Arista QSFP-100G-LR4 (XVR-10068-21) 100G QSFP28 LR4 Single-Mode Optical Transceiver Module (1310nm, Duplex LC, 10km DDM)

Basic Parameter Table

Core Product Features

1. Arista original 100GBASE-LR4 CWDM single-mode QSFP28 module, native plug-and-play compatible with all Arista 100G leaf-spine core switches without firmware alarms.
2. Four-channel CWDM 1310nm DFB laser architecture, multiplexes four independent 25G wavelengths onto one duplex single-mode fiber to deliver total 100G bandwidth.
3. Standard duplex LC dual fiber interface, uses low-cost common LC single-mode jumpers instead of expensive MTP ribbon trunk cables, reduces cabling investment for long-distance links.
4. Stable 10km long-reach transmission over OS2 single-mode fiber, standard specification for intra-data center cross-pod and campus inter-building backbone.
5. Full DDM real-time optical monitoring: remotely query each lane TX/RX optical power, module internal temperature and supply voltage for unified core network O&M.
6. Compact hot-swappable QSFP28 packaging, supports online plug/unplug without powering off the switch.
7. Mainstream long-reach 100G single-mode uplink solution for large cloud data center core backbone, multi-building campus network interconnection and metro short-distance optical transport.

Application Scenarios

• Large cloud leaf-spine data center pod-to-pod 10km 100G core backbone interconnection
• Multi-building enterprise / government campus inter-building 100G fiber trunk
• Metro short-distance 100G optical transport access node interconnection
• Core data center reconstruction requiring long-distance single-mode 100G uplinks
