Fiber Evolution – Micro Cables

As 200𝜇m fiber is becoming increasingly commonplace, so are increased fiber counts in micro cables

Due to increasing usage of video related applications and the need of transportation of high amounts of Data in modern networks the demand for bandwidth and speed continues to increase. The only way to fulfill that demand is applying fiber in the future proof networks.

There are two trends in deploying fiber networks. Increasing low-count fibers cables to connect single users/subscribers or buildings. To distribute large volumes of information we see an increasing need for very high-count fiber cables. The average numbers of fibers in these high-count cables continue to increase. Cables featuring over 500 fibers in one cable are becoming increasingly common.

Adding more fibers in the cable and scaling up the fiber cable design is a common practice. However, for cables blown into ducts this up-scaling is not an option, because of limited duct space. Ducts are deployed in advance of the cable and the dimensions are fixed.

The micro-cables, a cable design with smaller dimensions than typically used, offer an economic advantage. To reduce the fiber cable diameter cable manufacturers started to apply 200 𝜇m instead of 250 𝜇m coated fibers. By using the smaller fiber, a 36% smaller design is the outcome.

Fig. 1 – Reducing cable size with 36%
Fig-2 – Doubling the number of fibers in a tube.










Comparing as an example a 288-fiber count cable can be reduced from 14 mm OD to 9.6 mm. In combination with the G.657 fiber and applying a micro bend –resistant coating the packing density in a tube can be higher with the 200 𝜇m fiber.

In fact, using this fiber the fiber-count for a given cable design can be doubled.

How To Decide What Goes Into A Fiber Prep Kit


Kit configuration starts with our marketing department, our staff of engineers and our sales team. Usually it’s the sales team up first explaining the need for a kit for a specific customer or they had an inspiration or a germ of an idea from a tech in the field saying he wished he had a selection of tools in an all-in-one kit. Ideas can originate just about anywhere. All suggestions are evaluated, and one of the first questions posed is there a market for this kit and will anyone care (translation, will anyone buy it)?

Kevin Costner starred in the movie, Field of Dreams. And a voice over kept saying, “if you build it they will come.” We ask, if you build it will the customers come. In the case of fiber prep tools and the need for a kit our marketing department conducted extensive research and found such a need, and with the breadth of line, Jonard Tools was positioned to fill it.

Because fiber is ubiquitous and more and more is being installed every day, the need for the proper tools for installation and maintenance continues to grow; therefore, the need for fiber prep tools continues to grow. So, the question then becomes, what goes into a fiber prep kit?

Jonard Tools has a number of Fiber Prep Kits in the line including the TK-120 Fiber Prep Kit and the TK-150 Fiber Prep Kit with Connector Cleaner, Fiber Cleaver & Visual Fault Locator. The TK-150 features all of the same tools as the TK-120 plus the VFL-150 Visual Fault Locator, FCC-250 Fiber Connector Cleaner and the FC-220 Fiber Cleaver. These kits have been on the market for a little over a year and can already be found in use around the world. But who decided what to put in the kits and how was that decision made?

Cable StrippersLooking at the tools contained in the TK-120 and the function of each explains how and why they were chosen. To start there are three cable stripping tools, the CST-1900 Round Cable Stripper, CSR-1575 Cable Strip & Ring Tool, and the FOD-2000 Fiber Optic Drop Cable Slitter. These tools allow you to open cable jackets and buffer tubes to gain access to the fiber.

MS-6 Blog 02Along the same line is the MS-6 Mid Span Slitter. This patent pending tool allows the tech to gain access to a fiber mid span for either a repair or connectorizing a fiber.

Every kit needs a fiber stripper and Jonard Tools manufactures the JIC-375 Fiber Optic Stripper Three Hole…THE tool for stripping fiber optic cable. And if you are exposing the inner workings of the cable you are bound to encounter Kevlar – a very tough material. A standard scissor would last a week before breaking so you need the JIC-186 Ergonomic Fiber Optic Kevlar Cutter…a tough resilient scissor specifically designed to deal with materials as tough as Kevlar.

Rounding out the kit you need a flashlight like the FL-2000, a screwdriver like the SD-61 Multi Bit Screwdriver for opening panel boxes, FW-5 fiber wipes for cleaning the fiber and a couple of pliers. We included the JIC-2288 Diagonal Cutter Pliers for use as the name implies – for cutting cables, and the JIC-842 Telecom Long Nose Pliers for grabbing or pulling cables. Now add the rugged H-90 21 Pocket Tool Case and you have the perfect kit…and that is the genesis of the fiber Prep kit.

Industry Evolution since 1958

In 1958 the telecommunications world was a much different place than it is today. Back then you didn’t own your phone you leased it from the phone company. Party lines were fairly common and in rural areas there was a community phone located in a general store or post office or other public gathering place. If something was wrong, you called the telephone company and they came out and repaired the phone. Technicians’ tools were much different too. Back then screwdrivers, needle nose pliers, diagonal cutters, a wiggy or kickmeter, butt set, and a trusty can wrench were the tools of a telephone tech. Today phones are private property, party lines and community phones are all but extinct, and the technician’s tools bag have many more items in it. The convergence of Voice, Data and Video (VDV) has forced the technician to become much more sophisticated, and the tools he uses have changed as well (although some tools such as the Can Wrench are still true workhorses).

Entering into the 60’s the first touch tone phones were introduced.  The changeover from the letter number system to all numbers was in full swing and things were starting to get more sophisticated. However, telephony was still connected through the trusty twisted pair. The late seventies and eighties brought huge change to the telecom industry. The telephone company monopoly was broken up and you no longer needed to get your physical phone from the phone company. The connections on the old main frames were starting to switch from wire wrap to punch down and digital started to play a more important role as the switching technology changed over from relay to electronic.  The phone system was still separate and run on twisted pair technology. Things were about to change.


