OSU Optical Splitter Unit

Product Overview

OSU optical splitter unit is a splitter based on planar optical waveguide technology introduced by Visint. It is mainly used for communication trunk, MAN, LAN, private network, DPI, FTTX of PON, etc. Our 1*N, 2*N planar waveguide optical splitters are small and cost effective. They support a wide wavelength range (1260-1620nm) and can provide customers with low insertion loss and low polarization dependent loss.

Visint® Vispace 1000 series optical multiplexing and demultiplexing equipment is widely used to solve the problem of insufficient optical cable resources in transmission. Fabricated by thin film filter (TFF) technology and planar lightwave circuit (PLC) technology, multiple optical carrier signals are multiplexed onto a single-core optical fiber for transparent transmission, supporting dual-fiber bidirectional, single-fiber bidirectional, single-fiber single unidirectional and other types.


Application 1: Dual-fiber Bidirectional

The dual-fiber bidirectional multiplexes multiple optical carrier signals onto the two-core optical fiber for transmission, thereby realizing the use of the two-core optical fiber to transmit multiple services, thus greatly reducing the investment cost and saving the cable laying time.

Application 2: Single-fiber Bidirectional

The single-fiber unidirectional uses the optical reversible characteristic to multiplex multiple optical carrier signals onto a single-core optical fiber for transmission, thereby realizing multi-channel transmission by using one-core optical fiber, thus greatly reducing investment cost and saving cable laying time.

Application 3: Smooth Upgrade

The smooth upgrade is to access the splitter through the expansion port of the splitter in the original WDM system to achieve smooth upgrade and expansion without affecting the original service.
