FS.COM SFP+ Direct Attach Cable Solution

Meeting the ever growing need to cost-effectively deliver more bandwidth, FS.COM SFP+ Direct Attach Cable delivers lower power, lower latency and higher density for today’s Data Centres and Storage Area Networks.

SFP+ DAC Cables are a low cost alterna-tive to traditional fibre and twisted-pair copper cabling in top-of-rack and middle-of-row Data Center deployments.

In today’s Data Center, more bandwidth is needed to support the use of server virtualization where multiple virtual machines are combined on a single physical host server. To accommodate the ever-growing number of operating systems and applications residing on individual servers, virtualization requires significantly increased data transmission between the servers and switches.

At the same time, the amount and type of devices residing on the network have dramatically increased the amount of data that needs to be transmitted to and from storage area networks (SANs) and Network Attached Storage (NAS). Depending on recent industry forecasts, the amount of enterprise data being transmitted will grow at more than 20% between 2011 and 2016. Consequently, Data Centre managers are looking for cost-effective methods to provide more bandwidth, while optimising power consumption and supporting modularity and scalability.

To meet these requirements, FS.COM has expanded its line of Data CentreSolutions to include SFP+ Direct Attached Cables. A low cost, low power consumption and low latency solution that is ideal for high-density, in-rack 10 gigabit per second (Gb/s) connections between servers and switches, SFP+ Direct Attached Cables feature rugged twinaxial cables that connect directly into a low-profile small form-factor pluggable plus (SFP+) diecast connector housing.

FS.COM SFP+ Direct Attached Cables offer the smallest 10 gigabit form factor and a small overall cable diametre for higher density and optimised rack space in 10 gigabit Ethernet (GbE) uplinks and 10 gigabit Fibre Channel SAN and NAS input/output connections. The use of SFP+ Direct Attached Cables can cost up to three times less than fibre optic solutions, while offering lower latency and consuming up to 50% less power per port than current copper twisted-pair cabling systems.

Becoming increasingly popular for short distance top-of-rack (ToR) and middle-of-row (MoR) Data Centre deployments, and expected to account for over 40% of 10 gigabit equipment ports, SFP+ Direct Attached Cables also provide enhanced scalability and flexibility. By connecting several servers or storage devices together in a single rack, the use of intermediate patch panels is eliminated and cabling outside of the rack is limited to the main switch connection, making it easy to move racks, deploy one rack at a time and isolate cabling changes to a single rack.

SFP+ Direct Attached Cables provide better cable management for high-density deployments and enhanced electrical characteristics for the most reliable signal transmission.

FS.COM SFP+ Cables

SFP+ fibre cable solution is suitable for longer distance communication, while 10G SFP+ cables solution is best when utilized in short lengths, typically 15m or less, which is sufficient to link server cards and switches. But at present, the fibre and copper cable transmission standard of 10G Ethernet have been launched. However, there is only the fibre standard without copper standard for the 40G Ethernet transmission now.

QSFP+ cables and SFP+ cables

From the perspective of the development of wiring, generally, the standard of copper cable is always behind the fibre standard and the application standard. Currently, the TIA and ISO have already established a working group to carry out the research work of the copper standard.

Actually, the QSFP+ cable is a choice for short transmission distance. Generally, QSFP+ cables are used to connect the ToR switches.

SFP Transceiver for Cisco 3560 Series Switches

Optical Transceiver Module

The optical transceiver Module used for optical-to electrical conversion is a key component in optical communication systems. Fibre Optic Transceiver Module is a self-contained component that can both transmit and receive. Usually, it is inserted in devices such as routers or network interface cards which provide one or more transceiver module slot (e.g GBIC, SFP, SFP+, XFP). SFP module is a compact optical module used in optical communications. The SFP is short for small form-factor pluggable and also called Mini-GBIC (the upgrade version of GBIC). The SFP module has many applications in both telecommunication and data communications. This article focus on picking SFP transceivers for Cisco 3560 switches.

About Fiber Optic Transceiver Types

Fibre optic transceiver types are various and support many different cabling media and application speeds. You may hear words like, GBIC, mini-GBIC, SFP, SFP+, XFP and others. These support different rates and have different form factors.

