Molex Develops Small Form Factor 10Gigabit Solution
Transponder, guide system and connector compliant with XPAK MSA, enables l0Gig in space constrained applications.
INTEL DEVELOPER FORUM, San Jose, CA - September 9, 2002 -- Molex announced today that it has developed an XPAK form factor solution for 10 Gigabit I/O applications. The XPAK system consists of a XLink(TM) 10 Gigabit optical transponder, guide system, and 70-pin XAUI host connector.
These Molex products are designed to the XPAK multisource agreement (MSA). The first products from Molex are designed for low profile applications. These modules have a maximum profile of 9.8 mm and are PCI compliant. Typical applications include network interface cards (NICs), host bus adapters (HBAs), target channel adapters (TCAs) and dense packed storage area network and enterprise switches. This next generation form factor is approximately one half the size of the current generation XENPAK 10 Gigabit MSA form factor.
XLink(TM) 10GBASE-LR Optical Module
The XLink optical transponder is designed to the IEEE 802.3ae 10GBASE-LR PMD standard. There are four lanes of XAUI data input at 3.125Gbps (for Ethernet) or 3.1875Gbps (for Fibre Channel) per lane. These lanes are electrically multiplexed to a
single channel that modulates an uncooled DFB laser at 10.3 or 10.5 Gbps. The 8B/10B data stream is re-encoded to 64B/66B and can be transmitted up to 10 km over standard singlemode fiber. Molex's proprietary optical packaging design ensures efficient optical coupling, high reliability, and low cost.
Molex's 10-GBASE-LR modules are available in two versions for use in either 10 Gigabit Ethernet or 10 Gigabit Fibre Channel protocol applications. The modules are hot pluggable, operate off a 3.3V and 1.8V power supply and utilize a SC duplex optical
interface. They cover approximately 36 x 69mm of board space. Samples of the XPAK XLink modules will be available in Q4 2002.
Guide System
Molex's guide system allows for above board Z-axis pluggability. The low profile guide system is PCI compliant. To ensure low electrical magnetic interference (EMI), the guide system shields the host connector that includes a ground tab across the front of the connector. An optional EMI gasket can be used to ground the guide system to the faceplate. Two additional mounting placements are available to seal either the front or back of the bezel. For applications where the faceplate is painted the back sealing can be used. For plated faceplates the front sealing is optimal. Both solder mount and press fit guide system prototypes are available. The mounting pins have been arranged to allow
for "belly-to-belly" mounting requirements. Prototypes will be available in Q4 2002.
SMD Host Connector
The 70-position host connector features SMT leads in an edge-card configuration and is part of the Z-axis pluggable family of Molex products. The connector provides a compact, high bandwidth connection to support the XAUI (10-Gigabit Attachment Unit
Interface) electrical interface. The XAUI interface defines four parallel lanes of differential data, each operating at 3.125 Gbps for 10 Gigabit Ethernet protocol or at 3.1875 Gbps for 10 Gigabit Fibre Channel protocol. The connector also supports the
emerging SF14 phase 2 interface for SONET OC-192 applications. SFI4 phase 2 defines four parallel lanes of differential data at 2.488 Gbps per channel.
The standard connectors are available with either 0.15 micro inch or 0.30 micro inch of gold plating. These are now in production and are available in 480-piece tape and reel.
