Attenuators are used to adapt the transmitted light power to the characteristics of the implanted receiver. The in-line fixed attenuators (OAF) offer excellent reliability and repeatable amount of light loss (attenuation) via a doped fiber. This results in wavelength independent and stable attenuation values for typical wavelength bands used in telecommunication applications (1260-1360 and 1460-1580 nm). They are suitable for optical power up to 20dBm.
The MIL-83526 DM connector is the most recent product developed for harsh environments. It incorporates four termini based on DIAMOND's two-component ferrules, assembled with our Active Core Alignment (ACA) process for unparalleled optical performances. This connector is available for MM, SM (PC/APC) and small core single mode fibre, polarization-maintaining (PM) fibre, and other specialty fibre types. Furthermore, this connector can also include electrical contacts for hybrid E/O applications.
