It is commonly used when the received optical power is too strong for the optical receiver, or when engineers need to balance link budgets during installation, testing, and maintenance.<\/p>\n<p>This SC UPC Attenuator is suitable for FTTH, FTTX, CATV, telecom rooms, ODF systems, PON networks, fiber testing, optical transceivers, media converters, switches, routers, servers, storage devices, and optical network maintenance.<\/p>\n<p>The SC\/UPC connector uses an angled polish structure, making it suitable for low-reflection single mode optical systems. Compared with UPC connectors, UPC connectors are more commonly used in FTTH, CATV, PON, and optical distribution environments where return loss performance is important.<\/p>\n<p>Luleey\ub294
