The 1G Single Mode SFP Transceiver Module (1GSFP-SM20K) is a compact, high-performance solution for bi-directional serial optical data communications, such as Gigabit Ethernet 1000BASE-LX. It features a small form-factor pluggable (SFP) 20-pin connector, allowing for easy hot-plug capability. Designed for single-mode fiber, this module operates at a nominal wavelength of 1310nm. The transmitter utilizes a multiple quantum well 1310nm laser, compliant with class 1 laser safety standards (IEC-60825). The receiver incorporates an integrated InGaAs detector preamplifier (IDP) with a limiting post-amplifier IC, ensuring high-quality signal reception. The 1GSFP-SM20K is fully compliant with the SFF-8472 SFP Multi-Source Agreement (MSA), guaranteeing compatibility with other compliant devices. Ideal for long-distance communication, this module offers reliable and efficient data transfer over single-mode fiber.
