FIBER MANAGEMENT ASSEMBLIES AND TRAYS AND NETWORK INTERFACE DEVICES INCORPORATING SUCH ASSEMBLIES AND TRAYS

Fiber management assemblies, trays and network interface devices for use in telecommunications that incorporate such assemblies and trays are described. Fiber management trays can include integrated slack storage systems and mechanical fiber splice devices mounted into integrated splice holding grooves, where the mechanical fiber splice devices are actuated by a fiber splice actuation mechanism positioned over the mechanical fiber splice device, as are network interface devices incorporating such assemblies and trays.
