The YA 2VDT/2VDR120 series optical terminal transmits 2 10bit digital video signals + 1 control data signal through a single-mode optical fiber. The terminal video uses 10-bit digital coding technology, its high-quality video transmission standard exceeds the EIA RS-250C short-range video transmission standard; the data channel is fully compatible with RS-485/RS-422/RS-232 (ordered in advance), and adopts transparent data coding. It has a strong compatibility and is widely used in various industries such as transportation, electricity, intelligent buildings, telecommunications, warehouses, prisons, etc. The plug-and-play design makes installation extremely simple and does not require electrical or optical adjustment. This type of terminal adopts independent module and 19-inch 3RU chassis card-insert installation.
This handbook describes the YA 2VDT/2VDR120 series fiber optic transceiver, which supports two 10‑bit digital video channels (PAL, NTSC, SBCAM) and one control‑data channel. It highlights high‑precision transmission, RS‑485/RS‑422/RS‑232 compatibility, and easy plug‑and‑play installation.
Physical specifications include a 19‑inch 3RU chassis, dimensions of 245 mm × 178 mm × 28 mm, 12 VDC power input, operating temperature from –40 °C to +70 °C, and MTBF over 100 000 hours. Optical characteristics cover single‑mode 1310 nm/1550 nm wavelengths, output power >‑10 dBm, and sensitivity >‑35 dBm. Various interfaces such as BNC video, DB9 RS‑485/RS‑422/RS‑232, and TTL are provided. This manual is written in Japanese.
