The Pan Pacific Harmonica Jacks category narrows the Fiber Optics & Telco Breakout family to a specific fiber-optic connectivity format, helping match the mechanical interface before choosing a part number. Examples currently represented in Wallco's Pan Pacific catalog include DC-HJ-12P4CF-USOC (DC-HJ-12P4CF-USOC Harmonica Jacks 12Port Female Telco Usoc) and DC-HJ-12P4CM-USOC (DC-HJ-12P4CM-USOC Harmonica Jacks 12Port Male Telco Usoc).
For this Pan Pacific category, verify fiber type (single-mode or multimode), connector style, simplex/duplex construction, polish/interface where applicable, length and optical link requirements. Those attributes determine mating compatibility and whether the part is appropriate for the intended equipment or cabling system.
The catalog path is Pan Pacific > Voice / Data Components > Fiber Optics & Telco Breakout > Harmonica Jacks. Keeping the manufacturer family, parent interface and exact subcategory together is useful for distinguishing parts that share a similar appearance but use different termination, wiring, impedance, contact or mounting details.
Start with the existing Pan Pacific part number when replacing a component. If it is unavailable, document the mating equipment and the key attributes for harmonica jacks: fiber type (single-mode or multimode), connector style, simplex/duplex construction, polish/interface where applicable, length and optical link requirements.
Wallco currently has 10 active Pan Pacific products assigned to this category in the latest catalog export. The category is intended to narrow the choice; final compatibility should be confirmed at the individual part level.
Do not assume that two products in the harmonica jacks family are interchangeable solely because they share a connector family. Pinout, impedance, shielding, termination, shell size, wiring standard or signal direction may differ depending on the interface.
Compare fiber type (single-mode or multimode), connector style, simplex/duplex construction, polish/interface where applicable, length and optical link requirements.
Match the complete Pan Pacific part number first. If cross-referencing, compare the mating interface, mechanical format, termination/wiring and electrical or signal requirements before substituting another model.
