In today's fast-paced digital landscape, the demand for high bandwidth, extended reach, and efficient edge access continues to surge. To cater to the evolving needs of big campuses and newly built networks, a cost-effective fiber solution is crucial to ensure future-proofing. Our passive optical fiber solution emerges as the perfect answer, enabling the transmission of multiple services through a single fiber. This revolutionary approach significantly reduces fiber cabling, construction, and operational costs. Our OTN infrastructure boasts unparalleled flexibility, facilitating seamless fiber expansion. Deploying color light transceivers and passive networking equipment, a single port can now be multiplexed into multiple channels. This enables the support of various service applications, including Ethernet, SDH/SONET, fiber channel, FTTx, and CATV.
