Fiber Optic Splitter Model and Specification Table

Fiber optic splitters are available in various models including bare fiber, cassette, tray, and rack-mounted types, with specifications such as split ratio, insertion loss, wavelength range, and connector options.Fiber Optic Splitter Specification TableModel / TypeInput / OutputSplit RatioInsertion LossPDLWavelength RangeConnector TypePackaging / MountingNotesBare Fiber PLC Splitter1xN or 2xN1:2, 1:4, 1:8, 1:16, 1:32, 1:64≤3.8 dB≤0.2 dB1260–1650 nmNone (bare fiber)Compact housing for splice trays, wall-mounted boxes, ODFHigh-density networks, customizable split ratios, Telcordia GR-1209/GR-1221 compliant, CE/RoHS certified Cassette Splitter1xN1:2 to 1:323.5–4.0 dB typical≤0.2 dB1260–1650 nmSC/LC/FC (customizable)Pigtail cassetteComplete protection for inner optical components, easy installation, commonly used in PON networks Tray Splitter1xN1:2 to 1:323.5–4.0 dB typical≤0.2 dB1260–1650 nmSC/LC/FC (customizable)19” standard ODF or cabinetSupports pigtail or adapter type, ensures fiber curvature radius, allows channel capacity increase Rack Panel Splitter1xN or 2xN1:8 to 1:32≤4.0 dB≤0.2 dB1260–1650 nmSC/LC/FC (UPC or APC)19” rack mount, 1UModular design, suitable for POL, PON, FTTX, CATV, DWDM/CWDM systems, GR-1209/GR-1221 qualified, GR-326 certified connectors FBT Splitter (Fiber Bundle Technology)1xN1:2, 1:4, 1:83.5–4.5 dB≤0.3 dB1310–1550 nmSC/LC/FCBare or connectorizedTraditional splitting method, lower uniformity than PLC, cost-effective for small split ratios Key Notes on Fiber SplittersSplit Ratios: Most commonly powers-of-2 (1x2, 1x4, 1x8, etc.), but odd ratios (1x3, 1x5) are also used in some network designs .Insertion Loss: Increases with higher split ratios; typically, each doubling of outputs reduces power by ~3 dB .Connector Options: SC, LC, and FC connectors are standard; UPC or APC polishing is selectable depending on network requirements .Applications: Suitable for PON, FTTX, POL, CATV, DWDM, and CWDM networks. Bare fiber splitters are ideal for high-density or custom installations, while cassette, tray, and rack-mounted splitters provide protection and ease of deployment .Standards Compliance: Most splitters comply with Telcordia GR-1209/GR-1221, GR-326, and RoHS/CE standards . This table provides a comprehensive overview of fiber optic splitter models and specifications, enabling network designers and engineers to select the appropriate splitter type for their optical distribution needs.
