100G Bypass Protection Device Product Features

  • Pluggable modular design, all components support hot swapping

  • Single device supports 4 pairs of 100G link access Bypass capability

  • TAP interface with splitter function to provide link data mirroring

  • With optical power amplification protection function, provide the original link optical power amplification at the same time can be amplified link Bypass protection

  • Supports three switching/protection modes:

  • K0 hard pass-through, K1 soft forwarding and mirroring, and K2 soft forwarding and serial connection.

  • Hard switching time<5ms, soft switching supports no packet loss on external links

  • Soft forwarding state supports high-speed non-blocking full wire-speed processing capability

  • Supports panel physical switches to toggle link state

  • Supports link hold mode, which maintains the set state regardless of changes in the link state

  • Supports service module heartbeat monitoring function

  • Supports port optical power monitoring, packet statistics

  • With ACL rule matching function, support for the winning traffic forwarding or passthrough

  • Dual power supply redundant backup design, power modules can be hot-swappable, support for AC 90~260V, DC -36 ~ -72V power supply options

  • Dual-fan redundant backup design with hot-swappable fan modules

  • With CLI, SNMP and other management functions, support open API interface management.

100G Bypass Protection Device Product Specifications

Indicator name


Number of 100G link accesses

4 pairs

100G Link optical module standard


Link interface

Standard mode WAN interface

8 pairs of LC interfaces (every 2 pairs access 1 external bidirectional link)

Low light mode WAN interface

8 pairs of LC interfaces (every 2 pairs access 1 external bidirectional link)

TAP interface

4 pairs of LC interfaces (each pair outputs 1 external bidirectional link mirroring optical signal)

LAN interface

8 QSFP28 100G optical interfaces (1 pair of local bi-directional links in series of 2)

Link protection mode

K0 mode

Hard passthrough mode, in which the physical link to the WAN interface is passthrough through a physical switching device;

K1 mode

Soft forwarding and mirroring mode, that is, through the control chip to the WAN interface between the packet corresponds to forwarding to achieve straight-through

K2 mode

Soft forwarding and concatenation mode, i.e., packets are concatenated and forwarded between the WAN and LAN interfaces via the control chip
