JDSU FST Series Test Modules

2 models with full specifications from JDSU.

The JDSU Field Services Tester (FST) family offers modular, field-ready test solutions designed for network installation, turn-up, and maintenance. Built to interface with the JDSU FST-2000 TestPad platform, these modules target distinct transmission technologies. The FST-2310 provides deep SONET/SDH test capabilities ranging from DS1/E1 up to OC-48/STM-16 rates. Meanwhile, the FST-2802 serves as a dual-port Gigabit Ethernet test set designed for copper and optical Ethernet verification. Technicians can swap modules depending on the specific physical layer and protocol requirements of the circuit under test.

SONET and SDH Testing with the FST-2310

The JDSU FST-2310 is a specialized SONET/SDH test module. It handles troubleshooting and circuit verification from DS1/E1 up to OC-48/STM-16 rates, including support for STS-1, OC-3, and OC-12. Depending on the chosen configuration, it operates over 1310 nm or 1550 nm wavelengths. For structural transmission testing, the module performs Bit Error Rate Testing (BERT), alarm generation and detection, and error injection. Additionally, it offers deep optical layer troubleshooting via pointer generation and analysis alongside overhead manipulation.

Ethernet Service Verification with the FST-2802

The JDSU FST-2802 is a dual-port Gigabit Ethernet test set. It allows technicians to perform full wire-speed traffic generation and analysis up to 1 Gbps line rates. Equipped with two 10/100/1000Base-T RJ-45 copper ports and two 1000Base-X SFP optical transceiver slots, it accommodates both physical media types in the field. The unit supports Ethernet, IP, and TCP/UDP traffic generation. For standard SLA verification, it features a built-in RFC 2544 test suite that measures throughput, latency, frame loss, and back-to-back frames.

Shared Platform Architecture

Both the FST-2310 and FST-2802 are compatible with the JDSU FST-2000 TestPad mainframe. This modular approach allows field engineers to leverage a single base platform while swapping application-specific modules as service requirements change from legacy optical transport networks to modern packet-switched Ethernet backhaul.
