The optical port has the following characteristics: the fiber type is G.652, the typical transmission distance can reach 40 km, the TX wavelength is in the range of 1280 - 1340 nm, the RX wavelength is in the range of 1100 - 1600 nm, the TX power is from 0 to - 5 dBm, and the RX sensitivity is from - 3 to - 34 dBm.

Network Standards

• The switch adheres to IEEE 802.3 for 10Base - T, IEEE 802.3u for 100Base - T(X) and 100Base - FX, and IEEE 802.3x for flow control.

Switching Capabilities

• It has a MAC address table size of 2 kbits, which is used to store and manage the MAC addresses of connected devices.

• The packet buffer size is 768 k, enabling it to handle bursty data traffic effectively.

• It adopts the store - and - forward switching mode.

Power Supply

• Input Current: The input current is 0.12 A @ 24 VDC.

• Voltage Range: It supports an operating voltage range of 9.6 - 60 VDC. It features redundant dual - input power (12/24/48 VDC) and is equipped with reverse - polarity protection and overload - current protection. The power connector is a removable 6 - contact terminal block.

Physical Characteristics

• Housing: The housing is made of metal with an IP30 protection rating, providing good protection against dust and solid objects.

• Dimensions: The dimensions are 53.6 x 135 x 105 mm (2.11 x 5.31 x 4.13 in), making it compact and suitable for various installation scenarios.

• Weight: It weighs 790 g (1.75 lb), which is relatively lightweight for easy installation and handling.

• Installation: It can be installed on a DIN - rail or on a wall using an optional mounting kit, offering flexible installation options.

Environmental Specifications

• Operating Temperature: The operating temperature range is - 10 - 60 °C (14 - 140 °F), allowing it to operate in a wide range of environmental conditions.

• Storage Temperature: The storage temperature range is - 40 - 85 °C (- 40 - 185 °F), ensuring its durability during storage and transportation.

• Relative Humidity: The ambient relative humidity range is 5% - 95% (non - condensing), which means it can work in high - humidity environments without being affected by condensation.

Standards and Certifications

• Safety: It complies with safety standards such as UL 508, UL 60950 - 1, CSA C22.2 No. 60950 - 1, and EN 62368 (LVD).

• EMC: For EMI, it complies with CISPR 32 and FCC Part 15B Class A. For EMS, it meets the requirements of IEC 61000 - 4 - 2 ESD (contact: 6 kV, air: 8 kV), IEC 61000 - 4 - 3 RS (80 MHz - 1 GHz: 20 V/m), IEC 61000 - 4 - 4 EFT (power: 2 kV, signal: 1 kV), IEC 61000 - 4 - 5 Surge (power: 2 kV, signal: 2 kV), and IEC 61000 - 4 - 6 CS (10 V).

• Hazardous Locations: It is certified for use in hazardous locations, such as ATEX Class I Division 2.

• MTBF: The Mean Time Between Failures (MTBF) is 2,646,710 hrs according to the MIL - HDBK - 217F standard, indicating its high reliability.

Other Features

• It is equipped with a built - in relay warning function. When power failures or port failures occur, it can send out alarm signals to network administrators through relay output.

• It also has broadcast storm protection to enhance the reliability and stability of the network, preventing network congestion caused by excessive broadcast packets.

Warranty

• Usually, the MOXA EDS-308-S-SC-T comes with a 5 - year warranty, providing customers with long - term quality assurance.
