Description

SSN3SLQ4 overview

The SLQ4 is a line board. The SLQ4 can be used on the OptiX OSN equipment series to transmit and receive STM-4 optical signals. The SLQ4 converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SLQ4 converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.

The SLQ4 is available in two functional versions, namely, N1 and N2. The difference between the two versions is with regard to whether they support the TCM function and AU-3 services. The N1SLQ4 is no longer manufactured.

Item	Description
Functional versions	The SLQ4 is available in two functional versions, namely, N1 and N2.
Differences	Specifications of optical modules: single-fiber bidirectional optical modules. Service processing: AU-3 service processing. Maintenance features: loopbacks on VC-4 paths and TCM function.
Substitution	Through the board version replacement function, the N3SLQ41 can substitute for the N1SLQ4 and N2SLQ4 at the same line rate.

Relationship between the feature code of the SLQ4 and the type of optical interface

Board	Feature Code	Type of Optical Interface
SSN1SLQ410 and SSN2SLQ410	10	S-4.1
SSN1SLQ411 and SSN2SLQ411	11	L-4.1
SSN1SLQ412 and SSN2SLQ412	12	L-4.2
SSN1SLQ413 and SSN2SLQ413	13	Ve-4.2
SSN1SLQ414 and SSN2SLQ414	14	I-4

Specifications of the ports of the SLQ4

Port type	Description
I-4	2 km STM-4 two-fiber bidrectional optical interfaces
S-4.1	15 km STM-4 two-fiber bidrectional optical interfaces
L-4.1	40 km STM-4 two-fiber bidrectional optical interfaces
L-4.2	80 km STM-4 two-fiber bidrectional optical interfaces
Ve-4.2	100 km STM-4 two-fiber bidrectional optical interfaces

Item	SSN3SLQ4
Basic functions	Transmits and receives 4xSTM-4 optical signals.
Specifications of the optical interface	Supports different types of standard optical interfaces, namely, the I-4, S-4.1, L-4.1, L-4.2, and Ve-4.2. The characteristics of the optical interfaces of the I-4, S-4.1, L-4.1, and L-4.2 types comply with ITU-T G.957. The characteristics of the optical interface of the Ve-4.2 type comply with the standards defined by Huawei.
Specifications of the optical module	Supports the detection and query of the information about the optical module. Provides the ALS function. The optical interface supports the setting of the on/off state of a laser. Supports the usage and monitoring of the SFP optical module, which facilitates the maintenance and upgrading of the optical module. The N1SLQ4 supports the single-fiber bidirectional optical module, and the single-fiber bidirectional optical module does not support loopbacks at the optical interface by using fiber jumpers.
Service processing	Supports the VC-12 services, VC-3 services, VC-4 services, and VC-4-4c concatenation services. The N2SLQ4 supports the AU-3 services.
Overhead processing	Processes the section overheads of the STM-4 signals. Supports the transparent transmission and termination of the path overheads. Supports the setting and query of the J0, J1, and C2 bytes. Supports one to four channels of ECC communication.
Alarms and performance events	Reports various alarms and performance events, which facilitates the management and maintenance of the equipment.
Protection schemes	Supports the Two-fiber ring MSP, Four-fiber ring MSP, Linear MSP, SNCP, SNCTP, and SNCMP. Supports the fiber-shared MSP and SNCP and processes eight sets of K bytes. A single optical interface supports two MSP protection rings, and one SLQ4 supports a maximum of eight MSP protection rings.
Maintenance features	Supports inloops and outloops at optical interfaces. The N1SLQ4 supports inloops on VC-4 paths. Supports warm resets and cold resets. The warm reset does not affect services. Supports the query of the manufacturing information of the board. Supports the in-service loading of the FPGA. Supports the upgrade of the board software without affecting services. The N2SLQ4 supports the TCM function. Supports the press-to-collect function in fault data collection.
