Introduction
In today’s fast-paced world, high-speed internet connectivity is crucial. Without it, we can’t stream videos, download files, or work on important projects. That’s where the QSFP28 comes in – a new and powerful type of connector that guarantees lightning-fast speeds. However, when looking to purchase this tech, the prices can seem daunting, and customers may feel overwhelmed. With this post, we investigate the top 4 types of QSFP28 connectors, their prices, and what makes them unique.
Types of QSFP28 Connectors
- AOC: Active Optical Cables, best suited for high-density data center applications.
- DAC: Direct Attached Cables, best suited for short distance connections.
- SFP: Small Form-Factor Pluggable, a compact, highly flexible interface.
- SFP-DD: Small Form-Factor Pluggable Double Density, optimized for even higher data rates.
Each of these connectors has its own set of benefits and select use cases. Prices typically range from under $100 to over $1,000, depending on the type, brand, and length of the cable.
AOC Connectors for High-Density Data Center Applications
Active Optical Cables are ideal for high-density data center applications that require longer distances ranging from 1 to 100 meters. They function by utilizing fiber optic cables to transmit data between switches, servers, or other network devices. AOC QSFP28 is built to handle various high-data rate applications such as 100 Gigabit Ethernet, Infiniband EDR/FDR, and Fibre Channel. Top brands include Amphenol, Finisar, and Sumitomo Electric.
DAC Connectors for Short Distance Connections
Direct Attached Cables, or DAC cables, are a cost-effective solution for high-speed connectivity with a range of 1 to 7 meters. They offer a flexible connection option to servers, switches, routers, and adapters, providing reliable power at a lower cost than the AOC. Additionally, it is lower power consumption and more compact. Top brands include Mellanox, Cisco, and FS.
SFP Connectors – Compact and Flexible
SFP is a small form factor pluggable transceiver designed for high-speed communication applications that require a small space. These optical modules use LC fiber optic and are hot-swappable, allowing the user to replace modules on-the-go. SFP QSFP28 modules are ideal for enterprise applications with small connectors and custom configuration options. Top brands include Juniper, Arista, and Dell.
SFP-DD Connectors for Extra Speed
SFP-DD Double Density is the ultimate option when it comes to high-speed communication requirements, providing even faster speeds than SFP modules. These QSFP28 SFP-DD modules are optimized for next-gen Ethernet and InfiniBand architectures, reaching speeds up to 400G. These connectors are becoming increasingly popular in data centers as they deliver high bandwidth, long-range signal transmission, and perfect heat dissipation parameters. Top brands include Broadcom, Intel, and Mellanox.
The Price of QSFP28 Connectors
The price of QSFP28 connectors ranges from $70 to $1,000, depending on their length, type, and brand. Generally, DACs are the most affordable of all the QSFP28 connectors, with prices ranging from $50 to $100. In contrast, Active Optical Cables are more expensive, starting from $200 and sometimes exceeding $1,000. SFP and SFP-DD connectors are also moderately priced, ranging from $150 and $600. It is always wise to compare prices from different vendors and research the specifications before making a purchase.
FAQs
Q: What is a QSFP28 connector?
A: A QSFP28 connector, or Quad Small Form-Factor Pluggable 28, is a high-speed transceiver designed to offer maximum data speeds with low power consumption.
Q: How does an AOC connector differ from a DAC?
A: AOC relies on fiber optic cables to transmit data across longer distances, while DACs use copper cables and are better suited for short distances.
Q: Can QSFP28 connectors be hot-swappable?
A: Yes. QSFP28 connectors are generally hot-swappable, letting you replace modules as you go without shutting the whole network down.
Q: Are QSFP28 connectors backward-compatible with QSFP+ transceivers?
A: Yes. They are backward-compatible with QSFP+ transceivers, so they can be easily replaced or upgraded while maintaining existing hardware.
Q: Can I plug four QSFP28 connectors simultaneously into a QSFP28 port?
A: Yes. QSFP28 ports can accommodate up to four QSFP28 connectors in a plug-and-play setup, providing full high-speed connectivity.
Q: Which QSFP28 connector should I choose for high-data rate applications?
A: Active Optical Cables and SFP-DD modules are best suited for data rates above 100Gbps, while DACs and SFPs are ideal for lower data rates.
Q: How can I ensure that I get the best price on QSFP28 connectors?
A: To get the best deal on QSFP28 connectors, research different brands and vendors, compare prices and specifications before deciding, and purchase in bulk to receive volume discounts.
