Vitesse debuts first OTN mappers with support for IEEE 1588v2, ITU Y.1731

Vitesse Semiconductor Corp., a provider of IC solutions for carrier and enterprise networks, introduced a multi-port 10 Gigabit Ethernet (GE) optical transport network (OTN) mapper family, including the VSC8492 and VSC8494.

This mapper family, with a smaller footprint than competitive devices, is the first to support both IEEE 1588v2 and Y.1731 time stamping, making them well suited to timing, synchronization, and real-time performance monitoring over a packet transport network.

The Vitesse 10GE OTN mappers enable service providers to accelerate the convergence of packet and TDM services by supporting 10GE Universal PHY Interfaces (UPI), including 10GE LAN/WAN, SAN, SONET/SDH, and OTN. When used in conjunction with Vitesse’s pin-compatible 10G Ethernet and OTN PHY devices, the VSC8492 and VSC8494 enable carrier ethernet switch router (CESR) and packet optical transport platform (POTP) vendors to add OTN interfaces to their equipment in the most cost-effective manner.

The VSC8492 and VSC8494 mappers were designed with flexible network use in mind. Embedded forward error correction (eFEC) support enables use with legacy FEC-based OTN solutions. XFI/SFI ports on line and client side allow the mappers to be used with XFP and SFP+ optical components; with the redundancy of the XFI/SFI ports, the mappers support both 1+1 and 1:1 protection switching. Use of XFI/SFI provides a range of options for 10G backplane support, including 10GBASE-KR. The mapper family also supports several timing options for Synchronous Ethernet implementations.

“In past generations of transport mappers, SONET/SDH/OTN and Ethernet have followed two independent evolutionary paths,” says Andy Ebert, product marketing manager at Vitesse. “We have designed this OTN mapper family to be as flexible as possible, in part by giving it the ability to support protection-switching, time stamping, and performance monitoring services of modern carrier Ethernet networks.”
