The Apodis IPL4402A OTN processors ASICs are a Transponder member of Tera-Pass’ product family for access applications. Apodis IPL4402A processors support the functionality required by Premium Services networks. Apodis IPL4402A’s client-side supports up to 2 multi-service ports and multiplexes them to 2 OTU2 (10.7/11.1 G) bearers.
20G OTN Processor, Transponder
Overview
Key Features
- 2 Client Ports support up to 2 10GE signals presented through 2 multi-rate interfaces. The 10GE signals can be accepted through serial or parallel XAUI interfaces.
- 2 Client Signal Processors, each capable of supporting 10G of Client Traffic, implement the Ethernet functionality.
- A Transparent Agnostic Fabric (TAF) provides non-blocking, unidirectional, bi-directional and unrestricted multicast connectivity.
- 2 Line Signal Processors, each capable of supporting up to 10G of Line Traffic, implement the functionality of OTU2 bearers.The 2 OTU2 signals can be presented over serial or parallel SFI4.2 interfaces.
- A 32-bits parallel control bus supports Intel and Freescale operational modes.
- An External Overhead Interface (EOI) provides round-robin access to all the GCC channels of OTN signals, to all the DCC channels of SDH/SONET signals and Read/Write (R/W) to the entire overheads of OTN signals. Special built-in logical operators allow to implement additional functions on OTN overhead fields.
- Apodis OTN processors operate off a single 155.52MHz reference clock. No additional external circuitry is needed to support the wide variety of protocols and bitrates of its Client and Line interfaces. Integrated jitter attenuators with variable filter poles meet the most stringent requirements for Jitter Generation, Accepted Jitter and Transfer Jitter.
