Ever astonishment meet what the heck was an “OC48″? Not astonishingly some meshwork engineers and IT managers aren’t up to pace (no paronomasia intended) on meet what OC rattling means…and what every is acquirable to enahnce their company’s applications within this bandwidth category.

So….here’s a hurried separate downbound to ordered you straight.

The OC (optical carrier…fiber receptor supported band meshwork )hierarchy goes as follows, play with a T3/DS3 electrical traveler and then on to an OC-1:

DS3 (Electrical) = 44.736mbits/sec = 28 T1s/DS1s

STS1 (Electrical) = (1) DS3 @ 44.736mbits/sec with SONET (Synchronous Optical NET) disbursement = 51.840mbits/sec

OC-1 (Optical) = (1) STS1 on Optical facilities

OC-3 = (3) OC-1s = 155.52mbits/sec

OC-9 = (9) OC-1s (not commonly used) = 466.56mbits/sec

OC-12 = (12) OC-1s or (4) OC-3s = 622.08mbits/sec

OC-18 = (18) OC-1s (not commonly used) = 933.12mbits/sec

OC-24 = (24) OC-1s (not commonly used) = 1.244gbits/sec

OC-36 = (36) OC-1s (not commonly used) = 1.866gbits/sec

OC-48 = (48) OC-1s or (4) OC-12s or (16) OC-3s = 2.488gbits/sec

OC-192= (192) OC-1s or (4) OC-48s or (16) OC-12s or (64) OC-3s = 9.953gbits/sec

The think for the stair-stepping of the OC Hierarchy is cod to the fact that the incoming acquirable take of multiplexing (’muxing”) of lower-level circuits is commonly 4: (4) OC-3s = (1) OC-12, and (4) OC-48s = (1) OC-192.

This muxing plot is commonly settled by the equipment manufacturers and is pretty such an adoptive accepted in the Telecom playing - thus the demand of the lesser-common bandwidth aggregations same OC-9, OC-18, etc. The exclusive omission is the OC-3, which was necessary to earmark the upper-level organisation to work.

Hope this delicacy of content helps the meshwork organisation decisions for your playing now….and in the future!
