2G5 GFP-T (CODEC)

Overview

Aliathon’s 2.5Gbps GFP-T Encoder Core provides a flexible, resource-efficient, high-density programmable logic based solution for GFP interfacing.

The core encodes 8B/10B signals and maps them into fixed length transparent GFP blocks. The Core also simultaneously extracts the 8B/10B signals from received GFP-T blocks.

Key Features

  • Compliant with ITU-T G.7041 specification.
  • Best-in-Class size and performance. Multiple FPGA vendor support.
  • Accepts 64 byte blocks of data from an 8B/10B data source.
  • Encodes input blocks into 67 byte GFP-T blocks as per G.7041.
  • Calculates block CRC-16 and verifies block CRC-16.
  • Extracts 64 byte 8B/10B blocks of data from GFP-T frames.
  • Supports multiple blocks per GFP frame.
  • Supports multiple channels using GFP Extension Header channel ID.
  • Inserts/detects 10B_ERR code for unrecognised K characters. Inserts/detects 65B_PAD code for rate adaptation.
  • Interfaces to Aliathon’s GFP Framer core for GFP transmission.
  • Overhead and Defect processing including:
    • CRC error.
    • Performance Monitoring Counter (CRC).
