Telco Block

Telco Blocks are utilized to connect phone systems to data networks. There are two popular forms of Telco Blocks: the 66 Block and the 110 Block. The 66 Block is quite common in modern phone systems, as they simplify connecting multiple phone lines. The 66 Block is also referred to as B-Blocks, M-Blocks, and as split-50 Blocks. In addition, the more recent 110 Block is becoming ever more popular. The 110 Block preserves the twists in each twisted pair of cable right up to the connection point. These Telco Blocks are commonly used for data networking applications, and have superior crosstalk characteristics over the 66 Block. The 110 Block also allows for higher density terminations and provides for higher bandwidth specifications.

The 66 Block with Snap on Cover is a 50 pair Telco Wiring Block composed of durable fire retardant material. This 66 Block is suitable for terminating high performance unshielded twisted pair cable. Its performance exceeds CAT5E requirements specified in TIA/EIA 568-B.2. In addition, this 66 Block mounts on a 89B bracket.

Our Connecting Block, 110 Type accommodates 20 to 26 AWG diameter conductors. This 110 Block is designed for repeated use on 110 Data Wiring Blocks and is color coded for easy installation; this Telco Block is designed for voice and data applications, and color coded for organized and simplified use.
