Diamond PS connector systems

Diamond PS connector systems are designed for high power applications up to 3 Watts optical power for SM fibers. These have been developed to support the continuous rise of higher bitrates and longer transmission distances within DWDM technology.


Diamond PS connectors are based on contacted expanded beam technology; where a section of graded index fiber is spliced as a collimating lens, which enlarges the beam diameter and reduces power density at the connector interface.Using Diamond Active Core Alignment (ACA) technology, we can achieve unrivaled low IL performance for the PS technology by aligning the fiber exit angle instead of the core eccentricity as Diamond usually does on SM fiber. This technology is applicable to most connectors interfaces, but due to safety issues Diamond suggests to use it on E-2000™ and F-3000™ connectors with integrated metal protection caps and shutters.


All of the features, users have come to expect from the E-2000™, F-3000™ and DMI family, are available on the PS version.


Optical Interface

The recent trend to increase power in optical transmission systems due to traffic increase and the transition to 100G networks results in a higher power density on the optical interface. Standard singlemode connectors become susceptible to heat related damage when power density reaches 0.3MW/cm2.


DIAMOND offers the PS optical interface which expands the MFD of a SM fiber by splicing a GRIN lens at the extremity. The MFD at the end of the connector is thus expanded by a factor of 4, increasing the contact surface by a factor of about 16. As a result the heat issues decrease but cleanliness of the connectors and mating adapters is still important.


Using our Active Core Alignment (ACA) technology, Diamond can achieve unrivaled low IL performance for the PS technology by aligning the fiber exit angle instead of the core eccentricity as Diamond usually does on SM fiber.


This Optical Interface is applicable to most connectors interfaces, but due to safety issues Diamond suggests the PS optical interface on E-2000™ and F-3000™ The DMI connector interface is also available for board level terminations.
