Information About ISEL-2812MT
The SEL-2812MT enables serial data communication at speeds up to 115.2 kbps over multimode fiber, supporting full-duplex operation with no jumper configuration required. It features an 850 nm VCSEL transmitter, ST fiber connectors, and compatibility with 50 to 200 µm core fiber types. The module offers IRIG-B time code support via switch-selectable DB-9 or IRIG-B jack connections. Power is drawn parasitically from DB-9 pins, and the device is housed for indoor use only, with full operational reliability between –40°C and +85°C. Its optical budget of 12 dB and robust electrical isolation make it suitable for demanding industrial applications.
Key Features:
- High-Speed Fiber Communication: Supports up to 115.2 kbps full-duplex data transfer with low latency, requiring no manual settings.
- Low Link Data Delay: Serial data delay of 6 µs + 5 µs/km of fiber; IRIG-B delay of 15 µs + 5 µs/km, ensuring accurate time synchronization.
- Robust Optical Transmission: Features an 850 nm VCSEL transmitter with a typical transmit level of –13 dBm and a receive sensitivity of –27.5 dBm.
- Flexible Power Options: Operates from DB-9 connector pins using parasitic power, drawing a maximum of only 15 mA.
- Reliable Fiber Compatibility: Uses ST connectors and supports a range of SEL fiber types including SEL-C805, C807, and C808 for multimode 50–200 μm cores.
- IRIG-B Support: Switchable IRIG-B signal routing through either a DB-9 connector or dedicated jack.
- Environmental Hardening: Operates between –40°C to +85°C and meets Insulation Class 3 and Overvoltage Category 2, suitable for utility-grade deployments.
- Compact Installation Footprint: Projects just 127 mm from DB-9 connector, accommodating minimum bend radius of fiber cables.
- EMC Compliance and Safety: Designed under ISO 9001, CE marked, UKCA marked, and compliant with FCC Class A standards.
The SEL-2812MT offers fast, interference-resistant fiber communication ideal for timing and control in substations and industrial automation.
