Product Introduction
The FRM series is a high-density channel product that can be configured with single-mode, multi-mode, or single-multi-mode hybrid fibers. Products with resistance to environmental factors such as shock, vibration, high and low temperatures are available. The product line includes two extended models, FRMA and FRMB.
FRMA features a tail fiber outlet and often used for 8 or more channels, with up to 60 channels available.
FRMB features a flange port, without tail fiber output, and can be configured with 2 to 4 channels.
