Fiber Optic Patch Cord MACLEAN SC/APC to SC/UPC Single Mode 9/125 G657A2 LSZH 3m Simplex

MACLEAN Fiber Optic Patch Cord SC/APC to SC/UPC Single Mode 9/125 G657A2 LSZH 3m Simplex is a single-mode connection cable designed for low-loss optical links. The cable pairs an angled SC/APC connector with a standard SC/UPC connector on a 3-meter simplex fiber with 9/125 µm core/cladding. Constructed with G.657.A2 bend-insensitive fiber and a low-smoke, zero-halogen (LSZH) outer jacket, this patch cord is suited for indoor telecom, data centre and patch panel environments where improved bend performance and regulatory-compliant cabling materials are required.

Advantages

The G657A2 bend-insensitive fiber reduces macro-bending loss and maintains stable optical performance in constrained routing conditions. The combination of SC/APC and SC/UPC connectors offers compatibility between equipment using angled-polish and flat-polish terminations, ensuring low return loss on the APC end and reliable mating on the UPC end. The LSZH jacket reduces smoke and halogen emissions in case of fire, meeting indoor safety requirements. A 3 m simplex build provides a compact, single-fiber link that is easy to route in patch panels and equipment racks.

Suitable for

• Telecommunications lines and single-mode optical links
• Data centre patch panels and equipment interconnects
• FTTx and access networks with space-constrained routing
• Optical links requiring a mix of APC and UPC terminations

Key specifications

• Fiber type: single-mode 9/125 µm
• Fiber standard: bend-insensitive G.657.A2
• Connector A: SC/APC (angled polish)
• Connector B: SC/UPC (ultra-polished flat)
• Configuration: simplex (single fiber)
• Cable length: 3 m
• Jacket material: LSZH (low-smoke, zero-halogen)

How to use

Connect the SC/APC end to the device or patch panel port specified for angled-polish connectors and insert the SC/UPC end into the corresponding flat-polish port. Ensure connectors are clean before mating to avoid contamination-related loss; use appropriate fiber cleaning tools and visual inspection. Route the cable without sharp bends and respect the manufacturer's minimum bend radius for G.657.A2 fiber to maintain low attenuation. For patching, secure the simplex cord in panel management clips or cable ties that do not compress the fiber.

Использование и рекомендации

For optimal performance, perform insertion loss and return loss tests after installation and keep spare protective caps on unused connectors. Avoid tight coils and direct mechanical stress on the connector boot; replace the cord if connector endfaces are scratched or permanently contaminated.
