DESIGN RATIONALE: The OTDR cable box is designed to aid in the use of the OTDR when testing fiber optic cables. The OTDR transmission cable box is used with an optical time domain reflectometer (OTDR) to help minimize the effect of the OTDR transmission pulse on measurement uncertainty.

GREAT SEALING: There is no seam in the middle of the fiber, and the excellent sealing is waterproof and explosion-proof.

SPECIFICATIONS: With single-mode fiber type for distances up to 2000 meters, and the test cable is long enough to greatly reduce usage restrictions.

EASY OPERATION: The optical fiber transmission operation loss is low, and the optical fiber box is small in size and light in weight, which is easy to operate and transport.

EXCELLENT MATERIAL: This extension cord is made of excellent fiber and plastic material, with good toughness and abrasion resistance for a long service life.
