NO NAME M-207M Σετ μετατροπέα μέσων Single-Mode BiDi Fast Ethernet, SC Simplex, 20 km, 10/100 Mbps, μέταλλο, μαύρο

For point-to-point fibre links where installing additional cabling is impractical, the M-207M pair delivers a complete single-mode solution in one box. Unlike conventional two-fibre converters, this set uses bi-directional (BiDi) optics over a single SC simplex fibre, cutting fibre usage in half while maintaining a full 20 km reach. Each unit is pre-paired with complementary wavelengths—1310 nm transmit / 1550 nm receive on one side and the reverse on the other—so no configuration is needed. Simply connect your existing 10/100 Mbps Ethernet devices to the RJ45 ports, link the two converters with one single-mode fibre, and traffic flows transparently.

Highlights

• Complete set: two media converters pre-matched for bi-directional single-fibre operation
• Single-mode SC simplex connection supports distances up to 20 km
• Fast Ethernet 10/100 Mbps auto-negotiation on the copper port
• Auto MDI/MDI-X eliminates the need for crossover cables
• Full/half duplex support with flow control (IEEE 802.3x)
• Sturdy metal housing for reliable heat dissipation and durability
• External DC 5V/1A power adapters included for both units
• LED indicators for power, fibre link/activity, copper link/activity, and duplex/collision status

In daily use

The M-207M is built for straightforward deployment in enterprise networks, campus backbones, or any scenario where copper Ethernet must cross a long distance over existing single-mode fibre. Because the pair is matched at the factory, there is no risk of wavelength mismatch—just plug in the fibre and power. The metal chassis withstands typical wiring closet conditions, and the compact desktop form factor fits easily on a shelf or desk. Jumbo frames up to 1536 bytes pass through without fragmentation, preserving performance for large data transfers. With an operating range of 0 °C to 50 °C and 5–90% non-condensing humidity, it handles most indoor environments reliably.
