InLine kuitu-simplexkaapeli FTTH SC/APC 8° – SC/APC 8° 9/125µm OS2 25 m

InLine Fiber Optical Simplex Cable FTTH SC/APC 8° to SC/APC 8° 9/125µm OS2 25 m is a singlemode simplex patch cable designed for FTTH and in-building fiber connections. The cable uses OS2 9/125 µm fibre and SC/APC 8° polished connectors on both ends to provide low insertion loss and high return loss for reliable transmission over longer distances. With a 25 m length and a 3.0 mm armoured outer diameter, this white cable is intended for visible residential or enterprise installations where a durable, discreet interconnection between the building demarcation point and the fiber modem or patch panel is required.

Advantages

This InLine FTTH cable combines a singlemode OS2 fibre with APC-polished SC connectors to minimise insertion loss (typical <0.20 dB) and ensure high return loss (>60 dB). The armoured construction with a flexible stainless-steel spiral tube increases mechanical protection compared with thin pre-installed leads, while the halogen-free outer jacket and robust 3.0 mm diameter provide better longevity and safer handling during installation. The neutral white sheath supports unobtrusive routing in living spaces.

Suitable for

• FTTH connections between the building transfer point and an optical modem or ONT
• Indoor patching and backbone links in residential or small enterprise networks
• Longer indoor runs where low loss and high return loss are required
• Installations requiring a discreet white cable with mechanical reinforcement

When it may not be suitable

This cable is a singlemode OS2 simplex lead with SC/APC connectors and is not suitable for multimode systems or networks that require duplex fibre pairing. It also uses fixed SC/APC terminations; if your equipment uses different connector types (LC, ST, or SC/UPC) you will need adapters or different patch cords. For outdoor, direct-burial or duct environments specifically requiring UV-stable or gel-filled loose tube cables, choose a cable rated and specified for those external conditions.

Key specifications

• Fibre type: Singlemode OS2, 9/125 µm
• Connector type: SC/APC 8° to SC/APC 8° (both ends)
• Cable length: 25 m
• Outer diameter (armoured): approx. 3.0 mm ±0.2 mm
• Insertion loss (typical): <0.20 dB; guaranteed IL <0.30 dB
• Return loss: >60 dB
• Operating temperature range: -40 °C to +85 °C
• Sheath colour: White; halogen-free outer jacket
• Construction: single core with flexible metal (stainless steel) tubing for reinforcement

How to use

Route the 25 m InLine SC/APC simplex cable between the fiber demarcation point or patch panel and the optical modem/ONT. Ensure connectors and adapter ports are clean before mating to avoid contamination-related loss; use appropriate cleaning tools or wipes for APC-polished ferrules. Gently insert SC/APC connectors into matching APC ports until the latch engages, avoiding sharp bends (maintain minimum bend radius recommended for 3.0 mm armoured cable). After installation, verify link performance using an optical power meter or test report to confirm insertion loss and return loss meet system requirements.

What to consider before purchase

• Verify that your equipment uses SC/APC 8° ports; adapters or different connectors may be required otherwise
• Confirm singlemode OS2 fibre is compatible with your network and not a multimode system
• Choose an appropriate length (25 m) and check routing to avoid excess slack or tension
• Consider whether an armoured indoor cable is sufficient or if outdoor/duct-rated cabling is needed for external runs

Recommendations

Use fibre cleaning tools for APC connectors before each connection, avoid tight bends and excessive tensile force during routing, and, after installation, perform optical loss measurements to document link performance and ensure the cable meets IL and RL specifications.
