MTP Loopback

ZGT MTP Loopback is designed for testing and troubleshooting high-density fiber optic networks. It creates a loop between transmit and receive channels, allowing network equipment to check optical signal transmission and reception. This makes it useful for testing optical transceivers, switches, and other fiber optic communication devices. Available in standard and low-loss versions, the MTP loopback supports different testing requirements. With an operating temperature range of -40°C to +75°C, it is suitable for data centers, telecom equipment testing, and optical network maintenance.
