HUAWEI OSN902 (OSN902 for short) is a WDM transmission platform customized based on Data Center Interconnect (DCI) requirements and mainly applies to DCI scenarios.
OSN902 supports access of 10GE/40GE/100GE services and a maximum single-wavelength capacity of 200 Gbit/s.
OSN902 provides multiple open interfaces. DCI users can perform secondary development to integrate this product's management into data center management systems.

Table 1 Functions and features of the HUAWEI M201 board (Line Mode)

Function and Feature Description
Basic function Mutual conversion between 10GE/40GE/100GE signals and OTU4/OTUC2 signals
Client-side service type
  • 10GE LAN: Ethernet service at the rate of 10.31 Gbit/s
  • 40GE: Ethernet service at the rate of 41.25 Gbit/s
  • 100GE: Ethernet service at the rate of 103.125 Gbit/s
OTN function
  • Provides OTU4/OTUC2 ports on the WDM side.
  • Uses the frame formats and overhead processing methods defined in ITU-T G.709.
  • Supports the PM function at the ODUk (k = 2e, 3, 4, or C2) layer.
  • Supports the SM function at the OTUk (k = 4 or C2) layer.
WDM specifications Supports ITU-T G.694.1-compliant DWDM specifications.
Tunable wavelength function Supports tuning of the optical signals output on the WDM side within the range of 80 wavelengths in C-band at a 50 GHz channel spacing.
ESC Supported
PRBS
  • Supported when the client service type is 10GE/40GE
  • Supported in the WDM side
LPT Supported only when the client-side service type is 10GE
Error correction coding
  • RS-FEC coding is supported when the client-side service type is 100GE.
  • SDFEC2 coding is supported when the WDM-side port works in 100G_QPSK mode.
  • SDFEC coding is supported when the WDM-side port works in 200G_16QAM mode.
    NOTE:

    RS-FEC is enabled for 100GBASE-SR4 optical modules and disabled for other modules by default.

Performance and alarm monitoring
  • Monitors BIP8 bytes (burst mode) to help locate line faults.
  • Monitors OTN alarms and performance events.
  • Monitors parameters such as the bias current, operating temperature, and optical power of a laser.
  • Supports the Ethernet RMON function.
Regeneration board M201
ALS Supported on the client side
Test frame Supported only when the client-side service type is 100GE
Delay measurement (DM) Supported
Protection scheme
  • Client 1+1 protection
  • Intra-board 1+1 protection
  • Optical line protection
Ethernet service encapsulation mode
  • 10GE LAN: bit transparent mapping (11.1G)
  • 40GE: GE(TTT-GMP)
  • 100GE: 100GE(GMP)
Loopback
  • WDM-side and client-side loopback:
    • Inloop and outloop are supported on both the WDM and client sides.
    • The client-side loopback is not supported when 10GE services are received on the client side.
  • Channel loopback:
    • Inloop and outloop are supported on both the WDM and client sides.
    • Client-side channel loopback: It is supported only when 10GE services are received on the client side.
    • WDM-side channel loopback: The ODU4 channel loopback is supported only when 10GE/40GE services are received and the 200G_16QAM mode is used on the WDM side.
