Configuration Options

• Breakout leg diameter — 2.0 mm standard, sturdier and easier to handle for direct patching and longer legs; 0.9 / 1.6 mm on request for tighter, higher-density routing inside trays and panels.
• Leg arrangement — equal-length for same-side terminations and standard patch fields; stepped (staggered) where connectors land at different port rows or across floors, so each leg reaches its port with no excess slack.
• Leg numbering & labeling — legs are bundled and numbered to your port schedule; color-coded boots and custom labels / tags on request.
• Ends — connectors at both ends as standard; one end unterminated (bare fan-out for in-box splicing) can be quoted on request.
• Overall and breakout lengths are built to your drawing; pulling eye, furcation tubing and reel packaging on request.

Typical Applications

• Data-center multi-fiber trunking and cabinet cross-connection where individual LC / SC ports are preferred over an MPO cassette.
• Building indoor structured cabling and riser / vertical floor distribution.
• ODN distribution-box convergence and branch wiring to termination panels.
• Enterprise networks, low-voltage (ELV) systems and large integrated cabling projects.
• Boundary: for a QSFP parallel-port breakout (MPO one end, LC the other) use XHT-D02; for armored or outdoor routing see XHT-D04.

Quality You Can Verify

• Factory-terminated under controlled epoxy, cure and polish process — consistent end-face finish versus field splicing.
• Every connector insertion- and return-loss tested; end faces inspected for cleanliness and defects per IEC 61300-3-35, then cleaned and sealed with dust caps.
• Legs are numbered and the fan-out matches your port schedule; a per-assembly test record is available on request.
• Standard, non-OEM connectors interoperate with standard adapters and panels.

FAQ

Q1. Mini breakout (D03) or MPO fan-out harness (D02)? D03 has no MPO — both ends are individual LC / SC / ST / FC connectors for indoor trunk, riser and ODN termination without a cassette. D02 has an MPO at one end for a QSFP parallel-port breakout.

Q2. Single-mode or multimode? This breakout is built mainly in single-mode: G.652.D and G.657.A1 are standard, G.657.A2 / B3 on request. Multimode OM1–OM5 is available on request for legacy or LC-based indoor trunks; for high-density multimode data-center links the MPO trunks / harnesses (XHT-D01 / D02) are the standard choice.

Q3. How do I choose the legs? 2.0 mm legs are standard for direct patching; 0.9 / 1.6 mm are on request for dense in-tray routing. Pick equal-length legs for same-side patch fields, stepped (staggered) legs where connectors land at different port rows or floors.

Q4. MOQ, lead time and custom builds? Standard builds: MOQ 2 pcs, about 7–10 days. LSZH, 0.9 / 1.6 mm legs, multimode, custom fiber / color / length / label, low-loss grade and volume orders are quoted on request; a pre-production sample can be arranged.

Ordering & Service

• Standard builds: MOQ 2 pcs, about 7–10 days; custom builds (LSZH, 0.9 / 1.6 mm legs, multimode, custom fiber / color / length / label, low-loss grade) and volume orders agreed on request; reply within 24 h.
• To quote, send: fiber · fiber count · overall length · jacket (PVC standard / LSZH on request) · color · breakout leg OD (2.0 mm standard / 0.9 / 1.6 on request) · equal or stepped + leg lengths · connector / polish · labels / packaging.
• Packaging: plastic bag or winding reel; custom labels, port numbering and color bands on request; pulling eye / furcation tubing on request.
• Can be supplied as one matched set with patch enclosures, MPO cassettes and patch cords for a rack or floor build.

Focus note: We specialize in the 8–24 fiber, 3.0 mm mini breakout for indoor and ODN termination that replaces field splicing, with flexible leg and connector options. Armored, outdoor and higher-count bundled assemblies are quoted per project rather than catalogued.
