Chromis Platform Fiber Technologies
Perfluorinated POF
graded-index fiber
10-40 Gb/s, 30-100 mtrs
850 nm lasers
highest performance
higher per-meter cost
succeeds by termination advantages
PMMA POF
step-index fiber
<200 Mb/s
up to 100 meters
cut-and plug
low performance
low cost
residential industrial
data center consumer
(mostly AOC)
Chlorinated POF
10+ Gb/s
up to 10 meters
780 nm lasers
medium performance
very low cost
same termination advantages
residential industrial
Step-Index PMMA POF
Even at 100 Mb/s, POF has many advantages vs copper, wireless
• No electromagnetic interference • Smaller (2X) and lighter (3X) than Cat 5
• No professional installation needed – simpler than Cat 5 • Non-conducting – no grounding needed, runs in power conduit
• Reliability – historically ~80% less downtime with optics
Ultimate in simplicity – cut and plug in like speaker wire
Chromis PMMA Cables
white outer sheath1.0 mm PMMA Fiberblack inner sheath• Industry-standard sizes
2.2 mm simplex 2.2 x 4.4 mm duplex zipcord
• Light-blocking inner sheath • Highly flame-retardant plenum (OFNP) UL-listed with zero-halogen or PVC
• Cable cost less than Cat 5
• 70oC temperature performance
Cables with 85oC fibers also available for industrial uses

Copper has problems beyond ~few meters and 10 Gb/s Optical solutions superior in size, weight, reliability and durability AOC’s needed for reliable consumer interface A big opportunity for POF AOC, but only at low, low prices.
Connectorless Transceiver Concept
• VCSEL-based, 850 nm (can use CW source for visible red tracer)
• Alignment sleeve (~765 µm ID) aligns POF with active devices
• 75 µm fiber core diameter ⇒ low cable cost
• Takes “cut and plug” termination from 100 Mb/s to 1 Gb/s and 10 Gb/s
Key cost reducer: Connectorless termination
• zero piece part cost
• secure with clamp or with adhesive
• large fiber OD enables standard lens designs
Key cost reducer: simple, automated termination
• Diamond blade cutting tool
• bare cable end or with connectors
• < 10 second cycle time
• Smooth, clean, endface, negligible loss
• Terminate multiple fibers simultaneously
Fiber termination cost ~zero
Many customers just use a razor blade
GigaPOF Ribbons for AOC and Backplane
• Ribbon terminates as a single unit – usually with just a razor blade
• External surfaces used for alignment – no stripping
Passively Aligned Ribbon OSA’s
Termination Process
Mill entire cable end
Strip sheath at end
Insert entire ribbon into receptacle
Cure UV adhesive
Finisar Laserwire Connector-free OSA with GigaPOF®

Allows large cores (200-500 µm) for field termination Lower material cost than perfluorinated materials
Higher NA (0.30 vs. 0.19)
Very attractive for residential and industrial gigabit networks
