What is SFP+ Direct Attach Copper Cable?

 Direct Attach Copper, referred to as DAC.It is including two kinds:

1.SFP+ DAC 10G;

2.QSFP+ 40G turns 4 SFP+.

This cable can not replace the port, can only be replaced together with the product line, the module

head and the copper can not be separated.Today we will introduce the SFP+ DAC cable,mainly to talk about what is SFP+ DAC Cable? We will also talk about its features and advantages.


What is SFP+ Direct Attach Copper Cable?

SFP+ DAC Cable is a copper interconnect using a passive twin-ax cable assembly that connects directly into an

SFP+ housing. It is low power, low cost and low latency with the added advantage of having the small form factor of SFP+, and smaller, more flexible cabling.


SFP+ DAC Cable is a low cost technical solutions to alternative 10G optical module. Widely used for the short-distance high speed Internet, such as gigabit network card,

Gigabit switch, million server, super computer, cloud computing, cloud storage network, etc.fiber-mart.com can provide you with 1 meter to 15 meters 10G SFP+ high-speed cable.

1pc of SFP+ high speed cable =（2pcs of SFP+ 10G modules+one pair of OM3 10G fiber pigtail）

1. Working temperature: 0 ~ 70°C, 3.3V power supply, low power consumption: <2.0W

2. Support hot pluggable, meet the standard of SFP MSA products

3. Meet the SFF-8431 standard and used for the electrical interface of 10GB Ethernet and 10G fiber channel

4. Two line interface to meet the management standards of SFF-8472 digital diagnostic monitoring

5. Main application range:

※ Large capacity I/O storage area network, network attached storage and storage server

※ Exchange type I/0, such as ultra-high bandwidth switches and routers

※ Data center cabling infrastructure

※ Connection between high-density network devices

※ 1-8G fibre channel and 1-10G Ethernet



Product features:

Common Armored Fiber Optic Cables

  Armored fiber optic cables are often installed in a network for added mechanical protection, as they have extra reinforcing in the cable housing to prevent damage. Two types of armored fiber optic cables exist: interlocking and corrugated. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. It offers ruggedness and superior crush resistance. Corrugated armor is a coated steel tape folded around the cable longitudinally. It is found in outdoor cables and offers extra mechanical and rodent protection.   The Structure of an Armored Fiber Optic Cable In basic armored fiber cable designs, the outer sleeve provides protection against wind, solvents, and abrasion. This outer sleeve is usually made of plastic such as polyethylene. The next layer between the sleeve and the inner jacket is an armoring layer of materials that are difficult to cut, chew, or bu

what the Differences Between FBT Splitter and PLC Splitter

  In FTTx and PON architectures, optical splitter plays an increasingly significant role to create a variety of point-to-multipoint fiber optic networks. But do you know what is a fiber optic splitter? In fact, a fiber optic splitter is a passive optical device that can split or separate an incident light beam into two or more light beams. Basically, there are two types of fiber splitter classified by their working principle: fused biconical taper splitter (FBT splitter) and planar lightwave circuit splitter (PLC splitter). You may have one question: what’s the difference between them and shall we use FBT or PLC splitter?   What Is FBT Splitter? FBT splitter is based on a traditional technology to weld several fiber together from side of the fiber. Fibers are aligned by heating for a specific location and length. Because the fused fibers are very fragile, they are protected by a glass tube made of epoxy and silica powder. And then a stainless steel tube covers the inner glass tu

Introduction of Optical Fiber Couplers and How Do They Work?

 What are optical fiber couplers? A fiber optic coupler can be defined as an optical component used with one or more input fibers and several output fibers in fiber optic systems. A coupler essentially puts two or more cores of fibers together to connect. The simple coupler is the fused fiber 2x2 coupler. Couplers are used as multiplexers that are resistant to certain wavelengths. A fiber output depends on the wavelength of light and the frequency of polarization. The fiber refractive index also plays a significant role in the performance. Let’s checkout how do optic couplers work to understand this better. How do fiber optic couplers work? Either fiber optic couplers separate optical signals into multiple paths or combine multiple signals in one direction. Optical signals are more complicated than electrical signals, making it more difficult to design optical couplers than their electrical copy. Unlike electrical currents, the optical signal consists of a stream of signal carriers, in
