V1809P — 1×9 PoF Power Splitter
A 1×9 PoF power splitter that combines a PLC optical splitter and a 48 V DC power distributor in one enclosure. It feeds eight PoF ONUs at up to 12 W each to 200 m and provides a cascade port for a second splitter.

What this model is for
1×9 PoF Power Splitter
Specifications are taken from the model datasheet. Final configuration is confirmed on the quotation.
V1809P is the distribution point of a Power-over-Fiber network. One hybrid cable arrives from the gateway; eight hybrid cables leave to ceiling APs, cameras or readers. Inside the box, a 1×9 PLC splits the optical signal and a 48 V bus splits the DC power.
The optical ratings are the ones that matter for the link budget: ≤16.5 dB insertion loss on each output, ≤2.3 dB on the cascade port, 1260–1650 nm operating range and a choice of SC/UPC or SC/APC connectors. The power side is rated 48 V DC in and out, 0.25 A nominal and 0.5 A maximum per port, from a 120 W adapter.
At 48 V, 0.25 A is 12 W; the 0.5 A ceiling is a short-term limit, not a continuous load rating. Mount it on a wall or a desktop near the gateway, keep the hybrid cable bends above the minimum radius and label each output with the AP or camera it feeds.

Engineering highlights
What changes on site.
Optical and power in one node
One enclosure splits the light and the 48 V bus, so the installer terminates one input and eight outputs instead of building a separate power distribution board.
Cascade without a second headend
The cascade port drives a second splitter for 16 APs. It adds ≤2.3 dB, far less than a second home-run fibre.
Per-port protection
Each output is current-limited. A short on one drop does not remove power from the other seven.
Small enough for a riser
180 × 120 × 26 mm, wall or desktop mount. It fits a telecom box, a riser cupboard or the back of a ceiling access panel.
Standard 48 V ecosystem
48 V DC input matches common PoE supplies and battery plants; the output is compatible with 802.3af/at loads through the PoF ONU.
Labelled outputs
Number each output and record it on the as-built. Fault finding on a PoF floor starts with the port number, not with a tone probe.

V1809P: questions before the order
If your question is not here, send the site details and we will answer with the calculation, not a brochure.
Ask an engineerIs this the same as a PLC optical splitter?
It contains a 1×9 PLC, but it also distributes 48 V DC. A standard PLC splitter only splits light and cannot power a PoF ONU.
How much power reaches the ONU at 50 m?
The port is rated 12 W at 48 V. At 50 m the copper loop resistance reduces the voltage; the ONU input range and the cable cross-section decide the usable power. Use the cable resistance from the datasheet and leave 20% headroom.
Can I mix PoF and standard PON ONUs on the same splitter?
The optical outputs can feed standard ONUs, but only PoF ONUs accept power over the hybrid cable. A standard ONU needs its own DC adapter.
What connector polish should I order?
Choose SC/UPC or SC/APC to match the gateway and ONU. Do not mix polish types without hybrid patch cords; a mismatch adds loss and reflection.
Does the splitter need a ground?
The enclosure is passive, but the 48 V supply and the building bonding system determine the grounding. Follow local electrical code and bond the supply return at one point only.
Can two V1809P units be cascaded?
Yes, through the cascade port. Each stage adds insertion loss, and the second splitter shares the 120 W supply budget. Calculate the optical margin and the total load before adding the second unit.

Need V1809P checked against your site?
Send the endpoint count, the longest run, the power condition and the destination. We return the optical/power budget and the quotation assumptions.
No obligation. The plan states its assumptions so your engineer can check it.
