Do You Know About SFP-H10GB?

The SFP-H10GB is high performance, cost effective solution for 10G Ethernet and 10G Fibre Channel applications. It is commonly covered in direct attach copper cable. The main components are one string of copper cable and two connectors at each end. The transceiver modules achieve high port density, configurability and utilization at a very low cost and reduce power budget. The high speed assemblies meet and exceed Gigabit Ethernet and Fibre Channel industry standard requirement of performance and reliability. The main applications of it are Storage Area Networks, Network Attached Storage, Storage Servers, data center cabling infrastructure, high density connections between networking equipment.


Twinax Cable
All the cable types of SFP-H10G belong to twinax copper cable. Twinax cable is a kind of cable which is very similar with coaxial cable. We can say that twinax cable is the doubled coaxial cable. The word “coaxial” comes from the inner conductor and the outer shield sharing a geometric axis. Coaxial cable used for carrying low-frequency signals, in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a transmission line. As an advanced coaxial cable, twinax cable has two inner conductors instead of one. Due to cost efficiency, it is becoming common in modern very-short-range high-speed differential signalling applications.
Types of SFP-H10G
There are two common types of SFP-H10G twinax cable, active twinax cable and passive twinax cable. Active twinax cable is mainly for long length transmission while passive twinax is for short length. (The long or short length here is compared in a relatively range.) We will provide detail information about SFP-H10G based on the classification of active twinax cable and passive twinax cable.
SFP-H10G Active Twinax Cable
An active copper cable carries a 10 Gig Ethernet signal with the use of signal boosting technology. Active copper cables contain electrical component that is a silicon chip (semiconductor) that boost signal levels. This makes active copper cables slightly more expensive than passive copper cables; however, they can connect the Converged Network Adapter (CNA) to a top-of-the rack switch over long distances than passive copper cables. In terms of its long transmission lengths, an active SFP-H10G twinax cable has some common types, such as SFP-H10GB-ACU3M, SFP-H10GB-ACU7M, SFP-10GACU10M... They are highly compatible with equipment and guaranteed to meet or exceed specifications for quality, performance and functionality.
SFP-H10G Passive Twinax Cable
A passive twinax cable carries a 10 Gig Ethernet signal over short lengths (5m or under) of copper with no additional component to boost signal. On the basis of different transmission lengths, it also can be divided into several types, such as , SFP-H10GB-CU1M, SFP-H10GB-CU2M, SFP-H10GB-CU5M... Just taking the SFP-H10GB-CU5M for an example to give further explanation. The SFP-H10GB-CU5M features a 30 gauge (30AWG) copper cable with a 10GBase SFP+ fiber optic connector on each end, allowing for excellent EMI protection and dependable performance. It offers an affordable solutions for data transmission over short distances up to 5 meters high. It is typically employed for connections within a network rack and/or across an adjacent network rack.
Summary
With all cables, length and signal strength are always something to look into. For shorter distances, it is common practice to use passive cables as they are rated for ranges up to 5m and provide a good working solutions at a great cost. You can choose an appropriate one based on your need, such as SFP-H10GB-CU1M, SFP-H10GB-CU3M, SFP-H10GB-CU5M... When the distance between connection points that exceed 5m, it is highly recommended to use active cables to ensure signals are transferred all the way through, such as SFP-H10GB-ACU7M and SFP-10GACU10M. The cost may be a bit higher, but the signal is improved and gives peace of mind by creating a trustworthy connection.

In contemporary world, the Internet users have experienced the great changes brought by 10 Gigabit Ethernet and 40 Gigabit Ethernet. For most Ethernet users, 10/40GbE is more than sufficient, however, not enough for the increasingly growing enterprise networks. In order to enhance the efficiency of Gigabit Ethernet network, developers in data center researched and found out a solution—100 Gigabit Ethernet. 100 Gigabit Ethernet (100GbE) is groups of computer networking technologies for transmitting Ethernet frames at rates of 100 gigabits per second (100 Gbit/s), which conforms with 802.3bm-2015 standards. 100G Ethernet significantly improved efficiency on all aspects, such as bandwidth, space, power...There are many form factors of 100G transceivers including CXP, CFP, CFP2, CPAK, CFP4 and QSFP28.
