Fibre Optic Connector LC Female/Female Alcasa LW-K203

The Alcasa LW-K203 LC Female/Female fibre optic connector by Good Connections is designed for OM3 multimode fibre links where low insertion loss and compact form factor are required. This inline adapter provides a stable mechanical connection between two LC male connectors, preserving signal integrity for high-speed data transmission in networking and telecommunications environments. Its robust housing and precise alignment sleeves support consistent performance in rack-mounted equipment, patch panels and tight-access installations.

Advantages

The LC Female/Female design reduces the need for custom cabling and enables flexible reconfiguration of fibre networks without splicing. Precision ceramic alignment sleeves ensure minimal insertion loss and low back reflection, while the compact dimensions save space in dense patch fields. The durable outer body resists wear from repeated mating cycles, supporting maintenance and upgrades with predictable optical performance.

Suitable for

• OM3 multimode fibre patch panels and trunking
• Data centres and server rooms with high-density cabling
• Telecommunications equipment and network closets
• Lab testing and temporary fibre connections

Key specifications

• Connector type: LC female to LC female (duplex compatible)
• Fibre compatibility: OM3 multimode
• Alignment sleeve material: ceramic (precision)
• Typical insertion loss: low (engineered for minimal loss)
• Return loss: suitable for multimode applications
• Housing: compact, durable construction for high-density environments
• Operating environment: indoor telecom and data centre use

How to use

Insert the LC male connector from each fibre cable into the corresponding LC female ports of the LW-K203 until a positive latch is felt. Ensure connectors and ferrules are clean before mating to avoid contamination-related loss; use appropriate fibre cleaning tools if necessary. Mount the adapter in a patch panel or leave inline for temporary connections, observing bend radius limits of the connected OM3 fibre to maintain signal quality. When disconnecting, press the LC latch and gently withdraw to avoid damaging the connector or fibre.

Usage recommendations

Regular inspection and cleaning of connector endfaces are recommended to preserve low insertion loss. Use in indoor, controlled environments and avoid exposure to moisture and excessive mechanical stress. For optimal performance in high-speed links, pair with OM3-rated cables and maintain proper patching practices in dense installations.
