FIBCONET fibra optica connectors et adaptors covering the full range of formats used in FTTH access, data-centre cabinets, telecom central offices and outdoor deployments — from standard SC / LC / FC / ST / MPO / MTRJ / E2000 to IP67 / IP68 IMPERVIUS outdoor-rated connectors and field-assembly (fast) connectors for on-site termination.
Every connector and adapter ships after 100% factory inspection — end-face 3D interferometer for MPO, insertion loss and return loss measurement on all fiber types, and mating durability verification against IEC 61754 et Telcordia GR-326-CORE (Genus r) methodologia. Ferrules are Sanhuan (Sumitomo on request), and connector bodies come in standard telecom grade through outdoor waterproof PEI / PDLC housings.
An adapter (also called coupler or mating sleeve) is the passive component that joins two connectors face-to-face inside an ODF panel, repeciare panel, wall plate or termination box. It aligns the two ferrules within tight concentricity tolerance so the light passes across the junction with minimum loss and reflection.
| Connector Format | Sleeve Material | Typical Insertio Damnum | Redi damnum |
|---|---|---|---|
| SC | Ceramic (zirconia) | ≤ 0.2 dB* | UPC ≥ 50 dB*; APC ≥ 55 dB* |
| LC | Ceramic (zirconia) | ≤ 0.2 dB* | UPC ≥ 50 dB*; APC ≥ 55 dB* |
| FC | Ceramic (zirconia) | ≤ 0.2 dB* | UPC ≥ 50 dB*; APC ≥ 55 dB* |
| ST | Ceramic (zirconia) | ≤ 0.2 dB* | UPC ≥ 50 dB* |
| MPO / MTP | Precision-molded polymer with pin alignment | ≤ 0.35 dB average (low-loss) | ≥ 55 dB* (APC) |
| E2000, MTRJ, MU | Ceramic | ≤ 0.2 dB* | UPC ≥ 50 dB*; APC ≥ 55 dB* |
Available in simplex, duplex and quad configurationes, with mounting flanges for standard ODF drawer, wall plate, patch panel and custom panel cutouts. Colour coding follows the industry convention — blue for UPC, green for APC, aqua for OM3/OM4, lime green for OM5, beige for OM1/OM2 — so any technician can identify the format at a glance.
Our connector line splits into three families depending on how the fiber is terminated:
| Type | Modus Cessatio | optimus For |
|---|---|---|
| Factory-Terminated Connector (polished on our patch cord line) |
Fusion-splice, epoxy + polish in factory | Repeciare funibus, pigtails, ODF pre-terminated cabling — highest and most consistent optical performance |
| Field-Assembly (Fast) Connector | Mechanical splice on-site, no fusion splicer required | FTTH field deployment, drop-cable termination, emergency repair — see our dedicated Fast Connector category for the full line |
| IMPERVIUS / Outdoor Connector (PDLC, PEI, IP67 / IP68) |
Pre-terminated cable assembly with sealed housing | Base-station RRU, outdoor equipment, telecom compatibility (HW / ZTE / Ericsson), harsh-environment interconnect |
For pre-terminated cable assemblies, connectors are integrated onto FIBCONET patch cords in-house — giving you traceable ferrule origin, insertion loss test report per core, and consistent batch performance. For field-assembly connectors, our dedicated Fast Connector category covers threaded self-locking, alligator-os, drawer-type, CCTC single-ceramic, three-ring double-ceramic and other field-installable formats used in FTTH last-mile projects.
All three describe how the ferrule end-face is polished, and each gives a different return loss value.
| Polonica Type | Redi damnum | Where to Use |
|---|---|---|
| PC (Contactus corporalis) | ≥ 40 dB* | Legacy telecom, low-cost general use — largely superseded by UPC |
| UPC (Ultra Contactum) | ≥ 50 dB* | Data centers, Enterprise Networks, most FTTH indoor cabling — the mainstream default |
| APC (Angulus Contactus, 8° polish) | ≥ 55 dB* | MON / FTTH extra plant, CATV RF super vitrum, DWDM — anywhere high return loss is critical to prevent signal reflection |
Rule of thumb: use APC (green connector) for anything carrying an RF-modulated signal or a PON drop; UPC (blue connector) for standard data traffic. Never mate UPC to APC — the polish angle mismatch will introduce significant loss and can damage the ferrules.

Standard SC / LC / FC / ST adapters and connectors ship from stock without a strict MOQ — sample and trial orders are welcome. MPO connectors typically start at 100 Unitates. Waterproof and telecom-compatible connectors (tres nostri in uno fibro opticorum velit connexionis convertentis in esse / ZTE / Ericsson) are quoted per project depending on housing spec.
A connector is the plug at the end of a fiber cable — it holds the ferrule and terminates the fiber. An nibh (also called coupler or mating sleeve) is the passive junction that joins two connectors face-to-face, aligning their ferrules for low-loss signal transfer. Every ODF, patch panel or wall plate uses adapters to receive incoming connectors from patch cords or pigtails.
Usus APC (green connector, 8° angled polish) for any PON / FTTH outside plant link, CATV RF super vitrum, and DWDM — anywhere reflected light could interfere with the signal. Usus UPC (blue connector) for standard data traffic in data centres, enterprise networks and most indoor cabling. Never mate UPC to APC — the angle mismatch causes major loss and can damage the ferrules.
Ita. Nos fabricare IP67 and IP68 waterproof connectors in PDLC and PEI housings, compatible with Huawei, ZTE, Ericsson and other major telecom equipment vendors. Please specify the target equipment model at RFQ stage so we can confirm the correct housing and interface spec.
