infineon iSFPTM family is compatible to the
Physical Medium Depend (PMD) sublayer and baseband medium compatible to SONET
OC-12/OC-3 IR-1 (Telcordia GR-253-CORE) and SDH STM-4 S-4.1/S-1.1 (ITU-T
G.957).
The appropriate fiber optic cable is 9 m single mode fiber with LCTM connector.
The Infineon iSFPTM single mode transceiver is a single unit comprised of a transmitter,
a receiver, and an LCTM receptacle.
This transceiver supports the LCTM connectorization concept. It is compatible with RJ-45
style backpanels for high end datacom and telecom applications while providing the
advantages of fiber optic technology.
The Infineon single mode OC-12 transceiver is a single unit comprised of a transmitter,
a receiver, and an LC receptacle. This design frees the customer from many alignment
and PC board layout concerns. The module is designed for low cost LAN and
applications with datarates from 125 to 622 Mbit/s. It can be used as the network end
device interface in workstations, servers, and storage devices, and in a broad range of
network devices such as bridges, routers, and intelligent hubs, as well as local and wide
area ATM switches.
This transceiver operates at up to OC-12 datarates from a single power supply (+3.3 V).
The 100
differential data inputs and outputs are LVPECL and CML compatible.

Functional Description of iSFPTM Transceiver
This transceiver is designed to transmit serial data via single mode cable.
Figure 2
Functional Diagram
The receiver component converts the optical serial data into CML compatible electrical
data (RD+ and RD). The Loss Of Signal (LOS) shows whether an optical signal is
present.
The transmitter converts CML compatible electrical serial data (TD+ and TD) into
optical serial data. Data lines are differentially 100
terminated.
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 output 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 prevent 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 laser fault to guarantee the laser Eye Safety.
