BN24B-XX = FDDI MIC-to-FDDI MIC Patch Cable
BN24D-XX = FDDI MIC-to-2.5mm Bayonet ST-type Connector Patch Cables
BN24E-XX = Dual 2.5mm Bayonet ST-type Connector Patch Cables

manual - order no. EK-DECSY-FP.
note: Need to stay within the maximum allowable loss for OPEN DECconnect
System; splices = .4dB and connectors = .7dB. The maximum allowable
system loss for an FDDI network is 11 dB with the recommended
62.5/125 micron multimode fiber type.
The actual cable length required needs must be determined during the
fiber optic cable plant design phase.
Approved fiber optic cable manufacturers for use in the OPEN
DECconnect System Fiber Optic structured wiring are, AT&T, Siecor,
Belden/Cooper Industries, Mohawk, and Chromatic Technologies.

| 194.1 | New FDDI fiber cables? | STAR::STOCKDALE | Wed Jan 05 1994 18:40 | 9 | |
Does anyone know what the cable designation is used on 'new' DEFAA modules? I don't know if it is new or not but some new adapters that we got had some strange connectors on them and now we need to find out what kind of cable to get to connect to them. Thanks. Dick | |||||

DEFAA is the DEC FDDIcontroller/FUTUREBUS+ adapter. I believe it uses
ANSI MIC connectors, but I'm not positive. Can anyone verify?

| 194.4 | Do you have Single Mode variant of DEFAA? | SCHOOL::PAQUETTE | Thu Jan 06 1994 11:11 | 14 | |
Hi, The DEC FDDIcontroller/FUTUREBUS+ module, DEFAA, is equipped with modular PMD (MODPMD) FDDI interfaces, which can be changed to allow the module to connect to either multimode fiber via the standard ANSI MIC connector, or to single mode fiber (SMF) via an FC connector. In fact in the Dual Attached (DAS) variant, you could have one of each. Dick, I'd guess that you have the SMF variant. You can check with the Product Manager, George Nielsen (DELNI::G_NIELSEN) to determine the actual variation you have. Note that you will need a SMF card in your concentrator, (or whatever you are connected to) to make this work. Also there is a minimum attenuation required of your cable plant when using SMF. Please contact Dick Kirk (LEVERS::KIRK) if you have more questions on the SMF. Mike | |||||
