Microsemi’s multichannel universal 10G PHY with OTN/FEC device
provides highly fl exible XAUI/SFI-4.2/TFI-5 to XFI transceiver capability
with optional OTN wrapper for 10 GbE, 8G/10G Fibre Channel,
OC-192/STM-64, and OTU2 applications.
The Microsemi VSC8494 quad Universal 10G PHYs with OTN-FEC
are ideal for Carrier Ethernet switch/router and DWDM systems.
Cost-effi cient transponders based on the VSC8494 device cater to
high volume 10 GbE/10G SONET/SDH and 8G/10G Fibre Channel.
The VSC8494 device offers the ideal solution for multiport client and
network interfaces on telecom transport linecards, transponders, and
muxponders.
This highly integrated device supports 10 GbE LAN Carrier Ethernet
networks, as well as WAN and OTN networks, with an extensive suite
of 10 GbE mapping modes. With its 10G PHY XFI/SFI interfaces and
G.709 FEC features, the VSC8494 quad device provides a seamless
and direct interface to XFP and SFP+ optical modules.
The Microsemi VSC8494 quad device employs a bidirectional,
independent channel architecture that can be used in both transponder
(adaptation) and regenerator modes. Bidirectional performance
monitoring is supported in both cases. The OTN mapper with FEC
supports performance monitoring and maintenance features defi ned
by the ITU-T G.709 standard, independent of the client signal carried,
to simplify the operation of optical networks supporting various client
signals.
The VSC8494 quad device includes four 10 Gbps dual-mode
bidirectional UPI client interfaces and four 10 Gbps bidirectional serial
interfaces for direct connection to XFP or SFP+ optics modules or 10G
serial backplanes.
The Microsemi-defi ned Universal PHY Interface (UPI) delivers 10 GbE
and 10 GFC as four-lane XAUI, 10G SONET/SDH as four TFI-5-like
serial lanes, and OTU2/ODU2 as four-lane SFI4.2-like interface. UPI also
supports twice-rate XAUI (DDR XAUI or RXAUI) as two lanes operating
at 6.25 Gbps, and twice-rate SFI-4.2 for OTU2/ODU2.
