Extralink SC/APC–SC/APC patchcord, single-mode simplex G.657A1, 3 mm, 0.5 m

Extralink SC/APC–SC/APC patchcord is a single-mode simplex fibre jumper designed for short indoor and FTTH connections. The cable uses G.657.A1 fibre with a 3 mm jacket and is terminated with SC/APC connectors on both ends. At 0.5 m length, it is suitable for patching between adjacent ports in optical patch panels, connecting telecom and network equipment such as switches, media converters, and ONT/ONU devices while ensuring low insertion loss and high return loss typical of APC terminations.

Advantages

The G.657.A1 fibre specification ensures improved bend performance for installations with tight-radius routing requirements. SC/APC connectors provide stable physical contact and low back-reflection, which helps maintain signal integrity in single-mode links. The 3 mm jacket adds mechanical protection and ease of handling during installation and patching operations. The simplex configuration and short 0.5 m length reduce excess fiber slack in dense patching environments.

Suitable for

• Indoor patch panels and optical distribution frames
• FTTH termination between OLT and ONU/ONT devices
• Interconnections between SC/APC ports on switches, media converters and transceivers
• Short links where tight bend radius and low profile cabling are required

Key specifications

• Fibre type: single-mode G.657.A1
• Connector type: SC/APC to SC/APC (simplex)
• Cable diameter: 3 mm
• Length: 0.5 m
• Application: indoor, FTTH patching and short interconnects

How to use

Install the patchcord by inserting each SC/APC connector into the corresponding SC/APC receptacle until it clicks. Avoid sharp bends and excessive twisting during routing; the G.657.A1 fibre tolerates tighter bends but standard handling practices should be observed. For patch panel mounting, route the 0.5 m cable to the adjacent port or equipment interface to minimise slack and maintain clear cable management paths. Inspect connector endfaces with a fibre microscope if experiencing unexpected loss or reflections.

Usage recommendations

Store and handle the patchcord in a clean environment to prevent contamination of connector endfaces. Use dust caps when connectors are not plugged in and perform endface cleaning before mating. For permanent links or longer runs use appropriately rated cables; reserve this 0.5 m simplex patchcord for short interconnects and patching tasks.
