Multicore Fiber Coupler FSCS4-1550LC
Multicore fiber couplers distribute or combine optical power among fibers and support multiplexing of multiple modes in multicore fibers. Directional coupling evenly distributes inputs among output branches with low coupling loss, greatly simplifying multicore coupling. Fan-in/fan-out applications include space-division-multiplexed communications, optical couplers, and network equipment. Operating wavelength: 1550 nm. Products include 4-core and 7-core couplers with LC/UPC interfaces, single-mode and few-mode transmission, low loss and crosstalk, and high mode extinction ratios. 4-core couplers. Models: FSCS4-1550LC, FSCL4-1550LC. Compact 4-core package. Interface: LC. Single-mode/few-mode transmission. Wavelength: 1550 nm. A 4-core coupler converts 1 input into 4 outputs, with single-mode or few-mode transmission at 1550 nm through LC interfaces in a compact package. For 4-core couplers at 1550 nm, fundamental-mode insertion loss is <1 dB and typical intercore crosstalk is -45 dB. Few-mode transmission (LP01, LP11a, LP11b) has insertion loss <2.5 dB, mode crosstalk <18 dB, and typical intercore crosstalk -34 dB. Features include low loss/crosstalk and high mode extinction. 7-core couplers. Models: FSCS7-1550UPC, FSCL7-1550UPC. Compact 7-core package. Interface: UPC. Single-mode/few-mode transmission. Wavelength: 1550 nm. A 7-core coupler converts 1 input into 7 outputs with single-mode or few-mode transmission at 1550 nm through UPC interfaces in a compact package. For 7-core couplers at 1550 nm, fundamental-mode insertion loss is <1.5 dB and typical intercore crosstalk is -42 dB. Few-mode transmission (LP01, LP11a, LP11b) has insertion loss <3 dB, mode crosstalk <15 dB, and typical intercore crosstalk -30 dB. Features include low loss/crosstalk and high mode extinction.

Single-mode dual-wideband tree/star coupler / 1x4 - Operating wavelength: 1310/1550±40 (*1310/1550±20) or Customized Single-mode dual-wideband tree/star coupler / 1x4 - Maximum insertion loss: 7.3 (*7.2) Single-mode dual-wideband tree/star coupler / 1x4 - Uniformity: 1.6 (*1.4)
Fused biconical tapering brings two or more stripped fibers together in a defined arrangement, fuses them under high heat and simultaneously stretches them from both sides to form a special double-taper waveguide in the heated region for optical power coupling. A splitter/coupler distributes one optical input to multiple or two outputs, or combines multiple or two inputs into one output. Port configurations include X, Y, star and tree couplers.
