Description
The TW (4 in 1 Universal SC/APC) waterproof assembly provides the most cost-effective method of deploying optical fiber in outside-plant distribution networks at speeds significantly faster than traditional field installations. It guarantees an easy, one-step connection through a combined push-pull insertion and nut-style mechanical latch, and mates with Slim, ZTE, Optitap and Fastconnect adapters. Cable can be armored or non-armored.
Applications include connection to Remote Radio Units (RRU/RRH), FTTA, FTTH equipment and other outdoor systems. The unique housing design allows it to be supplied on a factory-terminated and tested cable assembly, or retrofitted to existing outdoor cable assemblies.
