Features

The 1G-SFP-U34-20 is a high-performance BiDi SFP transceiver designed for Gigabit Ethernet applications over single-mode fiber (SMF). Operating at wavelengths of 1310nm for transmitting data and 1490nm for receiving data, it enables bidirectional communication over a single fiber strand. Compliant with the IEEE 802.3z Gigabit Ethernet standard and SFP Multi-Source Agreement (MSA), this transceiver supports data rates of up to 1.25Gbps and achieves transmission distances of up to 20 kilometers. It is ideal for point-to-point links, metropolitan area networks (MANs), and enterprise network backbones.

FAQs

Which fiber optical cable should I use with this transceiver?

If the SFP at one end is a BiDi SFP 20Km 1.25G Tx1490/Rx1310nm LC, is the wavelength at the opposite end only Tx1310/Rx1490nm?

What are the advantages and applicable scenarios of BIDI modules compared to conventional modules?

Can these modules be used at distances ≤ 10km and ≤ 20km?

Please tell me whether DOM is supported?
