40G QSFP+ ER4 40KM LC Optical Transceiver
The EQxx4X-3LCD40 is a 40G QSFP+ ER4 transceiver module engineered for long-haul optical communication, supporting up to 40 km transmission over standard single-mode fiber. It operates at a data rate of 40G, with each of its four channels delivering 11.2 Gbps, and uses CWDM technology with wavelengths at 1271, 1291, 1311, and 1331 nm as defined by ITU-T G.694.2. The module features a duplex LC connector for optical interfacing and a 148-pin electrical connector, compliant with QSFP+ MSA and IEEE 802.3ba standards for 40GBASE-ER4 links.
This transceiver integrates four un-cooled DFB lasers and a high-sensitivity APD-TIA with optical demultiplexing to ensure reliable signal integrity over extended distances. It is designed for plug-and-play functionality, with hot-swappable electrical interfaces and digital diagnostic monitoring (DDM) for real-time performance tracking. The operating case temperature ranges from 0°C to +70°C, with a 3.3V power supply and RoHS 6 compliance for lead-free construction.
Typical applications include Gigabit Ethernet, Fiber Channel, and switch-to-switch interfaces, as well as router or server connectivity in data centers and telecom networks. Buyers sourcing this module should confirm compatibility with their existing infrastructure, particularly the use of SMF and LC connectors. The product is packaged individually or in 10-piece sets and shipped from Shenzhen port in China.

Sourcing 40G QSFP+ ER4 40KM LC Optical Transceiver from Etu-link Technology Co., Ltd. - China Import Guide
Before ordering, verify that the transceiver’s CWDM wavelengths (1271, 1291, 1311, 1331 nm) align with your network’s existing infrastructure to avoid compatibility issues. Confirm the use of single-mode fiber (SMF) and LC connectors, as these are non-negotiable for achieving the specified 40 km reach. Additionally, ensure your equipment supports QSFP+ MSA and IEEE 802.3ba standards for seamless integration.
For logistics, confirm the shipping port (Shenzhen) and packaging options, which include individual or 10-piece sets. Discuss lead times and Incoterms with Etu-link Technology Co., Ltd., as these can vary based on order volume and destination. Payment terms should also be clarified upfront to avoid delays in shipment, particularly for bulk orders.
Quality checks should focus on validating the transceiver’s DDM functionality and compliance with RoHS 6 standards. Request test reports or certifications for the module’s optical performance, including insertion loss and return loss, to ensure it meets your network’s requirements. Inspection upon receipt should verify physical integrity, connector cleanliness, and adherence to the specified wavelength grid.
