LightVISION VM industrial optical module with LightSNAP interface
The LightVISION™ VM is a screw-in, robust industrial and RoHS optical module with LightSNAP™ interface.
LightSNAP interface adds a standard MPO pluggable optical interface to the LightVISION VM optical module. This combination allows a standard MPO cable to be plugged into the optical module and also mounted on the face-plate of a box or line-card. This approach offers a standard MPO cable connection with a robust, board mounted optical engine providing small size (footprint) and convenient optical cabling at the same time. In addition, the MPO connector is covered with an outside cover boot addressing the issue of water and dust contamination.
