LINK-PP LS-SM5506-80C Technical Overview

The LINK-PP LS-SM5506-80C is a hot-pluggable 622Mbps Small Form-factor Pluggable (SFP) duplex LC optical transceiver module designed for long-reach telecommunications, SONET OC-12 / SDH STM-4, and sub-gigabit optical links. Operating at a nominal wavelength of 1550nm, it supports long-haul transmission distances up to 80km over single-mode fiber (SMF/G.652). Built with a 1550nm DFB laser transmitter, PIN photodiode receiver with trans-impedance preamplifier (TIA), and full Digital Optical Monitoring (DOM/DDM) support per SFF-8472 specifications, it delivers reliable long-range optical connectivity across legacy telecom and utility networks.

622 Mbps Data Rate & 80km Long-Reach Range: Supports 622 Mbps SONET OC-12 / SDH STM-4 transmission over duplex LC single-mode fiber up to 80km.
1550nm DFB Laser Subsystem: High-performance 1550nm DFB transmitter delivers -3 to +3 dBm optical launch power for extended link budgets.
Digital Optical Monitoring (DOM/DDM): Real-time monitoring of TX/RX optical power, laser bias current, module temperature, and supply voltage per SFF-8472.
MSA & Protocol Compliance: Fully compliant with SFP Multi-Source Agreement (MSA), SFF-8472, Class 1 laser safety, and commercial 0°C to 70°C operating temperature ratings.

Key Design Benefits

80km Long-Haul Transmission: High launch power (-3 to +3 dBm) and -28 dBm receiver sensitivity provide an optical link budget suitable for 80km single-mode fiber links.
Real-Time DOM Diagnostics: Internal digital diagnostics interface (DOM) allows network administrators to monitor live transmit/receive optical power levels and thermal parameters.
Hot-Pluggable SFP Form Factor: Enables module insertion and replacement in active telecom switches, routers, or SDH add-drop multiplexers without powering down the host system.
Multi-Vendor System Interoperability: Engineered to comply with SFP MSA standards for broad compatibility across legacy telecom equipment and enterprise networking cards.
Supply Chain Continuity: Offers network engineering and procurement teams a qualified 622Mbps 1550nm 80km SFP option for ongoing network maintenance and secondary sourcing.

Optical Architecture & Diagnostic Performance

The LS-SM5506-80C incorporates electro-optical subsystems directly within a compact metallic SFP enclosure to ensure signal integrity across long-haul optical channels.

Transmitter & Receiver Subsystems

The transmitter incorporates a 1550nm DFB laser driver supplying -3 to +3 dBm optical output power. The receiver incorporates a PIN photodiode with an integrated trans-impedance preamplifier (TIA) providing -28 dBm receiver sensitivity and a -8 dBm overload threshold across 622Mbps data streams.

Digital Diagnostic Monitoring (DOM)

An SFF-8472 compliant MCU control unit monitors real-time operational parameters over a 2-wire serial interface. Monitored metrics include transmitted optical power, received optical power, laser bias current, module operating temperature, and internal supply voltage.

Mechanical & Interface Specifications

The LS-SM5506-80C is enclosed in a standard metal SFP housing featuring a latching bail mechanism for secure insertion and removal. The optical interface uses an industry-standard Duplex LC/UPC receptacle compatible with single-mode fiber (SMF G.652) patch cables. The module operates within a commercial temperature range of 0°C to 70°C and satisfies Class 1 laser safety requirements.

Target Applications

SONET OC-12 / SDH STM-4 Telecom Links: Long-reach 80km 622 Mbps optical transport in telecommunication core switches and add-drop multiplexers (ADM).
Sub-Gigabit Enterprise & Utility Networks: Extended-distance optical interconnects for power utility communication grids and transport controllers.
Legacy Optical Network Maintenance: Replacement and expansion modules for legacy 622Mbps optical line cards and multi-service provisioning platforms (MSPP).

LINK-PP LS-SM5506-80C Design Verification Checklist

When evaluating the LINK-PP LS-SM5506-80C for optical network expansion or secondary sourcing qualification, network engineers should verify the following parameters against their system specification:

Data Rate & Protocol Matching: Confirm that target line cards support 622 Mbps data rates (SONET OC-12 / SDH STM-4 / Fast Ethernet sub-rate).
Fiber Media & Distance Verification: Confirm single-mode fiber (SMF G.652) cable infrastructure for up to 80km link distance.
Optical Link Budget: Verify that TX power (-3 to +3 dBm) and RX sensitivity (-28 dBm) satisfy system link attenuation requirements without exceeding -8 dBm receiver overload.
Switch SFP Port Compatibility: Confirm that target switch or multiplexer ports support standard SFP modules and SFF-8472 DOM protocols.
