Fiber Optics

Power over fiber system

The RLH fiber-optic link power over fiber (PoF) system from RLH Industries provides power transmission over three multimode optical fibers. It is designed to provide true isolated power to a fiber-optic-link CO side card when line sealing current or local ac power is not available. The PoF system delivers constant power and does not require backup batteries at the remote location. Using photonic technology, the PoF system eliminates the need to run conductive copper wire into a high ground potential rise (GPR) zone, and is a reliable and convenient remote-powering solution.

The PoF system comprises two units: a transmitter unit to produce the light energy, and a receiver unit to convert that energy into dc power that can run a full spectrum of RLH fiber-optic links. The PoF transmitter unit is a self-contained housing that may be 19/23 inches rack or wall-mounted and measures 3.5 in. × 13 in. × 11 in. It operates from a 24 Vdc to 56 Vdc power source, and LED and LCD indicators located on the front panel report system status and operation. The transmitter unit provides the light energy required for the receiver unit over two fiber strands. A third feedback fiber is used for system-diganostics, and to control and monitor the receiver unit.

The PoF receiver unit is a standard RLH single card form factor (7 in. × 4 in. × 1 in.) unit, and may be installed into any RLH fiber-optic link card housing. The receiver has two fiber ST photovoltaic power receivers that convert the laser light into electrical energy, and a single fiber ST transmitter for monitoring and safety shut-offs in the event of a break in fiber continuity. The PoF receiver provides 24 Vdc up to 20 mA (0.5 W). For higher power or voltage applications, multiple receivers can be connected in series or parallel.

Medical Electronics

Implantable-grade radio chip

The ZL70101 transceiver chip from Zarlink Semiconductor is an ultralow-power RF system-on-a-chip solution for use in implanted medical devices, programmers, and monitoring base stations. Building on Zarlink's MICS technology platform, the chip delivers high data rates, low power consumption and unique wake-up circuitry. Previous home-health monitoring systems required the patient to accurately position an inductive wand over the implanted device. In comparison, using MICS technology, patient health and implanted device performance data can be stored in the implanted medical device's memory and wirelessly transmitted to a base station, without requiring patient intervention. If a problem is detected, the physician will schedule a patient follow-up visit where the two-way RF link can be used to interrogate and adjust implanted device performance.

During surgery to implant medical devices, the longer operating range of the ZL70101 chip allows the base station/programmer to be located outside the sterile environment. This potentially shortens surgery times and reduces healthcare costs, as programming equipment does not have to be sterilized for use in the operating room.

The ZL70101 transceiver also incorporates a unique “wake-up” receiver that allows the integrated circuit to operate in a 250 nA sleep mode. Communication is then initiated using a specially coded wake-up signal from the base station transmitter. When in full operation the ZL70101 typically consumes 5 mA of supply current.

The ZL70101 transceiver chip is available as implantable-grade wire-bondable die or in a 48-pin QFN package for the non-implanted base station applications. The chip is fully supported by a reference system and application development kit.
