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.
