EFB Fiber-Pigtail ST 50/125µm OM4, set 12 colori, 2m

With a modal bandwidth of 4700 MHz·km at 850 nm, this 12-fibre pigtail set is built for high-speed multimode backbone links. Each 2-metre pigtail is terminated with an ST connector and colour-coded according to DIN VDE 0888 / TIA-598-C, making installation and identification straightforward in patch panels and splice closures.

Overview

The EFB O3307.2 is a set of twelve 50/125 µm OM4 multimode fibre pigtails, each 2 metres long and pre-terminated with an ST connector. The pigtails feature a 0.9 mm buffer and LSZH jacket, ensuring low smoke and zero halogen emissions in case of fire. With insertion loss ≤ 0.3 dB and return loss ≥ 30 dB, they deliver reliable performance for 10G, 40G, and 100G Ethernet applications up to 550 metres at 850 nm.
