Buy & Import 100G DWDM QSFP28 80km PAM4 Transceiver from Guangzhou Fiberwdm Electronic Technology Co., Ltd. - Wholesale Supply

Guangzhou Fiberwdm Electronic Technology supplies this 100G DWDM QSFP28 transceiver built for long-haul dense wavelength division multiplexing links, reaching up to 80km on G.652 single-mode fibre when paired with a transport white box. The module uses PAM4 modulation on a 100GHz ITU DWDM wavelength grid, with a cooled EML transmitter operating at 2x27.5 Gbaud/s and a pin-PD ROSA receiver at the same symbol rate. It integrates soft-decision forward error correction (SFEC) with high coding gain to maintain signal integrity across extended distances.

The transceiver conforms to the QSFP28 MSA form factor and is hot pluggable, drawing from a single +3.3V supply across an operating case temperature of 0°C to 70°C. Electrical connectivity uses a 4x25G CAUI4 interface, and the optical side terminates via a dual CS adaptor. The module is RoHS6 compliant, meeting current EU hazardous substance restrictions. Typical QSFP28 DWDM modules in this class weigh approximately 80 to 100 grams and consume between 3.5W and 5W, though the listing does not state exact figures for this unit.

This transceiver targets telecom carriers, long-haul data centre interconnect operators, and enterprise networks requiring 100G transport over metro or regional distances without intermediate amplification. Buyers deploying open line systems or disaggregated optical networks will find the dual CS connector and white-box compatibility particularly relevant. Pricing, MOQ, and lead time are not listed, so procurement teams should contact Guangzhou Fiberwdm directly to confirm availability, volume discounts, and whether the module ships with individual test reports.

Frequently Asked Questions About 100G DWDM QSFP28 80km PAM4 Transceiver from Guangzhou Fiberwdm Electronic Technology Co., Ltd.
PAM4 (four-level pulse amplitude modulation) encodes two bits per symbol, allowing 100G transmission using two 27.5 Gbaud/s channels rather than four 25G NRZ lanes. This reduces the number of optical carriers needed and improves spectral efficiency on the DWDM grid. The trade-off is higher sensitivity to noise, which is why this module integrates SFEC to compensate.

Sourcing 100G DWDM QSFP28 80km PAM4 Transceiver from Guangzhou Fiberwdm Electronic Technology Co., Ltd. - China Import Guide

Before ordering this 100G DWDM QSFP28 transceiver from Guangzhou Fiberwdm, confirm the exact DWDM channel or tunable range matches your existing optical line system. DWDM networks are channel-specific, and a mismatch between the transceiver wavelength and the mux/demux port will result in a non-functional link. Ask the supplier for a full channel plan and whether the module is fixed-wavelength or tunable.

The supplier ships from Guangzhou, Guangdong, China. Lead time is not specified, so request current stock levels and production timelines before committing to project schedules. For bulk orders, clarify incoterms (FOB Guangzhou is a common starting point), carton dimensions and weights for freight quotation, and whether the supplier provides RoHS6 and CE compliance certificates with each shipment. Customs classification under HS code 8517.62 is typical for optical transceiver modules, but confirm with your customs broker.

Quality assurance for long-haul DWDM modules should go beyond basic power-on testing. Request that Guangzhou Fiberwdm provide per-unit optical spectrum analysis data, BER test results at the rated 80km distance, and DDM calibration verification. For orders intended for carrier-grade networks, ask whether the supplier can support incoming quality inspection (IQC) at their facility or provide extended warranty terms. Establishing these requirements before the first order reduces the risk of field failures in production links.
