MTP/MPO Fiber Loopback Cable

Name: MTP MPO Fiber Loopback | MTP/MPO Loopback | ETL Malaysia
SKU: ETL-MPO-LB001
Availability: InStock

The MTP/MPO Fiber Loopback provides an optical loop path within an MTP/MPO connector, allowing optical signals to be routed from the transmit side back to the receive side.

It is designed for testing the transmit and receive capabilities of network equipment, particularly in telecommunications and data communication applications.

The compact, high-density design supports multiple MTP/MPO configurations and can be supplied with or without attenuation. Available configurations include 8-core QSFP, 12-core, 16-core and 24-core options, with both single-mode and multimode fiber configurations supported by the product specification.
