This non-jacketed, 24 AWG cross connect wire is very flexible and cost effective for your telecom installation. The Cross Connect Wire we provide to accommodate your application, is voice grade twisted pair cable provided on spools in 1,000ft increments. 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. Our Connecting Block, 110 Type accommodates 20 to 26 AWG diameter conductors. In addition, this 66 Block mounts on a 89B bracket. Its performance exceeds CAT5E requirements specified in TIA/EIA 568-B.2. This 66 Block is suitable for terminating high performance unshielded twisted pair cable. The 66 Block with Snap on Cover is a 50 pair Telco Wiring Block composed of durable fire retardant material. The 110 Block also allows for higher density terminations and provides for higher bandwidth specifications.

These Telco Blocks are commonly used for data networking applications, and have superior crosstalk characteristics over the 66 Block. The 110 Block preserves the twists in each twisted pair of cable right up to the connection point. The designation 110 is also used to describe a type of insulation displacement contact (IDC) connector used to terminate twisted pair cables, which uses a punch-down tool similar to the older 66 block. Connecting blocks are required for punching down 110 blocks.

110 blocks have less cross-talk vs 66 blocks and can provide increased number of terminations.

In addition, the more recent 110 Block is becoming ever more popular. A 110 block is a type of punch block used to terminate runs of on-premises wiring in a structured cabling system. 110 connecting blocks are used for connecting telecommunication and data communication in structured wiring. The 66 Block is also referred to as B-Blocks, M-Blocks, and as split-50 Blocks. The 66 Block is quite common in modern phone systems, as they simplify connecting multiple phone lines. There are two popular forms of Telco Blocks: the 66 Block and the 110 Block. Telco Blocks are utilized to connect phone systems to data networks.
