We present a releasable multifiber connectivity solution for parallel optical links, which is realized by combining fiber arrays, microlens arrays, and V-grooves. Vision and active alignment are used to assemble the different parts. A low-cost adhesive bonding technology was developed for attaching the microlens arrays to the substrates. Optical coupling losses (per lens transition) of well below 1 dB for multi-mode fibers, and below 0.5 dB for single mode fibers over 12 channels for 850 nm, 1300 nm and 1550 nm wavelength were achieved. First reliability tests confirmed mechanically stable adhesive bonds under temperature cycling and damp-heat stress conditions, as well as optical loss variations below 0.2 dB for temperature cycling between -40degC and 50degC. In addition, a first realization of a releasable 90deg connection between fiber arrays based on V-groove alignment is presented
