The Atop Technology CWDM SFP transceiver is a hot-pluggable optical module designed for 1.25 Gbps data rates across CWDM wavelengths from 1270 nm to 1610 nm. It supports transmission distances up to 80 km using single-mode fiber and complies with SFP MSA and IEEE 802.3z standards. The module features a DFB laser transmitter and PIN photodiode receiver, with digital diagnostics via I2C interface. No internal cooling or active components beyond the transceiver chip are indicated.

The product operates within a commercial temperature range of 0°C to 70°C. Power consumption is typical for 1.25 Gbps SFPs at under 1 W. The form factor conforms to SFP specifications, ensuring compatibility with Cisco, Juniper, Huawei, and other vendor equipment. Wavelengths are fixed per unit, with standard grids including 1270, 1290, 1310, 1330, 1350, 1370, 1390, 1410, 1430, 1450, 1470, 1490, 1510, 1530, 1550, 1570, 1590, and 1610 nm. No multi-wavelength tunability is supported.

This module is used in enterprise networks, telecom aggregation layers, and data center interconnects requiring cost-effective, long-reach links. Buyers include network equipment integrators, system builders, and service providers replacing legacy optics. Packaging is anti-static with individual barcode labeling.
