Fiber Optic Patchcords: The Complete Guide for Lebanon
Fiber optic patchcords are the short, pre-terminated cables that connect your SFP modules to patch panels, OLTs to splitters, and ONTs to wall outlets. Choosing the wrong connector type, polish, or length wastes time and money — and in Lebanon, where fiber deployments are accelerating across Beirut, Mount Lebanon, and major cities, technicians need to stock the right patchcords before arriving at a job site.
HI-GAIN stocks over 13 fiber patchcord SKUs at our Dora, Beirut warehouse, covering every connector combination used in Lebanese FTTH, ISP backbone, and enterprise deployments. This guide explains the differences and helps you order the correct cable the first time.
Connector Types: LC vs SC vs SC/APC
Three connector types dominate the Lebanese fiber market:
LC (Lucent Connector)
The LC connector uses a 1.25mm ferrule — half the size of an SC connector. It is the standard connector on virtually all SFP and SFP+ modules. If you are connecting a MikroTik router's SFP port, a CRS switch's SFP+ cage, or a Ubiquiti device's fiber port to a patch panel, you need an LC connector on the equipment end. LC connectors use a push-pull latching mechanism that clicks into place.
SC (Subscriber Connector)
The SC connector uses a 2.5mm ferrule and a push-pull coupling mechanism. SC connectors are standard on OLTs (Optical Line Terminals), media converters, older patch panels, and many FTTH ONTs. They are physically larger than LC but easier to handle with gloved hands or in tight spaces. In Lebanese FTTH deployments, the ONT (fiber box) at the customer premises almost always has an SC port.
SC/APC (Angled Physical Contact)
The SC/APC connector is an SC connector with the fiber end-face polished at an 8-degree angle. This angle directs reflected light away from the fiber core, achieving return loss better than -60 dB (compared to -50 dB for standard UPC polish). SC/APC connectors are green — the color coding is an international standard and makes them easy to identify. They are mandatory on GPON ODN (Optical Distribution Networks) from the OLT through splitters to the ONT. Most Lebanese ISPs deploying GPON require SC/APC on the distribution side.
Critical rule: Never mate an APC connector with a UPC/PC connector. The 8-degree angled face of an APC connector does not make flat contact with a UPC/PC connector. The result is extreme insertion loss (3+ dB), high return loss, and potential damage to both ferrule surfaces. APC connects only to APC. UPC/PC connects to UPC/PC.
Polish Types: PC vs UPC vs APC
| Polish Type | End-Face Shape | Return Loss | Color Code | Typical Use |
|---|---|---|---|---|
| PC (Physical Contact) | Slightly curved | -40 dB | Blue | General data networking, switches, routers |
| UPC (Ultra Physical Contact) | More precisely curved | -50 dB | Blue | Data networking, SFP modules, point-to-point links |
| APC (Angled Physical Contact) | 8-degree angle | -60 dB or better | Green | GPON/FTTH, CATV, analog video, long-haul WDM |
PC and UPC connectors are intermateable — they will work together with performance determined by the lower-spec connector. APC is never compatible with PC or UPC. Mixing them damages both connectors.
HI-GAIN's Fiber Patchcord Inventory
Here is every patchcord we stock, organized by connector combination and length:
LC/PC to LC/PC (Single-Mode Simplex)
The most common patchcord for connecting SFP modules to patch panels or directly between two SFP-equipped devices:
| Product | Length | Use Case |
|---|---|---|
| LC/PC - LC/PC SM 3m | 3 meters | Rack-to-rack inside server room, SFP to patch panel |
| LC/PC - LC/PC SM 10m | 10 meters | Cross-room patch, between adjacent racks |
| LC/PC - LC/PC SM 30m | 30 meters | Floor-to-floor within building, long corridor runs |
| LC/PC - LC/PC SM 50m | 50 meters | Building-to-building short runs, large office floors |
SC/PC to LC/PC (Single-Mode Simplex)
The hybrid patchcord connecting SC-terminated patch panels or ONTs to LC-terminated SFP modules. This is the most-ordered combination in Lebanese FTTH installations — the ONT or wall plate has SC, and the router/switch SFP has LC:
| Product | Length | Use Case |
|---|---|---|
| SC/PC - LC/PC SM 3m | 3 meters | ONT to router in same rack or desk area |
| SC/PC - LC/PC SM 3m (Dual) | 3 meters (pair) | Duplex BiDi link using two simplex patchcords |
| SC/PC - LC/PC SM 10m | 10 meters | Patch panel to distant switch within server room |
| SC/PC - LC/PC SM 50m | 50 meters | Floor-to-floor or building entry to server room |
| LC/PC - SC/PC SM 3m (1pc) | 3 meters | Same as SC-LC 3m, reversed connector labeling |
SC/APC to SC/PC (Single-Mode Simplex)
Used at the demarcation point in GPON networks where the ISP's APC-terminated distribution fiber meets the customer's UPC-terminated equipment. Note: this specific combination mates an APC connector on one end with a PC connector on the other end — each end connects to its matching port. The two ends never mate with each other.
