Features

WFL67220FF-QCS

WFL67220FF-QCS product is designed for OLT module based on XGSPON technology. The XGSPON OLT SFP+ product is an integrated module containing a micro-optic component and semiconductor material. The module could implement DDM function. It could be used at key locations in optical networks.

1. Single fiber bi-directional data links with downstream 9.953Gbps and9.953Gbps/2.488Gbps(compatible) upstream

The transceiver supports single-fiber bidirectional transmission, delivering 9.953Gbps downstream and upstream rates for full symmetrical 10G performance. The XGSPON OLT SFP+ product is also backward compatible with 2.488Gbps upstream, allowing it to operate seamlessly in XG-PON (asymmetric) deployments. This dual-mode upstream capability ensures a cost-effective transition from legacy PON systems to next-generation XGS-PON networks.

2. Hot-pluggable capability

The XGSPON OLT SFP+ transceiver supports hot-pluggable operation, allowing it to be inserted into or removed from an SFP+ cage without powering down the host OLT system. This capability eliminates network downtime during module installation, replacement, or upgrade procedures, ensuring uninterrupted service for end users.

3. Support 20km transmission distance with SMF

The XGSPON OLT SFP+ module delivers reliable 20km transmission over single-mode fiber (SMF), covering the vast majority of access network distances. This ensures consistent signal integrity and stable performance across the entire optical budget without requiring additional amplification.

4. Low EMI and excellent ESD protection

The module features low EMI design, reducing electromagnetic noise to maintain signal integrity in high-density network equipment. It also provides excellent ESD protection, guarding sensitive internal components against electrostatic damage during handling and operation. These protections translate into fewer field failures and lower maintenance costs over the product's lifecycle.
