114-32050C. Protective Cover (Figure 4) The protective cover is made of anti-static material. The cover is common for both the plug (module) and receptacle (backplane) connectors. The cover plugfits within the receptacle connector shell; alternatively, the cap fits over the plug housing. The cover serves to protect the polished end faces of the MT ferrules. As these are not sealedconnectors, the cover is not expected to seal-out dust particles form the optical interface.Figure 43.6. Special Assembly ConsiderationsA. System DesignThe system into which the VITA 66.1 connectors are installed must support the weight of the drawer whenmodules are engaged (for example, the drawer must bottom on a built-in stop, not on the connectors).B. Optical Loss BudgetAn optical loss budget analysis is recommended to make certain the system will work over the proposedlink. Parameters such as environmental exposure and end face maintenance techniques can addvariance to loss budget inputs. For the loss through the module to backplane connection interface, thebudget is typically 1.2 dB at 850 nm and 1300 nm. The return loss budget should typically be better than20 dB. More detail on optical performance is provided in Product Specification108-2467.C. Guide Hardware (Figure 5)The interaction of the guide pin and guide module provide error-free mating and prevents damage to theconnectors. Guide hardware is recommended for multi-connector, large and heavy daughter cardapplications, and conditions where misalignment tolerances given in Section 3.7 cannot be met. Universaland keyed guide hardware are available for proper mating and allow up to 3 mm offset for blind mating.The guide hardware consist of a guide pin and guide module. The connectors require 2 guide pins (for thereceptacle) and 2 guide modules (for the plug), which must be attached to the respective PWB.

Mating ForceA retained mating force between the module and backplane MT ferrules is necessary for reliable opticalperformance during operational conditions. A spring within the plug (module) connector generates thismating force. The mating force varies as the module and backplane connectors mate through a moduleinsertion range.The optical interconnect requires a minimum mated force of 7.8 N [1.75 lb] for each MT ferrule. Themaximum mated force required at maximum connector engagement is 11.8 N [2.65 lb] per MT ferrule.C. Connector Alignment (Figure 16)Proper alignment is essential to ensure full engagement of the mating connectors and to ensure the MTferrules are not damaged during mating. Due to the manufacturing tolerances typical of VITA 46 plug-inmodules and backplanes, the VITA 66.1 connector system incorporates float to enable aligning the matinginterfaces of the MT ferrules.The lateral clearance existing between the shell and insert housing of the backplane connector provides aminimum of 0.25 mm [.010 in] float in both the x- and y- directions. The backplane connector guide pinsand plug cavities accommodate a maximum misalignment of 1.02 mm [.040 in] in. The exterior systemdesign shall ensure the connectors are located relative to each other within that range. Also, the systemshall axially align the connectors within a 2 angle.Rev B13 of 17
