Seemingly excessive failures on OPTera 3500

We have been seeing circuit pack and intercard failures on OC48 transceivers on a lot of our OPTera 3500 network elements, which end up being cleared by having the faulty card replaced (almost always an OC48 transceiver, PEC# NTN440BB or similar w/different wavelength). Most of these were just turned up recently in many different areas of the nation, which means they're not being turned up by the same people (hopefully eliminating the theory of installation point of failure), in many different environments. Has anyone else noticed a trend with these?

Your post is so old that probably you won't see the answer to this inquiry. And unfortunately you didn't leave a pointer to e-mail.

We have also seen a high failure rate on the OC-48 modules, and after a lot of testing we discovered the reason for it and it's easily corrected by ensuring proper airflow through the system. If you are still around contact me for details at westes AT earthbroadcast.com.
