HCS DataLight ST Simplex Metal Adapter - Multimode VFO-21101

SKU: VFO-21101

The DataLight VFO-21101 is an ST-form-factor simplex metallic coupler engineered for multimode (MM) fiber links. The metal housing offers enhanced mechanical durability for field installations and rack/patch panel environments. As a simplex adapter, it provides a single optical path and is intended for systems using standard ST connectors. Supplied in 25/box packaging, it addresses installations that require multiple couplers or spare inventory. The coupler facilitates orderly and reliable connections between patch panels, field enclosures or equipment-to-equipment segments that employ ST-connectored MM cabling. Key selection points include connector type (ST simplex), fiber type (MM) and a metallic housing when mechanical strength and longevity are priorities. Typical use cases include low- to medium-density pairing in data centers, campus networks and field distribution points where straightforward ST multimode coupling is needed.
