Application
- Smooth upgrade, cost savings: SR-BIDI can be directly plugged into the existing 10G/25G lines without the need to dismantle the old lines and deploy expensive 8-core MPO fiber systems. By using dual-mode LC, it significantly reduces the cost of wiring renovation and enables gradual equipment upgrades at the device end, with high flexibility.
- Suitable for “leaf spine” networks: SR-BIDI modules are commonly used for server uplinks in data centers or interconnection of Leaf switches. It can also be downward compatible and work in conjunction with the 400G SR4.2 BIDI module to achieve a branch connection of 1x400G to 4x100G, protecting future investments.
