Key Features of LINK-PP LS-BL553101-15C 155M SFP
LINK-PP LS-BL553101-15C is a commercial-grade 155M SFP BiDi single-mode optical transceiver designed for efficient, single-strand fiber communications. It combines a 1550nm-TX/1310nm-RX wavelength split, a 15km operating range, and integrated digital diagnostics to optimize mid-reach enterprise networks. This simplex LC module delivers dependable Fast Ethernet data rates while halving physical cabling requirements.
LINK-PP LS-BL553101-15C 155M SFP Optical Module
The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA), and an MCU control unit. These core components work together to ensure precise electro-optical signal conversion and steady module management. The entire architecture is housed in a standard, hot-pluggable SFP form factor for easy field deployment.
LS-BL553101-15C: 155 Mbps Connectivity for Enterprise LAN Infrastructure
This module delivers a stable 155 Mbps data rate, making it perfect for standard Fast Ethernet applications within corporate local area networks. It provides the exact bandwidth required for legacy systems, device management ports, and dedicated access layer switches. This steady line rate helps maintain predictable throughput across your business network backbone.
LS-BL553101-15C Module with 1550nm-TX/1310nm-RX Wavelength
By utilizing a BiDi design, this transceiver transmits data at 1550nm and receives data at 1310nm simultaneously over a single optical fiber. This dual-wavelength separation prevents signal interference and eliminates the need for a separate pair of fibers. It allows network engineers to double their data capacity on existing single-mode fiber runs.
Engineered for intermediate-reach applications, this optical module easily maintains link integrity over single-mode fiber distances up to 15km. It is an ideal fit for connecting cross-campus buildings, regional distribution hubs, or metropolitan edge locations. The optical power budget is carefully tuned to overcome standard fiber attenuation over these distances.
LS-BL553101-15C Module with Simplex LC Interface
Featuring a compact simplex LC connector, the module establishes a secure and reliable physical connection using only one fiber strand. This single-port design significantly reduces patch cord clutter inside high-density distribution frames and network cabinets. It simplifies fiber routing while cutting down on overall installation and hardware procurement costs.
LS-BL553101-15C Module with DOM for Real-Time Monitoring
Integrated Digital Optical Monitoring (DOM) gives network administrators real-time access to critical operating parameters. You can easily track internal temperature, supply voltage, laser bias current, and both transmitted and received optical power levels. This proactive monitoring capability helps detect potential link issues before they cause network downtime.

Our deployment required a 155M SFP BiDi module capable of reliable 15km single-mode fiber transmission to link up outlying utility monitoring stations. The combination of 1550nm transmission and 1310nm reception over a simplex LC setup works perfectly. We are using standard single-mode patch cords, and the link budget came in exactly at -12dBm, well above the receiver sensitivity floor. The real benefit here is the built-in DOM/DDM module, allowing our NOC team to troubleshoot attenuation changes caused by seasonal fiber sag without dispatching field technicians. This has significantly reduced our operational overhead. Thumbs up!

When you are running low on fiber infrastructure cores in a packed municipal conduit, bidi modules are a literal lifesaver. These 155M SFP 15km units allowed us to spin up 4 new separate logical channels over our remaining 4 dark fiber single strands. The LINK-PP build quality is top tier; the gold finger contacts are thick and clean, and the optical sub-assemblies (OSA) provide excellent isolation between the TX 1550nm and RX 1310nm channels. DOM reporting is fully active on our switches. If you're looking to optimize your fiber network utilization, these are the exact transceivers you need.

Our engineering team was searching for a reliable, cost-effective replacement for legacy SONET OC-3 access nodes. We sampled the LINK-PP 155M BiDi SFP (15km, Simplex LC) and ran it through our rigorous physical layer testing suite. Using an optical spectrum analyzer, the 1550nm transmitter showed a very narrow linewidth with excellent side-mode suppression ratio (SMSR). The receiver threshold at 1310nm handles the attenuation profile comfortably with about 4dB of power margin to spare. DDM/DOM parameters matched our external testing meters within standard tolerances. Excellent build quality, zero compatibility errors on Juniper and Alcatel platforms.

Great modules, shipping took slightly longer. Solid 155M BiDi SFP performance over our 12km single-mode fiber links. The only minor downside is that the shipping took three days longer than our original estimated warehouse turnaround window. Once arrived, they worked out of the box with zero compatibility issues on our routers. Just order ahead of time if you have tight deadlines!

We deployed 10 pairs of the LINK-PP 15km 155M BiDi SFP transceivers across an extensive single-mode fiber (SMF) network spanning approximately 11.8km. Our primary technical concern was whether the 155M bandwidth would hold continuous stability over a 1550nm-TX and 1310nm-RX single-strand layout without polarization loss. After 3 weeks of live deployment on our switches, the metrics are outstanding. The integrated Digital Optical Monitoring (DOM) provides accurate real-time telemetry on transceiver temperature, supply voltage, and laser bias current. No frame slips or link flaps recorded. For enterprise-level multi-site networking on a budget, these single-mode fiber modules are a definitive win.

The SFP module latch mechanism is slightly stiff upon first insertion into our legacy edge routers, required a bit of extra firm pressure to click in securely. Once seated, the 155M link came up instantly and DOM telemetry is reading correctly. Great long-distance 15km single-mode fiber transceiver.

Great 155Mbps SFP optical transceivers for our campus FTTH expansion. My only tiny complaint is that the part number label on the SFP shell uses a very small font size, making it a bit hard to read inside a dark server rack without a flashlight. Performance-wise, the TX 1550nm / RX 1310nm optical link is completely flawless.

We are currently migrating older multi-mode distribution links to single-mode fiber to extend our reach across a newly built residential zone. These 155M BiDi SFP transceivers (TX1550/RX1310) let us achieve a 15km deployment distance without replacing the single-strand fibers we already laid out. The simplex LC interface clicks nicely with a satisfying mechanical engagement. Having DDM/DOM standard diagnostics on such affordable modules makes long-term SLA monitoring much easier for our small engineering team. No compatibility blockages found on our routers. Excellent work by LINK-PP.
