XHT-A04 ¡¤ FTTH / FTTR ACCESS NETWORKS
SC Field-Installable Fast Connectors (OS2)
Five field-installable models ¡¤ SC/APC and SC/UPC both standard ¡¤ from 100 pcs
Pre-polished, field-installable mechanical-splice connectors for FTTH drop termination. Choose the model that matches your cable and performance needs - no epoxy, no polish, no special tool. The five models differ in latching mechanism and alignment material; all are standard SC connectors for in-building and cabinet use.
At a Glance
Polish: SC/APC (green) and SC/UPC (blue) both standard, same MOQ. Always keep both ends the same; never mate APC with UPC.
Cable fit: flat drop 2.0 x 3.0 mm & 2.0 x 1.6 mm (all models); round drop 3.0 / 5.0 mm (model C)
Retention: model A >40 N / 2 min (threaded tail); models B / C / D / E >30 N / 2 min
MOQ & lead time: from 100 pcs, ~3-7 days; hardened waterproof SC (Mini-SC compatible / OptiTap compatible) on request, separate range
Five Models - Match to Your Project
Model A ¡¤ Push-Tube, Value Build
▪ Where it fits: high-volume, price-sensitive new FTTH builds; indoor and cabinet termination.
▪ Design: push-tube latching, integrated structure, simple and proven; engineering-plastic V-groove.
▪ Cable: 2.0 x 3.0 mm and 2.0 x 1.6 mm flat drop; tail threaded onto the cable jacket.
▪ Retention: >40 N / 2 min - the highest pull resistance of the range.
Model B ¡¤ Normally-Closed Clamp, Best Re-Entry recommended main
▪ Where it fits: professional installers and mid-size ISPs; first-time-right work with low rework.
▪ Design: normally closed elastic fastening; linkage structure keeps the reserved slight bend unchanged when connecting with equipment and joints. Good re-entry if a fiber needs re-trimming.
▪ Cable: 2.0 x 3.0 mm and 2.0 x 1.6 mm flat drop.
▪ Retention: >30 N / 2 min.
Model C ¡¤ Multi-Cable (Flat + Round)
▪ Where it fits: mixed fleets where both flat and round drop appear on the same job.
▪ Design: normally closed elastic fastening; linkage structure keeps the reserved slight bend unchanged when connecting with equipment and joints. Good re-entry if a fiber needs re-trimming.
▪ Cable: 2.0 x 3.0 mm & 2.0 x 1.6 mm flat drop, plus 3.0 mm and 5.0 mm round drop.
▪ Retention: >30 N / 2 min.
Model D ¡¤ Metal V-Groove, Stable
▪ Design: metal V-groove. The gain over plastic is stiffness and long-term stability - it does not deform or soften under temperature change, so alignment holds and loss stays stable over time.
▪ Cable: 2.0 x 3.0 mm flat drop.
▪ Retention: >30 N / 2 min.
Model E ¡¤ Box Building Structure, Strong Weather Resistance
▪ Design: metal V-groove with a box building structure that keeps the index-matching gel in place - stronger weather resistance and lower long-term drift.
▪ Cable: 2.0 x 3.0 mm flat drop.
▪ Retention: >30 N / 2 min.

Ordering, MOQ & Lead Time
▪ Models A / B / C / D / E: from 100 pcs, ~3-7 days; SC/APC and SC/UPC at the same MOQ and lead time. Sample first, then volume.
▪ Hardened waterproof SC (Mini-SC compatible and OptiTap compatible versions) is a separate range: MOQ and lead time agreed on request.
▪ Mixed models / polish in one shipment are welcome for project roll-outs.

FAQ
Q1. How do I choose between the five models?
Pick by your needs, not by "tier": need the simplest, lowest-cost volume build with the highest pull strength ¡ú A; need clean re-entry if a fiber must be re-trimmed ¡ú B; also terminate 3.0 / 5.0 mm round drop on the same job ¡ú C; want stiffer alignment and more stable long-term performance under temperature change ¡ú D; want stronger weather resistance with the gel kept in place ¡ú E. Tell us the cable and the job, we will match it.
Q2. SC/APC or UPC?
SC/APC (green) is the FTTH default for PON split and any RF overlay; UPC (blue) for equipment-side ports. Same MOQ either way. Never mate APC with UPC.
Q3. Are these waterproof / hardened?
Models A-E are standard SC connectors for in-building and cabinet use; they are not waterproof hardened connectors. For external hardened terminals we offer a separate Mini-SC-compatible and OptiTap-compatible hardened range on request.
Values are typical / max per IEC 61300-3-4 and Telcordia GR-1081; production data governed by the per-shipment factory test report. Standard, non-OEM components interoperate with standard adapters. This page covers field-installable SC fast connectors; see the drop-cable, box and test-equipment SKUs for the rest of the FTTH workflow.
