Chromis Fiberoptics Targets Resi Market with Plastic Optical Fiber

Long-time OEM Chromis Fiberoptics moves to the forefront with its own branded GigaPOF active optical cables with tight bend radius and 100lb pull strength.

Integrators may not be familiar with the name Chromis Fiberoptics, but chances are they have already used one of the company’s cables.

The Warren, N.J.-based company has been an OEM supplier since 2012 for several major brands serving the custom integration and consumer markets, including a leading well-known Korea-based video company.

Originally spun out of AT&T’s Bell Labs, Chromis is now breaking out of the shadows with its own brand of active optical cables for both HDMI and DisplayPort targeting the residential and commercial A/V channels.

"We now want to bring greater awareness to our technology,” says Frank Graziano, CEO.  The technology he is referencing is the company’s patented Monolithic GigaPOF (Polymer Optical Fiber) Ribbon, which is made using a graded index polymer fiber instead of glass. The company’s patented process allows for extruded polymer optical fiber with a low graded index profile, providing high bandwidth and low attenuation.

In all, the company says it has invested more than $14 million to develop the GigaPOF technology, and it touts 15 patents in all.

“POF can be tied into a tight knot and will not break and will still transmit signals."
— Dr. Whitney White, Chromis Fiberoptics

Certain types of polymer fiber are primarily used to carry lower bandwidth signals of 100Mbps or less in applications such as automobiles.  For clarification, traditional PMMA (acrylic) fiber is comprised of a core with fluorinated polymers as the cladding material. Those fibers are not used in active optical cables because of the low bandwidth. But since the late 1990s, according to Wikipedia, much higher performance graded-index (GI-POF) fiber based on amorphous fluoropolymer (polyperfluoro-butenylvinyl ether) has begun to appear in the marketplace. This is the high-bandwidth, low-attenuation graded-index POF made by Chromis and used in its active optical cables. It is completely different stuff compared to PMMA POF. Polymer optical fibers are typically manufactured using extrusion, in contrast to the method of pulling used for glass fibers. 

Polymer fiber cannot carry signals as far as glass, with a general limitation of less than 100 meters. But that distance limitation is not usually a problem in residential applications that integrators commonly encounter, notes Graziano.

According to Dr. Whitney White, president and CTO, the polymer has one big advantage over glass fiber…its durability.

“GigaPOF can be tied into a tight knot and will not break and will still transmit signals,” he says. “Glass fiber can fracture and has a small bend radius.” Chromis touts its POF cable having a bend radius of 0.2 inches (5mm), and the ability to withstand a pull strength of more than 100 pounds.

Moreover, it says polymer is immune to static fatigue because the molecules can "creep past each other" over time, relaxing strain.

“Also GigaPOF is compatible with lots of products. One of our key differentiators is that we do lots of compatibility testing,” adds White.

6 Different Chromis Lines

Chromis is hitting the market with several different series of pre-terminated GigaPOF cables, including its:

  • Procerus4K Series DPL-certified plenum-rated HDMI 2.0 cables in lengths of 1m, 2m, 3m, 5m, 7m and 10m and capable of carrying 18Gbps 4K@60Hz 4:4:4 HDR.
  • Pinnacle4K Series HDMI 2.0 cables ranging from 1 meter to 10 meters and capable of carrying 18Gbps 4K@60Hz 4:4:4 HDR.
  • Salus4K Series plenum-rated HDMI for runs of 10 meters to 50 meters at 18Gbps 4K@60Hz 4:4:4 HDR.
  • Reference Series HDMI 1.4 cable in lengths of 10m to 100m.
  • Amovilis Series Detachable Plenum HDMI in lengths from 10 meters to 30 meters. The pre-attached HDMI D connector is 7.8mm W x 5.3mm H. 
  • DisplayPort 1.2 Series that can carry 4 channels at 5.4Gbps each in lengths ranging from 7.5 meter to 30 meters. 

Because the cables are pre-terminated, there is reduced labor in the field doing terminations.

"Fiber is just a much better solution. Fiber will simplify an integrator’s life.”
— Frank Graziano, Chromis Fiberoptics

“We haven’t really pursued the non-terminated cable market,” says Graziano, noting that the varying lengths Chromis supplies handle “99 percent of the applications” installers will encounter. 

But what about pulling an active cable through a tight conduit? Chromis’s HDMI connector is detachable, reducing the remaining connector to just 7.5mm. The company recommends installers use a pulling sock in the field.

Regarding cost, Graziano says Chromis will be competitive.

“There is always someone cheaper, especially with so many products from China, many of which get government subsidies. We are competitive with other high-end solutions and when you include reduced labor from not having to terminate in the field we are the same,” he says.

For integrators still debating the move to fiber from copper, Graziano says. “Copper is very limited at higher data rates unless it gets a lot fatter. Fiber is just a much better solution. Fiber will simplify an integrator’s life.”

The company is building out its distribution channel now for the custom installation market, having already engaged partners such as Eric Bodley’s Future Ready Solutions. Graziano says Chromis will use both reps and distributors, depending on the market.

Very cool looking product line, but unless their dealer cost is much lower, I am not seeing the reason to use their products over Celerity’s DFO.  DFO has been fairly affordable and reliable.
