GBIC Modules

Is anyone aware of any other companies that make GBIC modules. Are these recognized by Cisco? I know that Cisco GBIC's are around $500.00. All suggestions are appreciated.

Re: GBIC Modules

There are lots of other companies making GBICs, but only Cisco GBICs are supported by Cisco.

For some of the more recent GBICs (1000base-T / CWDM), only Cisco GBICs will actually work, and the same holds true for SFPs.

Re: GBIC Modules

"WDM, copper, and SFP GBIC's all include a GBIC EEPROM "code" that certifies the GBIC as coming from Cisco. New versions of IOS/CatOS check this code to verify the GBIC - if the code is not found, or is not valid, the software will disable the port in software and will not allow traffic to pass. Older GBIC's (5484/5486/5487) were manufactured before this feature was introduced, and do not contain this feature. Regardless, TAC will not troubleshoot a GBIC that was not purchased from Cisco, the same policy as Flash/DRAM memory."
