    Frequently Asked Questions


    What does the suffix ‘-C’ mean in our part numbers?

    We are frequently asked what the suffix ‘-C’ means in our part numbers.

    Simply put, the ‘-C’ means that our product is a Compatible version of the Original Equipment Manufacturer (OEM) part number.

    For example

    Cisco® Part Number: SFP-10G-SR

    ATGBICS® Part Number: SFP-10G-SR-C

    This method of part numbering gives our clients the assurance that they will be supplied the fully tested, 100% compatible, MSA Compliant version of the OEM part.

    What does MSA Compliant mean?

    Multi-Source Agreement (MSA) is a multi-vendor specification that defines the form factors and interfaces of an optical transceiver. Manufacturers adhere to MSAs to ensure interoperability and interchangeability between interface modules. This enables compatible manufacturers such as ATGBICS to provide compatible solutions to the same specification as the OEM.

    With the assurance of quality, reliability and compatibility, our clients are reaping the benefits of buying compatible alternatives to OEM with significant cost savingsshorter lead times and exemplary customer service.

    In short you can be sure that all our products are:

    • 100% Compatible
    • Fully Tested
    • Backed By A Lifetime Warranty
    • Conform To ALL Industry Standards & Protocols
    • Each Product Uniquely Serialised And Traceable
    • Up to 90% cheaper than the OEM alternative but equal in performance & reliability
    • With lead times of days not weeks or months
    • Easy to ensure compatibility. Our SKUs are equivalent to the OEM SKU suffixed with ‘-C’ to denote ‘compatible’
