Connector Types

Optical connectors ensure efficient and reliable connections between fiber-optic patch cables. Connectors are designed to minimize insertion loss and back reflection, ensuring high-quality signal transmission.

Juniper coherent optical transceivers support the following connector type:

• Duplex Lucent Connector (LC)—A duplex LC connector is a type of connector that has small form factor and high-density design. The term duplex indicates that the connector houses two separate fiber-optic channels or lanes within a single unit. One channel is for transmission (Tx) and the other is for reception (Rx). The Tx and Rx channels enable full-duplex, bidirectional communication over a single connector. The typical LC interface is half the size of the traditional standard connector. The smaller size allows greater port density in patch panels and transceivers.

  Duplex LC/UPC is a duplex LC connector where each optical fiber end-face is polished using the ultra physical contact (UPC) method. For example, JCO400-QDD-ZR uses duplex LC/UPC connectors.

  Note: Coherent DWDM optical transceivers such as JCO400-QDD-ZR, JCO400-QDD-ZR-M, JCO400-QDD-ZR-M-HP, and JCO800-QDD-ZR-M-HP use Duplex LC connectors for their optical connections.
