TXN17431 (0850) Optical Transceiver
Introduction
The Intel
Transceiver compliant with the XENPAK Multisource Agreement (MSA). The TXN17431
Optical Transceiver provides an IEEE 802.3ae 2002-compliant 10GBASE-SR interface
between the photonic physical layer and the electrical section layer.
The TXN17431 Optical Transceiver is comprised of an optical transmitter and receiver
pair integrated with XAUI-to-serial conversion. PCS, PMA, and PMD functions are
included.
Unless otherwise noted, the Intel
Transceiver Compliant with XENPAK MSA will be called the TXN17431 Optical
Transceiver throughout the remainder of this document.
The TXN17431 Optical Transceiver transmitter section decodes four 8B/10B-encoded
channels running at 3.125 Gbps for Ethernet from a XAUI parallel data bus, performs a
64B/66B scrambling and multiplexes the results into a 10.3125 Gbps optical signal
launched into a multi-mode optical fibre using an 850 nm Vertical Cavity Surface
Emitting Laser (VCSEL).
The TXN17431 Optical Transceiver receiver section de-multiplexes a single 10.3 Gbps
(Ethernet) optical signal and converts it back to four channels of 3.125 Mbps (Ethernet)
XAUI. The receiver includes a photodiode, transimpedance amplifier, clock recovery,
decision circuit, and de-multiplexer. The receiver operates over an 850 nm band for
10GBASE-SR.

The TXN17431 Optical Transceiver is assembled in a XENPAK MSA-compatible 4.8 in. L
× 1.4 in. W × 0.7 in. H package. The heat sink is designed for a 50 °C ambient
temperature with 200 linear feet-per-minute airflow. A XENPAK MSA-compliant, 70-pin,
board edge connector provides/supplies the electrical interface. Optical connections are
made with standard SC-UPC optical connectors.
The TXN17431 Optical Transceiver is designed for link spans up to 300 m and uses an
850 nm Transistor Outline (TO)-can laser source.
An IEEE 802.3ae version 5 and XENPAK MSA-compliant Management Data Interface
(MDIO) with Digital Optical Monitoring (DOM) support is included.
