Versa Transceiver Technologies Make Multi-Cable Networks Click

Versa Transceiver Technologies Make Multi-Cable Networks Click

Network installers and IT administrators continue the move toward green. To recapture and use existing cabling infrastructures, and allocate the money in their budgets to purchase better devices, savvy thinkers are opting to deploy transceivers. As you probably already know, a network transceiver spans the gap between Ethernet and coax, Ethernet and fiber, and between coax and fiber. It also links single-mode and multi-mode cabling deployments. This article is going to pull together the pieces for a quick view resource. It’s not rocket science, but it is sophisticated enough where a one-stop reference might make life easier.

What is SPF+?

Small Form-factor Pluggable PLUS (SFP+) is a small, second-generation optical transceiver used to convert back and forth between optical and electrical signals. They plug into the SFP port of a network switch. It is used to connect to Fiber Channel and Gigabit Ethernet (GbE) optical fiber cables together in one network. They are plug-and-play devices following the trend toward simplification. They are part of the GBIC transceiver family. They are specificially designed to support 10G performance.

What is the difference between SFP and SFP+?

The primary difference between the two technologies is data rate. The SFP maxes out at 5 Gbps, while the SFP+ is designed to reach 10 Gbps. Both are used in applications for both telecom and datacom.Impedance is better in the plus design.

Why is the faster 10 Gbps speed better?

At present, 1000BASE technologies are still in the 2.5 Gbps to 5 Gbps range, so no apparent difference. Over the next 5 years, though, expect devices to start cracking through that ceiling. The Internet, however, is a different matter.

What is 10 Gbps Internet?

Does 10 Gbps Internet even exist? Blame it on Bitcoin and the mining community because not everyone can afford to pay $300 a month for this kind of service. According to the media outlet Motherboard, ISPs began to offer this type of service sometime around 2016. One man with a radiology based business in Chattanooga TN was one of the first to purchase it.Internet Speed TestTest Your Internet Speed.G.Fast and VDSL2 are going to be the technologies that bring higher broadband speeds into reality. Stay tuned.

What is the difference between an SFP and a GBIC?GBIC vs SFP

Gigabit Interface Converters (GBIC) and SFP, their miniature cousins, are both optical transceivers. They convert signals to and from optical and electrical forms. The perception is that SFPs are an upgrade because their smaller size allows more of them to be deployed on a single switch than the GBIC.If you already have a line card for GBICs, you can continue to fill it with GBIC compatible connections. If you don’t have a GBIC line card, then SFPs are a super-easy alternative.

What is a transceiver and what does it do?

“Transceiver” is a combination of the words transmitter and receiver, and the melding of that capability within a single housing is what you get within these devices. An optical transceiver chip transmits and receives data over fiber instead of wire. Information pulses over light beamed along transparent fibers or cables.

Cable and technology glossary

To simplify this further, here are some of the alphabetical standards and a quick view of what each of signifies.

What does the “X” in 1000BASE-X mean?

The X refers to FAST ETHERNET. Also known as IEEE 802.3z, the X refers mostly to Ethernet transmission over fiber optic cable, although shielded copper is sometimes used. One of the many benefits is the multi-directional ability that this standard provides. You can use 1000BASE-X for both single-mode and multi-mode deployments.Here are what some of the “X” combinations mean:
1000BASE NameCable Specs aka MediaDistances of up to:
CXShielded copper25 meters
KXCopper backplane1 meter
SXMulti-mode fiber/ 770 to 860 nm wavelengthFDDI 220 meters OM1 275 meters OM2 550 meters
LXMulti-mode fiber 1,270 to 1,355 nm wavelength550 meters
LXSingle-mode fiber 1,270 to 1,355 nm wavelength5 kilometers
LX10Single-mode fiber 1,260 to 1,360 nm wavelength10 kilometers
EXSingle-mode fiber 1,310 nm wavelength~ 40 kilometers
ZXSingle-mode fiber 1,550 nm wavelength~ 70 kilometers
BX10Single-mode fiber, single-strand: 1,480 to 1,500 nm downstream, 1,260 to 1,360 nm upstream10 kilometers
The information in this table comes from IEEE 802.3-2008, clause 39.

What does the “T” in 1000BASE-T mean?

