ETERN Optoelectronics 40G QSFP+ SR4/CSR4 100m-300m Optical Transceiver
The 40GBASE-SR4 series from ETERN Optoelectronics supports high-bandwidth optical links over 12-fiber parallel fiber terminated with MPO/MTP connectors. These transceivers are optimized for laser-optimized OM3, OM4, and OM5 multimode fibers, supporting distances of 100m (SR4) and up to 300m (CSR4).
A key feature of the FLS40C101S/FLS40C103S is the 4x10G breakout mode. This allows interoperability with 10GBASE-SR and SFP-10/25G-CSR-S interfaces using an external breakout cable. The modules are specifically engineered to prevent receiver overload or false alarm triggers during 4x10G operation, ensuring a "worry-free" transition between 40G and 10G network segments.
Key Technical Highlights
- Dual Distance Options: Choice between standard 100m (SR4) and extended 300m (CSR4) reach over OM4 fiber.
- Interoperable Breakout Mode: Seamlessly connects to four 10GBASE-SR interfaces via 12-fiber to 2-fiber breakout cables.
- Receiver Protection: Optimized optical characteristics prevent overload when interfacing with 10G components.
- Highly Efficient: Ultra-low power consumption of less than 1.5W.
