400G CDFP Vs. CFP8 Module

400 Gigabit Ethernet was planned to be released in December this year. It is designed to meet IEEE P802.3bs Task Force standard and to apply to both metro and long-haul networks. The 400GbE operates over 100 m of multimode fiber, 500 m of singlemode fiber, 2 km of SMF, and 10 km of SMF. 400G CDFP and CFP8 are two form factors of 400G Ethernet technology. This article would give a introduction to 400G CDFP and CFP8 modules and make a comparison between them.

400G Ethernet

Introduction to 400G CDFP Module

The CDFP is short for 400 (CD in Roman numerals) Form factor Pluggable, which is designed to provide a low cost, high density 400 Gigabit Ethernet solution. It features as front panel, hot-pluggable, 16 channel and 400 Gbps module. CDFP will be a short reach module, which enables 4 Terabit line cards. From the perspective of interface, it is very similar to the QSFP and CXP module. CDFP developers have targeted using the developing IEEE802.3bs specification for Ethernet 400GBaseSR, 400GBaseLR.

Information About 400G CFP8 Module

Following CFP2 and CFP4 naming, CFP8 module was proposed in the year 2015. CFP8 is a new form factor which is still under development by members of CFP8 MSA. The form factor of CFP8 is amounting to CFP2, but it supports 4 × 100G and 400G, for example, 4×CFP2’s 1×100G. The CFP8 uses a new 16 × 25G electrical I/O connector. The CFP8’s interface has been generally specified to allow for 16 × 25 Gb/s and 8 × 50 Gb/s mode. From the point of bandwidth density, the CFP8 module is eight times larger than the CFP module and four times larger than the CFP2 module.

400G CFP8 module operation

Figure3: 400G CFP8 module operation

Example IEEE specifications supported by CFP8:

400GBASE-SR16 parallel MMF (16x25G NRZ)
400GBASE-FR8/LR8 duplex SMF (8x50G PAM4 WDM)
400GBASE-DR4 parallel SMF (4x100G PAM4)
CDAUI-16, CDAUI-8

Figure4: Form factors of CFP modules

Among all the specifications on the above, 400GBaseDR4 is the most revolutionary one. 400GBaseDR4 uses 4x100G parallel SMF PAM4 signaling technology. This technology is also aimed at fitting in the CFP4 21.5-mm width module size, while using 12 (SMF) fibers within a 1×12 MPO optical connector and the host board electrical 56-pin edge connector.

Low power consumption is also a distinctive feature of CFP8. Active optical modules have been widely deployed in the process of data transmission, but some of them or some copper applications really cost a lot and consumes much power. CFP8 module uses internal mid-board optical or electrical interconnect flyovers and bulkhead MPO or MXC connectors to connect the switch. This reduces power consumption to a great extent.

400G CFDP Vs. CFP8

—Form factor

CDFP was proposed earlier than CFP8, it has larger form factor than CFP8.

—Supported fiber type

CDFP supports passive and active copper cable, active optical cable and multimode fiber while CFP8 supports singlemode and multimode fiber.

—Transmission distance

CFP8 modules support longer data link distance compared with CDFP modules.

—Applications

The CDFP modules provide a very versatile solution for data center interconnects. CFP8 would be used in high-density 4x100GbE fan-out applications, such as datacom applications or in ITU-T for telecom applications.

Conclusion

This article mainly discussed about CDFP, CFP8 and their differences in form factor, supported fiber type, transmission distance and applications. There is no doubt that 400G Gigabit Ethernet is an irresistible trend for future Ethernet development.

Broadcom or Intel Network Adapter for Dell PowerEdge Server?

The NDC, Network Daughter Card (also known as Select Network Adapters), is an innovation technology developed by Dell. As an advanced technology on server, the NDC provides the customers with a flexibility of choosing what they want ( 4 x 1GbE, 2 x 10GbE or 2 x Converged Network Adapter.) With this small, removable mezzanine card, we are no longer limited to use network interface cards (NICs) on the motherboard. And it has been used in the twelfth-generation Dell PowerEdge server. This article will focus on Broadcom or Intel network adapter for Dell PowerEdge Server.

About Select Network Adapter

Network adapter plays an irreplaceable role in a server system, as it can reduce CPU usage on the server, which improves the overall system performance. NDC is a paramount member of Dell PowerEdge Select Network Adapters family. There are two form factors of Select Network Adapters—blade servers and rack servers. (You can see the two servers clearly in the following figure.) The Blade Select Network Adapter provides dual port 10GbE from various suppliers. The Rack Select Network Adapter provides a selection of 1GbE and 10GbE port options, such as 1000Base-T, 10GBASET and 10Gb SFP+.

How to Choose the Optical Cables and Modules for Broadcom or Intel Network Adapter?

Just take Broadcom 57800S 2x1Gb+2x10Gb SFP+ NDC for example. A Broadcom 2 x 1G + 2 x 10G SFP+ NDC provides two 1000BASE-T ports and two 10G SFP+ ports as shown in Figure 6. We can plug two Dell compatible SFP transceivers into the two 1G ports on the Broadcom NDC respectively to achieve 1G network connection. Likewise, we can also connect Dell compatible SFP+ transceiver such as 10Gb Base SR connector to the 10G port on the Broadcom card for making 10G data transferring. Besides, we can also use Direct Attach Cable (DAC) to achieve 10G network connectivity, such as multimode 10Gb fiber optic cable, Dell 10G SFP+ DAC cable. DAC cables provide a cost-effective solution for very short transmission while 10G optical modules are more suitable for data transferring over long distance.
