Multi-mode dual-fiber 2-km SC interface wavelength: 1310 nm to transmit two-way 232 data, ST/FC port is optional
Industrial RS-232 Optical Fiber MODEM
L RS-232 can support 2-way RS-232 at the same time
Note: If the equipment is single-fiber configuration, it will be divided into A and B. Only A corresponds to B can normal communication. A-A or B-B can not synchronize the optical fiber signal.
I. Concept
RS-232 interface optical fiber MODEM is the best choice to connect remote terminal unit (RTU) to host (HOST) or distributed data acquisition system (SCADA) controller. The product uses optical fiber as transmission medium.
It improves the transmission performance of the system and effectively avoids the threat of lightning, surge and electromagnetic interference to communication equipment in harsh environment.
II. Functions and Characteristics
(a) Support RS-232 interface, asynchronous transmission, point-to-point application, rate greater than > 115.2 Kbps
B) Support 5V DC power input
D) ESD protection of +/-15KV (human model), +/-8KV contact discharge
E) Self-adapting single-mode and multi-mode fibers without distinction
F) Working wavelength; 1310 nm/1550 NM
G) Automatic detection of signal rate, zero delay automatic rotation
H) Can be matched with 2U/14 slot slot card type chassis for centralized use
III. Performance parameters
Interface; compatible with EIA RS-232 standard
Transmission rate; 0-115.2 Kbps (RS232)
Transmission distance; Optical port: multi-mode 2KM, single-mode 20-120 KM
RX; Optical Fiber Signal Synchronization, Receiving Optical Signal at Frequent Bright
D1: Data signal lamp, which flickers regularly when sending and receiving data
D2: Data signal lamp, which flickers regularly when sending and receiving data
