40G/100G LR4 ER4 ZR4 Transceiver Dual fiber to Single fiber Converter/Circulator


40G/100G LR4 ER4 ZR4 Transceiver Dual fiber to Single fiber Converter/Circulator (1310nm & 1550nm Options)

In the 40G / 100G data transmission networks, it may require dual fiber to singe fiber conversion. This 100% passive Dual-fiber to Single-fiber converter/circulator for bidirectional transmission of 40G/100G LR4/ER4/ZR4 transceivers over one fiber, enabling multiple 40G / 100G services using the existing optical fibers and best suitable for bi-directional signal transmission over one fiber by operating range: 1310nm or 1550nm.

This converter/circulator works in O-band (II transmission window) or C-band (III transmission window). They operate based on the orthogonal polarization of bi-directional light, which makes it possible to transmit in two directions over the same wavelength.
