High-density SONET/SDH framers
11 November 2009, Telecoms, Datacoms, Wireless, IoT

Exar has expanded its Tethys product with the introduction of Tethys II devices, high-density SONET/SDH framers comprised of the PEB2756 and PEB2757 which deliver 40G of bandwidth in a single device. The new parts provide a flexible feature set that can be coupled with optical transport network (OTN) devices to enable next-generation line cards for optical networking.

The Tethys II devices are single-chip solutions that integrate functions including aggregation of up to 16 channels of traffic, serialising/deserialising, pointer processing, clock and data recovery, as well as transport overhead (TOH) and path overhead (POH) processing. The PEB2756 supports four OC-192/STM-64 channels. The PEB2757 supports four OC-192/STM-64, 16 OC-48/STM-1, 16 OC-12/STM-4 or 16 OC-3/STM-1 channels, which can be mixed in any combination. Both devices support aggregate throughput up to 40 Gbps while meeting stringent SONET/SDH jitter requirements.

The Tethys II family allows ports to be independently configured for different data rates, permitting ‘any port, any rate’ implementations and by providing a direct interface to optical modules. This allows equipment to be programmed in the field by simply changing the optical modules, enabling service providers to purchase one card for use in multiple applications.

The on-chip SERDES, clock and data recovery (CDR) and clock multiplier unit support 2,5 Gbps, 622 Mbps and 155 Mbps multirate I/O which connect directly to

multirate SFP optics. The line-side interfaces for the Tethys II devices include programmable serial SERDES ports as well as the SFI-4.1 and SFI-4.2 interfaces required for the OC-192/STM-64 mode and connection to 10 Gbps OTN / FEC devices. The system-side interface for both devices supports TFI-5.
