OFT-850 SMPTE Hybrid Cable Test Set

OFT-850 SMPTE Hybrid Cable Test Set

The OFT-850 set consists of SMPTE SOURCE and SMPTE TESTER unit. The hybrid cable tester is designed for testing of loss in optical fibers and checking of continuity of copper pairs in hybrid cables. It combines optical light source on one side, optical power meter on other side and copper wires checker. It is ideal for testing large spaces of LEMO SMPTE Hybrid System for Broadcast Infrastrucutre Networks. The ruggedized aluminium case makes the unit ideal for field operation. The memory capacity allows storage and uploading of more than 1000 measurements including cable number, result of metalic wires check and optical power value or insertion loss. The tester supports memory download and test report generating. The Lithium rechargeable battery ensures long term working with minimal operation costs.
