The DWDM-SFP10G-3819-ER-C is a 10GBase-DWDM SFP+ transceiver operating at 1538.19 nm for 40 km single-mode fiber links.
It operates at a DWDM central wavelength of 1538.19 nm, compliant with ITU-T G.694.2 channel spacing.
This transceiver supports up to 40 km of reach over single-mode fiber (SMF, ITU-T G.652).
Yes, it is fully interoperable with Cisco SFP+ interfaces and supports Cisco’s digital optical monitoring (DOM).
It supports a data rate of 10.3125 Gbps in accordance with the 10GBase-DWDM standard.
Yes, the module is hot-pluggable, allowing insertion or removal without powering down the host system.
It requires single-mode fiber (SMF, ITU-T G.652) for optimal signal transmission up to 40 km.
The module operates over a standard commercial range of 0 °C to 70 °C.
Insert the SFP+ transceiver into your switch or router’s SFP+ slot until it clicks, then attach the SMF patch cables.
Yes, it includes DOM functionality for real-time monitoring of optical output power, temperature, and voltage.
It meets IEEE 802.3ae, ITU-T G.694.2, Telcordia GR-20, and RoHS environmental standards.
It is ideal for metro DWDM, long-haul, and data center interconnects at 10 Gbps over single-mode fiber.
DWDM uses narrower channel spacing (0.8 nm) and supports higher channel counts than CWDM for dense wavelength multiplexing.
Yes, it is vendor-neutral and interoperable with any DWDM-compliant SFP+ slot supporting 10GBase-DWDM.
By enabling multiple DWDM channels on a single fiber, it maximizes capacity and reduces overall cabling costs.