| Product | Length | Use Case |
|---|---|---|
| SC/APC - SC/PC SM 30m | 30 meters | GPON splitter to ONT, floor-level distribution |
| SC/APC - SC/PC SM 50m | 50 meters | Building entry to apartment ONT, long FTTH drops |
Pigtails for Fiber Splicing
A pigtail is a short length of fiber (typically 1-1.5 meters) with a connector on one end and a bare fiber on the other. The bare end is fusion-spliced to the incoming cable fiber. Pigtails are essential for terminating fiber runs at patch panels, splice trays, and ODF (Optical Distribution Frame) enclosures.
- Pigtails — All Connector Types (Individual) — Available in LC/PC, LC/APC, SC/PC, SC/APC, and other connector types. Single-mode 9/125um, 0.9mm tight buffer.
- Pigtails — All Connector Types (Bulk) — Same pigtails in bulk packs of 12 or 24, color-coded for fiber identification in 12-fiber and 24-fiber cable terminations. Cost-effective for ISPs terminating multiple fiber cables at a POP.
When ordering pigtails, specify the connector type (LC/PC, SC/APC, etc.) and quantity. HI-GAIN carries the full range of connector types to match any deployment requirement.
Which Patchcord for Which SFP Module?
The patchcord connector on the equipment side must match the SFP module's port type. Here is how HI-GAIN's SFP modules pair with patchcords:
| SFP Module Type | Fiber Count | Connector on SFP | Patchcords Needed |
|---|---|---|---|
| Dual-fiber SFP (e.g., 1G 20km DDM) | 2 fibers (TX + RX) | Duplex LC/PC | 2x simplex LC-LC or 1x duplex LC-LC |
| BiDi SFP (e.g., 1G 20km WDM pair) | 1 fiber (TX + RX on different wavelengths) | Simplex SC or LC | 1x simplex patchcord matching SFP connector |
| 10G SFP+ (e.g., 10G 20km) | 2 fibers or 1 fiber (BiDi) | LC/PC | 2x simplex LC-LC or 1x simplex LC-LC (BiDi) |
| SFP to Ethernet Media Converter | N/A (copper output) | LC or SC (SFP side) | Match the SFP module's connector |

Fiber Handling Best Practices for Lebanese Installations
Fiber patchcords are glass. They perform flawlessly for decades if handled correctly, and fail immediately if abused. Follow these rules in every Lebanese deployment:
- Minimum bend radius: Never bend a single-mode patchcord tighter than 30mm (about the diameter of a marker cap). Tight bends cause micro-cracks in the glass core that increase attenuation. In crowded Lebanese server racks where space is tight, use 90-degree fiber management panels rather than forcing sharp bends.
- Keep connectors capped when not in use. Dust is the primary enemy of fiber connections. A single dust particle on a connector end-face can cause 1+ dB of insertion loss. In Lebanese construction environments with concrete dust, plaster, and general debris, always keep dust caps on unused connectors and clean end-faces with lint-free wipes before mating.
- Do not exceed the patchcord's rated length for the application. A 50m patchcord adds roughly 0.2 dB of attenuation. Combined with connector losses (0.3 dB per mated pair), a 50m run between two connectors adds about 0.8 dB total. Budget this into your link power calculations, especially on long-distance SFP links approaching their maximum rated distance.
- Label both ends. In a busy patch panel with 24 or 48 patchcords, unlabeled fiber is untraceable without an optical tracer tool. Label both ends of every patchcord with port numbers and destination at the time of installation.
