LINK-PP LS-BL315501-40C serves as a specialized small form-factor pluggable transceiver designed to optimize single-strand fiber infrastructure. This bi-directional hardware unites a streamlined physical port configuration with extended optical reach to support legacy and access network layouts. Its architecture brings together precise optoelectronic parts and diagnostic functions to secure stable link operation.
The internal layout incorporates an FP laser transmitter alongside a PIN photo detector receiver for dependable lightwave conversion. This specific hardware pairing maintains clean waveform patterns and handles light sensitivity efficiently across the single-mode glass. It ensures the physical layer remains robust and free from unexpected signal degradation.
Operating at a steady data rate of 155Mbps, this module is perfect for Fast Ethernet backhauls and legacy telecom infrastructure. It provides a dependable connection for edge routing devices and regional network nodes that require fixed-rate data streams. The standardized signaling rate allows for smooth integration into existing enterprise platforms.
This transceiver uses a 1310nm-TX and 1550nm-RX wavelength pair to separate transmitting and receiving pathways over a single fiber strand. This bi-directional frequency separation eliminates interference and optimizes spectrum efficiency. It allows network operators to double their bandwidth capacity without laying new fiber.
Designed for extended link budgets, this hardware easily bridges distances up to 40km without requiring inline optical amplifiers. It overcomes standard path attenuation, making it ideal for metropolitan access networks and cross-town connections. The strong optical power budget ensures consistent link availability over long single-mode runs.
Utilizing a single-port simplex LC receptacle, the unit establishes a tight, low-loss connection with standard fiber connectors. This mechanical interface reduces the patch cable footprint inside crowded termination cabinets and patch panels. It streamlines hardware deployment by cutting the required physical fiber terminations in half.
The integrated Digital Diagnostic Monitoring framework provides host switches with live telemetry data directly from the optical link. Operators can instantly pull tracking metrics for operational voltage, internal module temperature, and RX/TX power levels. This telemetry simplifies link diagnostics and prevents sudden network downtime through early indicator warnings.

Q: Can this BiDi module establish a link over a single strand of legacy 62.5µm OM1 multi-mode fiber for short distances? By P***n on 2026-04-05
A: No, the 1310nm/1550nm laser configurations are precisely tuned for 9/125µm single-mode fiber optics and will suffer extreme modal dispersion on multi-mode glass. By admin on 2026-04-06
Q: Is this module sealed well enough to survive high-humidity server room conditions? By N***n on 2026-02-26
A: Yes, the physical chassis handles non-condensing relative humidity levels from 5% up to 85% without experiencing optical degradation. By admin on 2026-02-27
Q: Can the DDM telemetry warn us about a dirty fiber patch cord before the link completely drops? By L***m on 2026-01-20
A: Yes, by tracking real-time drops in the RX optical power metric, your team can proactively schedule maintenance before packet loss occurs. By admin on 2026-01-21
Q: Can this Fast Ethernet 155M SFP handle legacy telecom protocols like SONET OC-3? By O***y on 2025-12-17
A: Yes, the internal optical engine natively supports both 155Mbps Fast Ethernet data streams and synchronous telecom transport architectures. By admin on 2025-12-18
Q: Does continuous DDM polling impact the data transmission performance or latency of the 155Mbps link? By M***d on 2025-06-18
A: Not at all. The diagnostic circuitry operates entirely on an independent internal management bus, completely isolated from the primary data path. By admin on 2025-06-19
