the next generation telco central office ds3 coaxial connector !"# s eries m iniature bnc (m $ bnc) the mini-bnc 250 rf connector series from trompeter was designed specifically for ds3 telco coaxial central office applications to allow higher interconnect density while preserving the positive characteristics of the trompeter full size bnc. in fact, the 250 series provides for higher density of interconnects in a given area. alternative products such as the smb, while sometimes offered in true 75 ohm, do not have bayonet locking features. some have no interface locking feature at all and some use ?osilock?technology, which is quite expensive and not nearly so well known in the telco space as the bayonet locking system. also, smb connectors were not typically designed to be field-terminated while the bnc was and this smaller version 250 series, the mini-bnc is. in researching this next-generation rf connector series, trompeter canvassed many of the mainstream service providers and visited several central office facilities to determine clear goals for this new connector. the design objective became very clearly one of maintaining all the characteristic of the trompeter bnc while allowing higher density. at trompeter, we rank the importance of trained and well-equipped installers at least equal in value to the connec- tor itself with the mini-bnc there is no need for retraining field installers and no need for new tooling for those installers. the elements of the trompeter design that were specifically targeted for inclusion are: 1. same crimp/crimp design ?the trompeter bnc and the trompeter miniature bnc are field terminated with the exact same cable strip tools, contact crimp tools, and crimp sleeve crimp tools. the effectiveness of a crimp/crimp connector has been proven over 30 years of use in the telco ds3 application involving an estimated 50 million connectors. 2. same installation tooling ?the trompeter tooling for the telco ds3 cable termination assignment is truly best-in-class and is widely used by the wide base of trained telco installers. with field tooling already deployed and installers already trained, the use of the upl250-xxx will be easily implemented. the tools are the same, the strip dimensions are the same and the installation is the same. 3. same footprint on the jack side ?since many high density applications such as routers use smb or smz jacks to achieve interconnect density, the 250 series jacks have been carefully designed to use the same footprint on the printed circuit board, allowing easy implementation of this innovative technology. 4. 75 ohm ?the ds3 line in the telco central office is 75 ohm and the mini-bnc is as well. further, this characteristic is tightly designed and manufactured to stay at this impedance over the frequencies of interest and beyond. this allows rf ?ead room?and presents a matched impedance condition to the electromagnetic field that is so important to return loss performance. upl250 series 5. bayonet locking coupling mechanism ?the primary advantage of the bnc over threaded alternatives is a quick-connect feature enabled by the pair of lugs on the jack side interface and the j-slots on the plug side interface. this mechanism is positive and can be sensed to be fully mated when engaged. in the case of the trompeter product, the bayonet is held in a positive force condition under load for the life of the part (typically 30 or 40 years) by a beryllium copper wave washer that does not deform over time (lower cost connector products now available on the market may use alternative materials in lieu of beryllium copper for this function.) 6. visual inspection ?because the mated condition is so important to flawless signal processing over long periods of time, the bayonet coupling can be visually inspected to determine if the plug is fully engaged to the jack. this is unique to the bnc and mini-bnc product since threaded parts do not have a positive stop representing full engagement. the trompeter design facilitates this inspection process by a mark on the plug coupling sleeve that can be aligned and shown to be fully engaged. trompeter electronics ? direct: 1-818-707-2020 ? toll free: 1-800-982-2629 ? fax: 1-818-706-1040 ? website: www.trompeter .com
