Single-Fiber Efficiency (BiDi): Unlike standard "double fiber" modules, this uses a single LC connector to both send and receive data. This effectively doubles your fiber capacity by allowing two-way communication on a single strand.

WDM Wavelength Mapping: * Transmit (Tx): 1310 nm

Receive (Rx): 1550 nm

Note: This must be paired with the matching "R" version (GSFP-1310R-20-SMF) at the other end of the link, which uses Tx 1550nm / Rx 1310nm.

Industrial Temperature Range: Rated for –40 °C to +85 °C, making it suitable for unconditioned outdoor enclosures, industrial plants, and extreme weather environments.

Long-Range Capability: Supports reliable data transmission up to 20 km (12.4 miles) over Single-Mode Fiber (SMF).

High-Speed Throughput: Operates at a standard 1.25 Gbps data rate, compliant with IEEE 802.3z 1000Base-BX standards.

Hot-Pluggable & PnP: Designed for "Plug and Play" installation; you can insert or remove the module without powering down the switch, ensuring zero disruption to other ports.
