HALO® Announces the First IEEE802.3 Compliant 25G/40G Isolation Transformer for 25G and 40G Ethernet Applications

Santa Clara, California (May 6, 2021) – HALO Electronics Inc., a leading supplier of Ethernet Transformers, today announced the preliminary release of the industry’s first commercially available IEEE802.3bq compliant high-speed transformers.

Utilizing the UWBX patent pending technology, HALO® has been able to achieve the high-speed performance needed to meet the OCL, Cross Talk, Insertion Loss, Return Loss and CDMR performance required for a fully compliant 25G or 40G Ethernet port over copper cables. This UL recognized product is available for evaluation under non-disclosure agreement (NDA) effective immediately.

To read more about the unique relationship between HALO and UWBX please see the “High Speed Data Transformer Technology” press release dated January 21st, 2020.

This same proprietary transformer technology will be used to develop many ultra- high frequency galvanic isolation transformer products, which were not possible in the past, using traditional transformer construction techniques.

HALO Electronics, Inc. has been a technology leader in the communications industry since its inception in 1991. This technology investment expands HALO’s leadership role in the communications industry.

HALO® Electronics Announces New Series of 2.5G/5G Multi- Gigabit Discrete Ethernet Isolation Modules

SANTA CLARA, CA, June 4, 2018 – HALO Electronics, a global supplier of FastJack™ integrated Ethernet RJ45 connectors and discrete transformers, announced today its full line of 2.5G and 5G Ethernet transformers to address the increasing data rates of enterprise networking equipment and the higher bandwidth requirements of wireless access points.

The 2.5G/5G data rates are an important intermediary step between the 1G and 10G data rates; offering increased data transfer over 1G using existing cable installs as well as lower power consumption per port when compared to 10G.

NZ and NZ5 packageHALO’s 2.5G/5G transformers are available in two packages. The NZ/NZ5 industry standard packages are available in standard temperature and extended temperature versions with PoE, PoE+,and 4PPoE (+90W) capabilities.

In addition to the NZ/NZ5 package, HALO has announced the Nano2.5G series of miniature transformers. The Nano2.5G parts are available in PoE, PoE+, and 4PPoE (60W) options.

Product Highlights:

  • Standard and Extended Temperature Ranges
  • UL Certified
  • IEEE802.3 Compliant
  • PoE/PoE+/4PPoE Capable
  • Smallest 2.5G Footprint

The 2.5G/5G transformers are available through HALO’s franchised distributor partners. Production lead-time is stock to eight (8) to twelve (12) weeks.