In the mid 1990’s the internet started to become more mainstream. Connecting to the internet required the use of a modem and a telephone line and ˗ compared with the data speeds of today ˗ was incredibly slow .  However many of the tools used back in the 50’s were still being used. You still need your handy can wrench, diagonal cutter and needle nose pliers. The test equipment required is a different story. While still needing a handy butt set you now needed test equipment with the ability to check data accuracy as well as data speed.

article.large_rectThe 2000’s brought about faster and faster change; we no longer talk telephony, its VDV, its IP telephony, and now cable providers offer telephone service. The twisted pair is being replaced with fiber optic cable to the home (FTTH) or fiber to the neighborhood (FTTN). Most technicians are now armed with very high-tech pieces of test equipment, and other tools such as fiber optic strippers, compression tools for cable, and even satellite finders for those using satellite TV service.

In the next decade where will communications go from here? We see the convergence of VDV and the next generation of connectivity in process, with fiber and satellite.  Add in cellular telephony and the role it plays in communications and you can see that the future is filled with endless possibilities. While many of the tools have changed and advanced I can think of three that will remain; the trusty can wrench, the diagonal cutter, and the needle nose plier.

Life Cycle of the Can Wrench

Jonard Tools Can Wrenches
Jonard Tools Can Wrenches

The origin of this unique tool traces back to the early 1950s. With the telecom industry ramping up, and new installations exploding on the scene, the requirement to protect connections from foul play, from the elements and from curios animals or insects, connections were terminated in service boxes. These boxes were in turn protected by a uniquely designed lock. Well, if you have a lock, you need a key. But not just any key, one that was secure from tampering and at the same time convenient for the technician who would service the installation.

That lead to the advent of the can socket, which locked the box yet was easily unlocked with a can socket wrench. Designed by the world renowned Bell Labs, the can socket wrench was born. It was spring loaded, hex shaped and when collapsed revealed a screwdriver tip inside. It was designated by Bell Labs with the part number 216B (the Jonard M-216B was first manufactured in 1961).

M-216B Can Socket

Years later the original M-216B design was made obsolete when he binding post no longer required a screwdriver tip.

In keeping up with the times, our first iteration of this new design was the M-216C/HX (first manufactured in 1984). The wrench was thin handled (5/8″ diameter) with hex ends. It was further improved when Bellsouth reached out to us to solve a problem with can sockets being damaged from overzealous techs putting too much torque on the wrenches. It seems that if you use an adjustable wrench on the hex ends the predictable result followed…destruction of the lock.

M-216C/RX Can Wrench, Standard Round

The M-216C/RX was born (1992). A thin handled tool (5/8″) without a hex end to prevent the attachment of any tools that could increase torque beyond one’s innate hand strength.

M-216EX M-216CREX

In 1998 Verizon came to Jonard Tools with a new request, design an ergonomic can wrench without a hex socket. The M-216C/REX was born and it is still in use today.

Time marches on, and as with everything in life there are always improvements to be made. The 5/8″ diameter wrench was the precursor to a more ergonomic version – a 1″ diameter wrench designated M-216C/EX (first manufactured for AT&T in 2001), a more robust design to facilitate greater torque. This design helped with old or frozen locks and eased the strain on wrists and hands.

M-216CKIT Can Wrench Security Key Kit

In 2003 AT&T added a new requirement to their can wrenches – a wire stripper. That lead to the development of the M-216CS22 Can Wrench with a built in wire stripper supporting two slots, one for 22 AWG wire and the other for the outside jacket of a four wire “quad.”

Several years later the Jonard Tools R&D team developed a security key insert (SK-51632) that fit in the 3/8″ side of a can wrench, which allowed the tech to keep the 7/16″ side continuously available. AT&T had come to us with this requirement and the finished tools was delivered in 2005. This insert is used for either a 5/16″ or 5/32″ hex security screw for SLC cabinets and for most network interface boxes.

SSK-876 Star Key Can Wrench Kit

In 2014 we delivered a special can wrench kit to Comcast. The SSK-876 is a three component kit including a blue handled can wrench with two 7/16″ hex sockets at either end plus two slam lock star keys with LS, LB, LG & LC star patterns. Each key has two patterns (one at either end) providing access by reversing the key in the can wrench.

Always looking to improve and innovate, Jonard Tools is at the forefront of design for the broadband industry.

Small, simple and efficient. Jonard Tools MS-6 Mid Span Slitter.

What started as a prototype dreamed up by our engineering team, is now a remarkably unique tool (patent pending) with endless use cases. Originally intended to be used exclusively on fiber optic cable, tech professionals found it suitable for many other applications. Regardless of your level of expertise: from industry professionals running speaker wire in a pro audio recording studio; to ambitious DIYers wiring a new home theater, the MS-6 gets the job done effortlessly.

A review of the tool from an end user put it best: “Small, simple and efficient.”

Small enough to fit into any tool box, it measures only 1 5/8″ (H) x 1 1/8″ (W) x 3/4″ (D).

Simple to use:

  • Select the groove that matches your wire size.
  • Place the fiber in the groove.
  • Close the tool (make sure the lock is engaged).
  • Pull the tool following the arrow.

MS-6 Blog 06

As for the tool’s efficiency, it just works every time. And in the event the blades begin to dull they are easily replaced (which, by the way, is a feature unique to MS-6).

All in all, MS-6 is a must have item for all Fiber Techs and any do-it-yourselfers as well. The price makes this an affordable gift idea.
