Huawei CR5D0EFGFE70

The Huawei CR5D0EFGFE70 is a high-density 48-port 40 Gigabit Ethernet (40GE) interface card designed for the Huawei NetEngine 5000 and 8000 series core routers. This card is used in scenarios where massive bandwidth aggregation is required, typically in the core of data centers or service provider networks.

Decoding the Model Number: CR5D0EFGFE70

• CR: Core Router

• 5: Series generation (NetEngine 5000/8000 family)

• D0EFGF: This is the functional code for the card:

  • The "EFGF" strongly indicates a 40GE interface card.

  • The "D0" likely refers to the port density and hardware version.

• E70: A specific version or revision code for this card model.

In simple terms, this is a 48-port 40GE QSFP+ line card.

Key Features and Capabilities

This card is designed for the highest levels of bandwidth aggregation in a core routing environment.

1. Extreme Port Density and Speed:

   • Provides 48 ports of 40 Gigabit Ethernet in a single slot.

   • This represents a massive 1.92 Tbps of full-duplex bandwidth in a single line card.

   • It allows a core router to aggregate traffic from multiple 10G/40G/100G links.

2. QSFP+ Form Factor:

   • Uses QSFP+ transceivers, which provide significant flexibility:

     • QSFP+ 40G-SR4/LR4 for native 40G connections

     • QSFP+ to 4x SFP+ Breakout Cables to split one 40G port into four independent 10G ports

     • QSFP+ DAC (Direct Attach Copper) for short in-rack connections

3. Breakout Capability:

   • A key feature is the ability to use breakout cables to turn each 40G port into four 10G ports.

   • This means the card can be configured as:

     • 48 ports of 40GE, OR

     • 192 ports of 10GE (using breakout cables)

   • This provides tremendous deployment flexibility.

4. High-Performance Design:

   • Built with Huawei's custom Solar series chipsets to handle line-rate forwarding on all ports.

   • Integrates with the router's central switching fabric without bottlenecks.

5. Carrier-Grade Reliability:

   • Hot-swappable design

   • Supports all advanced routing features (MPLS, Segment Routing, EVPN)

Key Specifications

How It Fits into the Network

This card would be installed in chassis like the CR5P08BASA7D (8-slot) or CR5P03BASA75 (3-slot):

• Data Center Core: Aggregating traffic from top-of-rack switches that have 40G uplinks.

• Service Provider Aggregation: Concentrating traffic from multiple 10G/40G links from aggregation routers.

• Network Modernization: Upgrading network capacity from 10G to 40G in the core.
