The programming for each optical transceiver is unique. Many of the OEM’s structure their EEProm data
and even discrete hardware attributes in order to deter customers from buying
anything but their own. Some of these
nuances in the optical transceiver can include: check digit and algorithm
verification required by the OEM’s IOS. Other factors include the guarantee of
non-repeating serial numbers and the assurance of embedded CLIE and MCU attributes. Approved has invested heavily in Research and
Development to ‘break’ the monopolistic activity by the OEM’s. and offer a
quality solution to our clients. To read more about how the Switch OEM’s create
technical barriers that push the limits of US Law read Cisco's Secret Franchise.
Approved Optics shares a relationship with the same contract
manufacturers that build for of the major OEM’s and we have people on the
ground assuring that they are building with the same discrete components. After
confirming the exact same discrete hardware components have been included
during the manufacturing of the optical transceiver, the 3rd party
provider then needs to address EEProm and Algorithm ‘tricks’ that the OEM has
put in place to keep customers from circumventing their brand with quality
optics. Approved has invested hundreds of thousands of dollars in
multi-platform switch router technology and software, platform specific EEProm readers/editors,
and special test software that is unique to Approved Optics. The check digit
hardware programming is performed on the transceiver to assure hardware threshold
functionality. Approved then verify’s the proper algorithm, in a 3rd
party format for the transceiver, to insure that the IOS will verify and
approve the functionality in the port without an error message and with full
feature functionality. EEProm attributes are unique to every OEM transceiver - Approved
has been able to uniquely parallel the attributes of the OEM without
threatening intellectual property laws, so that the optical
transceiver will function exactly like an original in the machine and IOS
intended. Approved applies a specific serial number sequence code to the NVRAM
so that the serial number on that specific transceiver will never replicate in
the network. This is very important because the IOS of many OEM’s will check
for duplicates and shut down the port.
Upon completed programming, our test engineers verify this
process with our unique in-house Q/A software and a follow up environmental
test in the actual switch.