A Gigabit Ethernet interface converter (GBIC) is a standard used for the kind of fibre optic transceivers that can be plugged into switches and media converters. This method of plugging a fibre optic transceiver into a GBIC module slot of a switch, as opposed to having a fixed interface, is also called hot-swappable since the transceiver is loaded into the switch while the switch is powered on. The GBIC standard is determined in the SFF Committee in document number SFF-8053. GBIC transceivers are offered in the -SX, -LX, and -ZX wavelengths and media ranges.

GBICs were created to provide both a small form factor and the flexibility to plug a number of transceiver types into a common electrical interface for Gigabit Ethernet speeds. When a variety of optical port types are needed, an IT administrator can buy GBICs as needed. This lowers the expense of the overall switch system and gives the IT administrator much more flexibility, since they have the choice of different fibre optic transceiver types. However, if the switch is intended to mostly have one port type, then it will probably be cheaper and take up less space per port to use a switch with that port type built into it. The back of the device has an electrical adapter that plugs into a switch. The front of the transceiver has a SC connector interface for the two 850nm optical ports suitable for use over multimode fibre. One is used for transmitting and the other for receiving signals.

A smaller kind of the GBIC is called a mini-GBIC or SFP (small form factor pluggable) module. It serves the same purpose as the GBIC but has a smaller footprint. To allow for the smaller footprint, SFPs use LC connector interfaces. SFPs are also offered a 1000-Base-T reference to an RJ-45 interface.

The XENPAK transceiver was standardised in 2001 to support 10 Gigabit Ethernet over fibre optic media and copper media. These come in a number of optical media types and wavelength ranges and also support copper media using a -CX4 interface. They’re much bigger in dimension than GBICs and SFPs. After XENPAK was standardised, XPAK and X2 are created to supply a smaller footprint for 10 Gigabit Ethernet. These products share exactly the same electrical interface as XENPAK but are lighter. The XFP small form factor pluggable transceiver was initially developed in 2003 to supply a smaller form factor transceiver for 10Gbps applications than XENPAX, XPAK, and X2 transceivers.

XFP was created by the XFP Multi-Source Agreement Group prior to the development of the SFP+. XFPs supports 10 Gigabit Ethernet, SONET/SDH, and Fibre Channel applications. In keeping with their small form factor, much like SFPs, XFPs use an LC connector interface. XFPs are set up in a similar fashion to GBICs and SFPs, are available in many media type and wavelengths.

The SFP+ transceiver module was created later to assistance 10 Gigabit Ethernet speeds. It’s about 30 percent smaller than an XFP, consumes less power, and is more cost-effective. Figure 1 shows various of fibre optic transceiver types.

Passive Optical Components Provided by FS.COM

Today, passive optical network(PON) is widely used by people as a promising solution for modern access telecommunication networks. With the growing of networking, we need more creative and cost-effective PON systems which are no longer limited by the basic elements. Generally, more common passive optical components include simple fibre optic connectors, splices, couplers/splitters and fixed fibre optic attenuators. Furthermore, optical devices such as switches, variable optical attenuators, circulators, isolators and FBG(Fibre Bragg grating) sensors also are popular in a PON network structure. And this article will focus on description of optical isolators and circulators.

Optical Isolators

A optical isolator operates in a similar way to a optical circulator, but the reverse propagating lightwave is lost instead of being forwarded to a third port for output. A optical isolator is a two-port passive component which transmits light with low attenuation in only one direction. optical isolators’ main function is to reduce or eliminate back reflection and controlling noise. Generally, optical isolators are utilized as both integral and in-line components laser diode modules and optical amplifiers, and to reduce noise due to multi-path reflection in highbit-rate and analog transmission systems. The working principle of optical isolators is based on Polarizers and Faraday Rotators.

isolator

Features

  • Low insertion loss
  • Low Extinction Ratio & High Isolation
  • High stability and reliability
  • Good uniformity

Applications

  • EDFA
  • Fibre sensor
  • Fibre Optical Instrument

Optical Circulators

A fibre circulator is generally a three-port circle device designed serving as optical one-way streets to make sure that light entering any port exits from the next. Basically, direct light from port 1 to port 2, port 2 to port 3, with none going 2 to 1. However, there are other choices, for example, 4 ports(has one additional bi-directional port), 1×2 ports, 2×2 ports types in the market as the technology improves. A fibre optic circulator can be used to de-couple transmitted and received signals traveling along the same fibre (in short, the bi-directional transmission), as a kind of branching component that distributes/isolates optical power among optic fibres, depending on the direction of the lightwave propagation. The principle of optical circulators is using the Faraday rotators.
