Product Introduction
The Optitap SC/APC–SC/APC Optical Patch Cord is a single-fiber (simplex) cable assembly built around a 4.5×8.0mm flat FTTH drop cable with G657A2 bend-insensitive fiber. It is the final link between a fiber distribution point - like a FAT, MST, or pre-connectorized terminal box - and the subscriber's equipment. The connector at one end is an Optitap SC (a field-ruggedized, plug-and-play SC variant), and the other end is a standard SC/APC connector.
In plain terms: it's the drop cable you plug in at the curb-to-home boundary. You don't splice it. You don't strip it in the field. You just connect it and move on.
The 4.5×8.0mm flat profile is not an arbitrary choice. Flat drop cables are standard in FTTH last-mile deployments because they are easier to route along walls, run under door frames, or staple along baseboards without creating a tripping hazard or looking industrial. The G657A2 fiber classification means the cable tolerates tighter bend radii - as low as 10mm dynamic - which matters a lot when you're making a 90-degree turn around a door frame or running through a small conduit.
For reference, ITU-T G.657A2 is a specific international standard for bend-insensitive single-mode fiber. It is defined in the ITU-T G.657 recommendation, which covers 'Characteristics of a Bending Loss Insensitive Single-Mode Optical Fibre and Cable for the Access Network.' G657A2 allows tighter bends than the baseline G652D fiber used in trunk cables, which is why it's the right choice for subscriber drops.

Note on insertion loss: The ≤0.3 dB figure refers to the connector interface only. Total cable assembly IL = (2 × connector IL) + (fiber IL per km × cable length in km). For a 10m cable using standard G657A2 fiber (~0.4 dB/km at 1310nm), the added cable loss is under 0.005 dB - effectively negligible.

About the IEC standards cited above: IEC 61300-2-4 and IEC 61300-2-5 are part of the IEC 61300 series - the international testing framework for fiber optic interconnecting devices. IEC 61300-2-4 covers tensile strength testing for fiber assemblies; IEC 61300-2-5 covers compressive (crush) load testing. When a manufacturer cites these, it means the product has been measured against a globally recognized protocol, not an internal benchmark.

Key Features
Plug-and-play deployment - no splicing, no field polishing, no special tools required
Double-locked anti-vibration design on the Optitap connector keeps the link stable in high-vibration environments such as rooftop equipment and cell towers
Easy on/off: the connector can be installed and removed without damage to the fiber or housing - important when you need to re-route or replace a drop
LSZH jacket: low smoke, zero halogen - required in many building codes for indoor routing
G657A2 bend-insensitive fiber: handles tight bends in real-world routing paths without signal degradation
Wide temperature range: rated for outdoor use from -20°C to +70°C (optical spec), making it suitable for most climates
Application
This Optical Patch Cord works in both outdoor and indoor environments. The most common uses are:
FTTH last-mile drops: connecting the fiber access terminal (FAT) or multi-service terminal (MST) to the subscriber's ONT or indoor terminal box
Cell tower / Remote Radio Head (RRH) connections: the ruggedized Optitap connector was specifically designed for outdoor base station environments where vibration, moisture, and temperature swings are daily realities
Distribution box to RRH links: short fiber runs between outdoor distribution cabinets and the radio hardware mounted on a tower or rooftop
Waterproof SC port equipment: compatible with outdoor SC/APC ports on weatherproofed fiber equipment
