110 Series SMPTE 304M Connectors

Physical Contact Connectors – Hybrid Connectors

Amphenol Fiber Systems International (AFSI) manufactures 110 series connectors conforming to the SMPTE 304M Standard. These hybrid connectors are designed for high definition broadcast television cameras used worldwide for the production and transmission of high definition TV programming.

The 110 series connectors feature two fiber optic termini and four electrical contacts. The high precision fiber termini provide superior single mode performance, while the two auxiliary electrical contacts permit supply of power remotely to the camera at long distances from the studio, control van or CCU. Two additional low voltage electrical contacts are provided for communication purposes. The connectors are designed for use in conjunction with SMPTE 311M Standard cables.

The connectors are fabricated from stainless steel to withstand corrosive elements when exposed to the extreme harsh outdoor environments and are sealed to an IP68 rating to block out ingress of damaging dirt, dust and moisture. The robust shells are also designed with thick walls to prevent damage from rough handling during outdoor deployment at venues such as professional sports arenas. Metal or rubber dust caps are available to protect against contamination of the interfaces. The connectors are designed for easy termination in the field.
