http://www.finisar.com/product/product.php?product_id=165&product_category_id=150 CWDM GBIC OC48 Transceiver with APD Receiver (FTR-1621) Seems nifty. Anyone using this? Also, me making my once-a-year request; anyone know of GBICs based on ITU-Grid frequencies that would work with Cisco 15216, for example?