1000BASE-T refers to Cat5e, Cat6, and Cat7 Ethernet cable. No surprise there. These are cables that send signals using electrical energy. The same is true for coax. An SFP is needed between Ethernet and coax on the same switch, just to be clear.More alphabet glossary, this time for “T.”
1000BASE NameCable Specs aka MediaDistances of up to:
TTwisted-pair cabling (Cat5, Cat5e, Cat6, and Cat7)100 meters1
T1Single, balanced twisted pair15 meters
TXTwisted-pair cabling (Cat6 and Cat7)100 meters1
1 These distances are stretched through the use of Ethernet Extender Kits and Injectors.

What does the “RHx” in 1000BASE-RHx mean?

1000BASE-RHX refers to optical plastic fiber.
1000BASE NameCable Specs aka MediaDistances of up to:
RHxPlastic optical fiber15-50 meters

NBC Employs Versatek SFP Media Converters to Cover Rio Olympics

NBC Sports coverage for the 2016 Olympic Games just wrapped up. No stranger to providing production work for massive events like Rio, Jim Bell (Executive Producer) and his army of technicians and journalists have inserted both themselves and their equipment right into the middle of the action for 16 consecutive days and nights.To get a sense of the enormity of the Olympics, here are some stats on this years Games:
  • 11,339 athletes
  • 207 nations
  • 41 disciplines
  • 306 events
Keep in mind, those numbers don’t include coaches, family and friends, media from 207 countries, or the tens of thousands of spectators who traveled to watch the games up close.Speaking of media, if you're curious about how many countries were broadcasting the games, here's a small sample and a link to the complete list.Olympics

Production Demands for the Olympics

Fortunately for those of us viewing from afar, this year’s games saw a big spike in overall production quality. Viewers now demand more sophisticated technology than ever before - and certainly more than they did during the last games. This heightened expectation is due in part to the outstanding coverage of the fiftieth Super Bowl hosted in San Francisco earlier this year at Levi’s® Stadium.It was during the Super bowl that CBS Sports first introduced EyeVision 360°, a revolutionary camera technology that allows viewers to see critical moments of the game in stop-action and from every angle.Not to be eclipsed by any stretch, NBC Sports made good use of the exact same technology throughout their coverage of the Olympic Games. This was particularly useful during events like diving and gymnastics, where it enabled viewers to watch frame-by-frame replays and compare details like take-offs and landings from multiple angles.The Super Bowl also introduced 5K resolution cameras and surround sound pylons on the field. These evoked a sense of “being right there” on the field for home audiences. Again, NBC Sports used similar technologies to deliver intimate moments in events like volleyball, where team members embraced between plays and cheered each other on at turning points and during tough moments.As you would assume, an increased demand for high-resolution and high-definition signals means that the connectivity requirements will be higher as well.

Equipment Set and Reset

Throughout the aggressive 16-day program, NBC deployed teams in four main centers of competition, roughly 5 miles apart.They also filmed sailing and rowing competitions in the bay. To get an idea of what that looked like logistically, here’s an overhead map of the Games.

Coverage bounced back and forth between competitions, in-studio interviews, panel discussions, and on location reports.When it comes to shooting live events, there’s no room for second takes. The stress free set and reset of cables is both critical and essential.Quick turn-around times between competitions minimized disruption for the althletes.Production crews were able to make this all happen seamlessly through the use of Media Converters. The NBC production team brought thousands of these units to Rio.Networks have been using these units sometime for NFL coverage, it only makes sense that they would employ the same effective technology to cover Rio 2016.The unit NBC used at the Olympic Games, available through PlanetechUSA, is the GT-805A. This model is a 10/100/1000 Base-T to 1000FX (SPF) Converter that connects over fiber optic cables. The production team drew power from Ethernet switches to the media converters using CAT5/CAT6 cables and an AC to DC adapters.

Why Is the GT805A SFP Media Converter So Popular?

The reason NBC Sports and the NFL prefer Versatek’s SFP Media Converters is simple: ease of use.There is no proprietary software required to run the devices. There is no firmware that needs to be constantly updated. With these SFP Media Converters, users are able to simply plug-n-play.When world records are being made, and when touchdown replays are needed—downtime or connectivity issues simply can't be afforded.Who needs the hassle or cost of other units? Not NBC anyways!
