The CWDM-SFPGE-1491 is a CWDM eSFP optical transceiver module supporting 2.5 Gbps over single-mode fiber at 1491 nm, designed for links up to 80 km with LC connectors.
This module is ideal for metro, access, and long-haul transport networks, CWDM systems, enterprise backbone links, and high-speed data center interconnects.
It supports a maximum unregenerated link distance of 80 km over single-mode fiber (SMF) with an optical budget suitable for long-haul CWDM deployments.
The module is optimized for ITU-T G.652 single-mode fiber, delivering low-loss transmission over distances up to 80 km.
It uses duplex LC connectors for reliable, low-insertion-loss connections in compact form factors.
The transceiver operates at a fixed 1491 nm CWDM wavelength, ensuring channel isolation and compatibility with CWDM MUX/DEMUX.
It supports 2.5 Gbps (Gigabit Ethernet) data rates, fully compliant with SFP MSA and IEEE 802.3ah 1000BASE-BX specifications.
This module is built in the industry-standard enhanced small form-factor pluggable (eSFP) package for space-constrained network environments.
Yes, it supports hot-plug capability, allowing insertion and removal without powering down the host device, minimizing downtime.
It is interoperable with Cisco, Juniper, HP, Huawei, Dell, and other SFP-compliant switches and routers that accept third-party transceivers.
Yes, it features Digital Diagnostics Monitoring (DDM) compliant with SFF-8472, providing real-time monitoring of optical power, temperature, and voltage.
The module operates between 0 °C and 70 °C (commercial) with an extended industrial option from –40 °C to 85 °C for harsh environments.
By enabling CWDM multiplexing, it multiplies channel capacity on a single fiber, reducing cabling costs and power consumption per wavelength.
It is CE, FCC, RoHS, and TUV certified, meeting global safety, electromagnetic compatibility, and environmental standards.
The module consumes less than 1 W in typical operation, making it energy-efficient for high-density deployments.
