• High Power Laser SMA905 Optical Fiber Patch Cord

  • Photonstream is focusing on optical fiber processing & AR coating over 10 years, we supply

    high reliable products to our customers.


    With the wide application of direct semi-conduct laser, the end users are looking for a

    pluggable and replaceable optical fiber jumper to adapt to the laser source. In most case of

    medical and fast solid state laser breakdown, the optical fiber patch cord connector was damaged

    while the laser source is still valid, so people would like to replace with a new optical fiber patch

    cord to restart the system, which should have good coupling efficiency and reliability for high

    power laser. Based on this market requirement, Photonstream develops this special high power

    fiber patch cord.

  • Product Introduction:

    High Power Laser SMA905 Optical Fiber Patch Cord is designed with SMA905 connectors for both ends

    and stainless steel armor with PVC shield for fiber protective in harsh environment (Figure 2). The input and output connectors could choose different ferrule designs based on different laser

    power levels and thermal conductive conditions.

       ◆  Product application     

    1) Semi-conduct diode laser coupling and delivery

    2) Solid state pump laser optical fiber tail

    3) Medical laser delivery

    4) Outdoor long distance high power laser transmission

    5) Optical test in the lab


       ◆  Product feature     

    This SMA905 high power patch cord is special designed for high power diode laser coupling

    and transmission, including following feature:

    1) The Input terminal is with cantilever ferrule SMA905 design, the fiber tip free standing and

    without epoxy, which is special for high power laser coupling and prevents burning.

    2) The fiber tip is align with ferrule end face, which is critical for optical coupling efficiency

    for different connectors. The focus lens inside the laser source is with fixed

    focusing length, every fiber tip should be arrived at the sample position to get the consistent

    optical coupling efficiency.

    3) For some fiber tip position adjustable requirement, we design a rotate holes inside the sleeve

    to turn the fiber TIP to match the focus point, which allows the connector to get maximum

    optical fiber coupling efficiency.

    4) For the output terminal, there are three type of ferrule for SMA905 connector design: the

    standard ceramic SMA905(planar tip design), the standard stainless SMA905(planar tip

    design) and the cantilever stainless design.

    5) Several colors or tube sizes for armoured shield for selection.

    6) The fiber and ferrule have a good concentricity and the fiber tip surface is under optical

    polishing and super cleanness, no contamination, no scratch and no cracks.

    7) Accept custom AR coating design, for example R<0.2% @ 808 nm±50nm.
