As examples: The Cisco GigaStack GBIC - https://www.mtmnet.com/PDF_FILES/WS-X3500-XL_DataSheet.pdf - uses the 6 pin IEEE1394 (Firewire) connector 1000Base-CX uses twinax shielded twisted pair and the "HSSDC" connector - e.g: https://www.ebay.com/itm/372539150316 I've seen (but cannot find a photo at the moment) a DB-9 GBIC (to allow connection to DB-9 fiber channel stuff) Someone used to sell an HD-BNC GBIC - basically the GBIC version of https://www.bhphotovideo.com/c/product/1430372-REG/wohler_sfp_sdi_output_3g_sdi_transceiver_hd_bnc_connectors.html I've also somewhere seen an "F-style" coax GBIC to allow reuse of in-building coax - basically looked like a GBIC form factor version of http://www.mdslink.com/magic-sfp/ W > Sent from my iPhone > > On Nov 15, 2022, at 8:49 AM, Bjørn Mork <[email protected]> wrote: > > Maybe you're thinking of X2, looking similar to GBIC but even bigger? > There were converters taking 2 gig SFPs in one X2 slot. > > Don't think either GBIC to SFP or GBIC with LC makes much sense.
