Cisco (CSCO) is prepping a successor to its costly/high-margin CRS-3 core router that will be called the CTR and offer up to 1Tb/s of capacity per slot, according to a document ontained by Light Reading. That figure represents a solid increase from the CRS-3's 400Gb/s per slot, and is also above the 800Gb/s delivered by Alcatel-Lucent's (ALU) 7950 core router, launched last year to much fanfare and PR mudslinging. Juniper's (JNPR) T4000 is at 240Gb/s per slot. The CTR is also said to support Cisco's CPAK silicon photonics modules, which some analysts (though not all) view as a threat to JDS Uniphase (JDSU) and Finisar (FNSR).
