1×4 PLC Singlemode Splitter

The Vszerda SC UPC 1×4 PLC splitter divides a single singlemode fibre into four equal outputs for FTTH, LAN or telecom distribution. It uses G657A1 bend-insensitive fibre in a stainless-steel module. Installers running point-to-multipoint passive optical networks will find the 1 m pigtail length convenient for splice trays. Buyers needing a 1×8 or 2×4 split ratio cannot use this module.

Insertion loss 7.5 dB return loss 50 dB

The key specification is the guaranteed maximum insertion loss of 7.5 dB combined with a minimum return loss of 50 dB across the 1260 nm to 1650 nm window. These figures determine whether the link budget supports the planned split distance and ONT sensitivity. Designers who require lower loss for longer reaches must select a different splitter grade.

0.9 mm pigtails SC UPC connectors

Each of the five fibres terminates in a 0.9 mm buffered pigtail with an SC UPC ceramic ferrule, so the unit plugs directly into patch panels or closure trays without extra fan-out kits. The stainless-steel housing protects the PLC chip from -40 °C to 85 °C. Users who need ruggedised 2 mm or 3 mm cable jackets must add separate protection.

Questions about this item

What does the 7.5 dB insertion loss mean for signal strength in a live link?

Each of the four output ports adds roughly 7.5 dB of attenuation, so the downstream power budget must accommodate that loss per split path.

How does the SC-UPC connector interface limit return loss in practice?

The UPC polish provides a 50 dB return loss figure, keeping reflected light low enough for stable singlemode transmission.

What physical space does the 0.9 mm G.657A1 pigtail need for routing and bending?

The 0.9 mm bare fibre with G.657A1 rating supports tight bends down to a few millimetres radius, easing installation in splice trays or wall boxes.
