66 Block - Telephone Wiring Block & Accessories

A 66 block (or M1-50) is a type of punchdown block used to connect sets of wires in a telephone system. 66 blocks are designed to terminate 22 through 26 AWG solid copper wire. Discount-Low-Voltage.com carries a complete line of 66 blocks, prewired 66 blocks, and 66 block accessories. In today's video, we take a look at the 66 block and a few of the 66 block accessories we have available. Enjoy

Here is a picture a customer sent us of a recent job he did.

Notice how clean everything looks due to the use of backboards and spools. In my opinion, every 66 block install should be done this way. Take a look at How NOT to install 66 blocks and some crazy data center wiring pictures. Have some pictures of a job you recently did? Or a job site you went to that looked like a mess? Send them to k.atkins@discount-low-voltage.com and we'll feature them in our next blog or add them to the website.

What's the Difference Between Loose Tube Fiber and Tight Buffer Fiber



Tight Buffer Fiber


Tight-buffered cables often are used for intra-building, risers, general building and plenum applications. Tight buffer fiber contains a thick coating of a plastic-type material which is applied directly to the outside of each individual fiber. Loose-Tube fiber optic cables are typically used for outside-plant installation in aerial, duct and direct-buried applications. Loose-tube fiber contains multiple strands of fiber in a single jacket. Since the fibers are "loose" inside the jacket, outside forces are less likely to reach the fibers. This makes it the more durable option of the two.

Loose-Tube Cable

Loose-tube fiber generally consists of 12 strands of fiber, but can range anywhere as low as 6, all the way up to 244 strands. Loose tube cables can be either dielectric or optionally armored. The modular buffer-tube design permits easy drop-off of groups of fibers at intermediate points, without interfering with other protected buffer tubes being routed to other locations. The loose-tube design also helps in the identification and administration of fibers in the system.

In a loose-tube cable design, color-coded plastic buffer tubes house and protect optical fibers. An optional gel filling compound impedes water penetration. Excess fiber length (relative to buffer tube length) insulates fibers from stresses of installation and environmental loading. Buffer tubes are stranded around a dielectric or steel central member, which serves as an anti-buckling element.
The cable core, typically uses aramid yarn, as the primary tensile strength member. The outer polyethylene jacket is extruded over the core. If armoring is required, a corrugated steel tape is formed around a single jacketed cable with an additional jacket extruded over the armor.

Here's a video example of a loose tube fiber from our YouTube Channel 

Tight-Buffered Cable

Single-fiber tight-buffered cables are used as pigtails, patch cords and jumpers to terminate loose-tube cables directly into opto-electronic transmitters, receivers and other active and passive components.Multi-fiber tight-buffered cables also are available and are used primarily for alternative routing and handling flexibility and ease within buildings.With tight-buffered cable designs, the buffering material is in direct contact with the fiber. This design is suited for "jumper cables" which connect outside plant cables to terminal equipment, and also for linking various devices in a premises network.

The tight-buffered design provides a rugged cable structure to protect individual fibers during handling, routing and connectorization. Yarn strength members keep the tensile load away from the fiber.

As with loose-tube cables, optical specifications for tight-buffered cables also should include the maximum performance of all fibers over the operating temperature range and life of the cable. Averages should not be acceptable.

Here's an example of a tight buffered cable from our channel.

Hope we've given you some good information on what you might need. For other pointers on termination, installation, search our blog and YouTube channel or you can contact Mercy Salinas about fiber optics at 888-797-3697 extension 232. You could also comment below, thanks!

FAST Fiber Connector FAQ

AFL Telecommunications FAST Fiber Connectors FAQ

Q: What is the index of refraction over temperature?
A: The refractive index is 1.469 at 25degC, with a thermo-optic coefficient of less than 4.0×10-4/degC.

Q: How do you prevent the gel from drying out inside of the connector?
A: The gel has a low evaporation rate. There is data inside the document that shows the % weight reduction of the gel over time.

Q: What prevents the gel from migrating away from the fiber?
A: The upper body of the mechanical splice part is designed such that the surface area clamping onto bare fiber is minimized, thereby preventing the gel from migrating away from the splice point.

 Q: What fusion splicer will you need to use the FuseConnect connector?
A: It will work with FSM-11-S, 11-R, 17-R, 17-S-FH, 50-R, 18-R, 18-S, 60-S, and 60-R.

Q: Why does the external tube heater take longer to heat the protective sleeve?
A: The heater takes longer because the FuseConnect protective sleeve is larger than a standard splice sleeve and has an inner sleeve and outer sleeve. The inner sleeve protects the splice. The outer sleeve protects the inner sleeve and captures the cable or fiber and connector body to obtain the pull strength.

Q: What is the loss at the splicing point and connector?
A: The typical loss at the splice point is 0.01 dB and 0.20 dB at the connector.

Q: What type of FuseConnect connectors are available?
A: Currently we only offer single-mode and multimode (50µm, 50µm 10GIG, and 62.5µm) SC/UPC, SC/APC, SC/PC, LC/UPC, and LC/PC in 3mm, 2mm, and 900µm boot.

Q: Do you need to clean the fiber stub at the end of the FuseConnect connector?
A: No, you do not need to clean the fiber because it is clean from the factory.

Q: Why does the protective sleeve not shrink onto the 900µm fiber?
A: Check the mode on the FuseConnect heater and make sure it is set on MODE 2.

Q: How many splices can be executed using the battery-operated FSM-18 or FSM-60 series with the FuseConnect heater power cord attached?
A: Up to 50+ splices per fully charged battery for the FSM-18 or FSM-60 series.

Q: What are the 2mm or 3mm cable clamps use for?
A: The 2mm or 3mm clamps are use to clamp onto the 900µm fiber inside the cable jacket. The clamps prevent the 900µm fiber from pistoning out of the jacket.

Q: Can you terminate the FuseConnect connector onto a Fanout or Breakout kit?
A: Yes, we recommend using our Fanout kit. It will not melt the 900µm furcation tube in our external heater.

Q: Why would the FuseConnect connector melt back to a round end face during the termination process?
A: There are 2 possibilities, one is that the arc power (cleaning or splicing) is too strong; and the other is the insufficient compression force of fibers (the holder may be caught somewhere such that it cannot move smoothly forward).
