Key Features of LINK-PP LS-BL553101-10I 155M SFP
LINK-PP LS-BL553101-10I is a rugged, industrial-grade BiDi SFP transceiver engineered to provide reliable 155Mbps data links over single-mode fiber up to 10km. This single-fiber module integrates a dual-wavelength optical system, a simplex LC interface, and intelligent digital diagnostics to ensure stable operation in harsh environments. It combines space-saving hardware design with comprehensive real-time monitoring capabilities for critical infrastructure.
LINK-PP LS-BL553101-10I 155M SFP Optical Module
This module utilizes a highly stable 1550nm FP laser as the optical transmitter paired with a sensitive PIN photo detector for the receiver. This optimized component pairing guarantees consistent signal integrity and accurate light detection across wide temperature swings. The robust hardware architecture provides an efficient optical budget required for dependable long-term field operations.
LS-BL553101-10I: 155 Mbps Connectivity for Legacy Telecom
Operating at a stable fast data rate of 155Mbps, this transceiver is fully tailored for SONET OC-3 and Fast Ethernet architectures. It brings modern physical reliability to legacy telecommunications, metro access nodes, and utility networks that rely on these standard transport speeds. The module helps operators sustain older, critical communications equipment without sacrificing link stability.
LS-BL553101-10I Module with 1550nm-TX/1310nm-RX Wavelength
This single-fiber bidirectional (BiDi) transceiver operates on a 1550nm-TX and 1310nm-RX wavelength split to achieve full-duplex communication over a single strand of fiber. This design doubles cabling capacity by eliminating the need for separate transmit and receive fibers. To establish a functional link, it must be deployed alongside a complementary counter-part module that transmits at 1310nm and receives at 1550nm.
Designed for extended spans, the module easily covers paths up to 10km on single-mode fiber without suffering from severe signal degradation. It is built with an industrial temperature tolerance of -40°C to +85°C to protect transmission quality from outdoor weather variations. This makes it an ideal option for connecting distant roadside cabinets, substations, or remote industrial edge nodes.
LS-BL553101-10I Module with Simplex LC Interface
Featuring a compact simplex LC connector, the module minimizes physical space requirements on high-density line cards and switches. The single-port design simplifies cable routing, reduces patch cord clutter, and lowers installation errors during field deployment. This streamlined fiber connection mechanism ensures strong physical retention and low insertion loss.
LS-BL553101-10I Module with DOM for Real-Time Monitoring
The integrated Digital Optical Monitoring (DOM) gives network technicians real-time visibility into internal operational data. It tracks vital diagnostics such as transceiver temperature, laser bias current, supply voltage, and received optical power levels. These metrics allow operators to actively troubleshoot fiber issues and catch link degradation before an actual outage occurs.

Perfect for stretching physical fiber runs on our remote links! We were completely out of spare dark fiber cores on our legacy campus network runs. Switching over to these simplex LC BiDi SFP modules allowed us to squeeze double the capacity out of our existing layout. The link came up instantly and has been dead quiet on errors ever since.

We benchmarked a batch of these industrial-grade BiDi SFP transceivers in our staging lab before deploying them across an 8.5km single-mode span. Using our optical power meter, we verified a very clean transmit level and exceptional receiver sensitivity, leaving a healthy safety margin for a 155Mbps connection. The integrated DOM micro-controller reports highly accurate real-time metrics for voltage, temperature, and laser bias, which we pull seamlessly via SNMP to our central monitoring system. The physical installation has been running continuously through extreme seasonal shifts without a single frame drop, proving the hardware is built to last.

We integrate outdoor perimeter security networks, and roadside cabinets in our region regularly exceed 75°C during peak summer months. Standard commercial transceivers tend to drift and lose signal under these conditions, but these industrial-wide temperature SFP modules haven't dropped a packet. The 155Mbps throughput is incredibly consistent, ensuring our high-definition video backhaul streams smoothly over a 7km single-mode run with zero jitter. The rugged construction and thermal resilience of this hardware make it our primary go-to module for outdoor field layouts.

Flawless operation, but the delivery window slipped by two days. We purchased these for an urgent telemetry network fix, but the package arrived slightly past the estimated delivery date. The modules themselves synced up immediately and have been running error-free ever since, but make sure to order well in advance if you are on a tight schedule.

High-reliability modules for our roadside traffic control systems! We needed a steady 155M SFP optical transceiver for our localized traffic monitoring hubs. The unshielded enclosures get unbelievably hot during summer afternoons, but the industrial wide-temp design of these units handles the heat perfectly. Not a single link flap has been reported so far.
