Single-mode Attenuator Designed for Technicians in the Field 

Simple-to-Use - Precise thumbwheel control facilitates one handed operation freeing technicians to monitor downstream equipment. Selecting viewable wavelengths from the calibrated FTTX wavelengths simplifies test setup and reduces potential for technician error.

Fast Power Up and zero warm-up time reduce test time.
FTTX Ready - Calibrated at 1310, 1490, 1550, and 1625 nm. Measurements traceable to international standards for reliable accuracy.
Rugged - The VOA6-SM durable package is designed to meet the challenges of field work. Its shock resistant design and splash resistant controls provide dependable performance for technicians on the go.
Offering 60 dB attenuation range, low insertion loss, and high return loss, the NOYES VOA6-SM from NOYES is designed for applications such as Bit Error Rate (BER) testing and measuring system tolerance to signal attenuation.
The VOA6-SM is powered by a rechargeable Li-Ion battery or an AC power adapter.  Battery charger and global power adapter included.

Buildout Attenuator Selection

Use VOA6-SM to quickly measure system headroom and deternine attenuation level needed to match receivers to networks.  Makes on location selection of fixed buildout attenuators fast and efficient.
