Choose by Transceiver

Application	Fibers	Harness
40G / 100G SR4 → 4×10G / 25G	8 (4T / 4R)	MPO-8 → 4× LC duplex
12 duplex LC channels / cassette plant	12	MPO-12 → 6× LC duplex (standard)
200G / 400G SR8 → 8×25G / 50G	16 (8T / 8R)	MPO-16 → 8× LC duplex (on request)
Base-12 plant → 3× SR4 ports	24 = 3×8	2× MPO-12 → 3× MPO-8 conversion (on request)

Send the transceiver model or channel plan and we confirm fiber count, gender, polarity and the LC leg mapping.

Harness Range

• XHT-D02-F12 · MPO-12 → 6× LC duplex — standard anchor for cassette plants and 12 duplex channels.
• XHT-D02-F08 · MPO-8 → 4× LC duplex — SR4 switch breakout to 10G / 25G servers; the most-used SME / edge build.
• XHT-D02-F16 · MPO-16 → 8× LC duplex — 200G / 400G SR8 breakout, on request.
• XHT-D02-C128 · 2× MPO-12 → 3× MPO-8 — reuses a Base-12 backbone (24 fibers) on three Base-8 SR4 ports; built to order, polarity and fiber map confirmed and supplied.
• Other conversion maps are quoted per project, not catalogued.
• Duplex standard · LC simplex on request for splice / panel termination, BiDi, PON / CATV and test ports · LC Uniboot on request → XHT-D06.

Polarity & Gender

• Gender: MPO end is female (unpinned) by default — transceiver ports and male cassette modules are pinned. Order a male end only when the mating port is female.
• Polarity: Type B (key-up / key-up) default for direct transceiver breakout. Type A made on request only to match an installed Method-A cassette plant. Type C not offered.
• Fine adjustment: the duplex clip, or the Uniboot option, flips the two LC positions on site. If unsure, send the transceiver model or channel plan.

Quality You Can Verify

• Low-loss MPO ferrules are 100% 3D-screened (fiber height, radius, apex) per ferrule; LC legs are selected to ≤0.2 dB.
• End faces inspected and cleaned per IEC 61300-3-35 and sealed with dust caps; attenuation and return loss measured per IEC 61300-3-4 / -3-6.
• Each assembly ships with a serial-numbered report and a per-fiber polarity / channel map; conversion harnesses include the Base-12→Base-8 cross-reference.
• Standard-grade builds (on request) are 100% end-face inspected and IL/RL tested; 3D geometry on sample or request.

FAQ

Q1. Fan-out harness or cassette? Direct breakout where the optic supports it → harness, no cassette. Structured, scalable patching with MACs → cassette + MPO trunk (XHT-D01 / XHT-D07).

Q2. Male or female MPO end? Transceiver ports and male cassette modules are pinned, so the harness is female. Order male only into a female mating port.

Q3. Which polarity? Type B for direct transceiver breakout (default); Type A only to match a Method-A cassette plant. The duplex clip or Uniboot can flip a pair on site.

Q4. 8, 12 or 16-fiber? Follow the optics (table above); send the transceiver model and we confirm.

Q5. Stock and MOQ? Made to order, MOQ 2 pcs, about 7 days; on-request and volume orders quoted per project.

Ordering & Service

• Made to order, MOQ 2 pcs, standard build about 7 days; on-request configurations and volume orders agreed per project.
• To quote, send: transceiver / rate · fan-out (8 / 12 / 16) · LC duplex / simplex · fiber · jacket · MPO gender / polarity · leg length · labels. We return a complete BOM and channel map; pre-production sample on request; reply within 24 h.
• Harnesses can be supplied as one matched set with MPO trunks, cassettes and patch panels for a rack build.

Focus note: We specialize in 8 / 12-fiber MPO-to-LC fan-out for SME and edge switch breakout, plus the common Base-12→Base-8 (2×MPO-12 → 3×MPO-8) migration as a made-to-order harness. 16-fiber is on request. MPO-24, Base-8→Base-4, large bundled assemblies and hyperscale conversion matrices are project-specific and not catalogued. Gender, polarity and the fiber map are confirmed before build.
