Diplomat™-ONT-G MDU

GPON ONT MDU/MTU System-on-Chip (SoC) (TXC-07034)

Summary

The Diplomat^TM-ONT-G MDU/MTU is a highly integrated, programmable single-chip SoC designed to address the needs for high performance Optical Network Termination equipment. Supporting the performances required for Multi-Dwelling Units (MDU) and Multi-Tenant Units (MTU) GPON-based units, this cost-effective solution offers flexible Ethernet connectivity to the Customer Premises Equipment. The Diplomat^TM-ONT-G has embedded CPU interface to support the OMCI protocol stack and integrated SerDes and CDR for GPON connectivity.

Diplomat^TM-ONT-G MDU/MTU is a member of the TranSwitch GPON portfolio. Its compati-ble with the solutions offered for Single Family Units (SFU) and Single Business Units (SBU) applications using the Diplomat^TM-ONT-G SFU/SBU.

The Diplomat^TM-ONT-G device is the latest addition to TranSwitchÆs robust Diplomat^TM family of FTTx last mile customer premises access solution. TranSwitch's Gigabit Passive Optical Network (GPON) solution is Full Service Access Network (FSAN) compliant, to meet triple play service demands for MDU/MTU applications. TranSwitch provides a complete solution including, embedded firmware load, device driver, APIs evaluation and evaluation kit with the device for supporting last mile PON access link. Data rates of up to 2.488 Gbps downstream and up to 1.244 Gbps upstream PON enables service providers to provision native TDM, Ethernet, and packet service qualities manifested in high bandwidth. TranSwitchÆs family of high bandwidth devices supports 1:128 split ratio, enabling 128 ONTs on a single GPON link. In addition to packet services, the TranSwitch family of devices enables native TDM and ATM services to be delivered over GPON.
