ULP Ethernet transceivers address heat dissipation issue

Avago Technologies has announced an ultra-low power Fast Ethernet Small Form-factor Pluggable (SFP) fibre optic transceiver module device, the AFBR-57E6APZ, designed for industrial automation, controls and networking applications. The device features a redesigned chip set for LED control, Diagnostic Monitoring Interface (DMI) and signal processing, which significantly reduces the module power dissipation.

Compared with the previous generation device, the AFBR-57E6APZ consumes 42% less in power while delivering superior electrical and optical performance, achieving 255mW (typ) and 405mW (max) over the temperature range of -40 to +85°C.

The device can link distances up to 2km using 50/125μm or 62.5/125μm multimode fibre, and is compatible with SFF-8074i and SFF-8472 MSA specifications, as well as the 100BASE-FX version of IEEE 802.3u. Robust, long-life LED technology prevents catastrophic failure of the laser like sudden death or mirror degradation.

“Fast Ethernet is widely used in industrial automation, controls and networking. As more fibre optic nodes are added to the network, cumulative heat dissipation becomes an industrial concern prompting the need for low power fibre optic transceiver solutions,” said Martin Weigert, Vice President and General Manager, Industrial Fibre Product Division, Avago. “Our ultra-low power 100BASE-FX SFP module is a solution that addresses the power issue that affects many of our industrial customers, enabling them to simplify network rack design and avoid having to use expensive cooling fans and ventilation in their systems.”

Samples and production quantities are available now through Avago’s direct sales channel and worldwide distribution partners.
