E-Tube™

Unique dielectric waveguide, RF & PAM SoCs for the terabit era

E-TubeTM is a groundbreaking technology that will eliminate the need for expensive and power-hungry optics and bulky copper cables.

PT-S20032 SFP56 Active E-TubeTM Cable

  • Single channel 56Gbps/PAM4
  • E-TubeTM transceiver
  • Up to 5m
  • Plug and Play
  • Low power consumption (<1W)
  • Lighter than copper cable
The PT-S20032 E-TubeTM is a single 56 Gbps Small Form-factor, Pluggable (SFP) E-TubeTM module that conforms to 50G BASE-SR4 Ethernet. It is a 56Gbps PAM4 lane that can operate up to 5 meters whileachieving good BER performance and maintaining low power dissipationand low cost. It achieves an unprecedented level of performance in terms of bandwidth-per-carrier frequency, power, and density without requiring a precision manufacturing process unlike conventional optical solutions. E-TubeTM replaces conventional copper conductor-based and optical interconnects in high-speed, short-reach communication links such as intra-server-rack-connections.

PT- Q2282240 QSFP28 Active E-TubeTM Cable

  • Quad channel 100Gbps NRZ
  • E-Tube transceiver
  • Up to 5m
  • Plug and Play
  • Low power consumption (<3.2W)
  • Lighter than copper cable
The PT- Q2282240 E-TubeTM is a parallel 100 Gbps Qual Small Form-factor, Pluggable (QSFP) E-TubeTM module that conforms to 28GBASE-SR4 Ethernet. It is four 25.78Gbps NRZ lanes that can operate up to 5 meters while achieving good BER performance and maintaining low power dissipation and low cost. It achieves an unprecedented level of performance in terms of bandwidth-per-carrier frequency, power, and density without requiring a precision manufacturing process unlike conventional optical solutions. E-TubeTM replaces conventional copper conductor-based and optical interconnects in high-speed, short-reach communication links such as intra-server-rack-connections.

UHD TV interface

  • Display technology has been making rapid progress and it’s becoming thinner and more clear.
  • The E-TubeTM solution enables high-speed video data transmission with a low-power, low-cost, and highly reliable consumer interconnect for ultra-slim UHD TV interfaces.

How E-TubeTM works

01

(Copper) Conductor has been used for the last 150 years

  • cost and power efficient
  • low electrical loss

02

Lossy trace at high-frequency

  • Free electrons are localized at the surface
  • Metallic interconnect is very lossy at high-frequency
  • Metallic connection is not good for high data rate signaling

03

E-TubeTM

  • no skin effect (no free electron)
  • low channel loss for high data rate signaling (56Gbps+ per port)
  • very low cost, similar to a plastic straw
  • suitable for high volume market needs
  • vertical coupling; small footprint allows high port density
  • no crosstalk

04

Chip-to-chip interconnect with clad-dielectric waveguides

  • E-TubeTM technology is composed of:
  1. Clad dielectric waveguide cable
  2. Low-power transceiver IC
  3. Low cost / high density connector
  • Reach can be extended with more power and E-TubeTM area
