Full Bonded NID Splitter with Test Jack and EMI Suppression


The Comtest NID-TJ-FB-EMI POTS Splitter is two complete VDSL2 splitters in a single footprint. Keeping with Comtest’s reputation for innovative designs, the NID-TJ-FB splitter will simplify your installation and provide filtering on both lines, while only occupying one slot in the NID/SNI. The NID‐01V-FB-EMI is designed for simple and easy clip‐in installation in virtually all industry standard NIDs, allowing for the continued use of existing infrastructure while upgrading to new bonded VDSL2 standards.

The Comtest NID-TJ-FB-EMI has the added benefit of a built in Common Mode EMI Filter. The Common Mode EMI Filter provides insertion loss of 30dB of couple signals (Electromagnetic interference signals) without adversely affecting the DSL signal (differential mode). This helps to reduce the effect of EMI on DSL signals.

The NID-TJ-FB includes secondary surge protection on both lines. The Splitter is environmentally sealed against the elements. This, in cooperation with the gel filled IDCs, protects against the risk of corrosion or failure caused by nicked wires during stripping.
