The DIGISOL DG-SA1136-BDR and DIGISOL DG-SA1136-BDT are high-performance long-range optical transceiver modules designed for Gigabit fiber networking over a single-mode single fiber connection.
Product Overview
These SFP modules support:
- data transfer rates up to 1.25Gbps
- transmission distance up to 80km
- communication over 9/125µm single-mode fiber (SMF)
They are ideal for:
- telecom networks,
- ISP infrastructure,
- enterprise backbone connectivity,
- industrial fiber applications.
Key Features
High-Speed Optical Connectivity
Supports:
- up to 1.25Gbps data links
Suitable for:
- Gigabit Ethernet,
- Fiber Channel,
- high-speed uplink applications.
Long Distance Transmission
Designed for:
- up to 80km fiber transmission
- over single-mode fiber (SMF)
Excellent for:
- metro networks,
- campus interconnects,
- long-distance surveillance systems.
Single Fiber BiDi Technology
These are Bi-Directional (BiDi) SFP modules.
Instead of using:
- one fiber for TX
- one fiber for RX
they use:
- a single optical fiber strand
- different wavelengths for transmit and receive.
Benefits:
- reduces fiber deployment cost,
- saves fiber resources,
- simplifies infrastructure expansion.
DFB Laser Transmitter
Uses a Distributed Feedback (DFB) laser for:
- stable optical output,
- high transmission quality,
- superior long-distance performance.
PIN Photo Detector
Ensures reliable optical signal reception with good sensitivity.
Digital Diagnostic Monitoring (DDM/DDMI)
Supports real-time monitoring of:
- module temperature,
- supply voltage,
- TX optical power,
- RX optical power,
- laser bias current.
Helpful for:
- network diagnostics,
- preventive maintenance,
- troubleshooting.
LC/UPC Optical Interface
- Standard BiDi LC connector
- Easy integration into existing fiber environments.
Hot Pluggable
Modules can be inserted or removed:
- without shutting down the networking equipment.
Environmental Compliance
- RoHS compliant
- Lead-free construction
Pairing Requirement
These modules work as a complementary pair:
| Module | Role |
|---|---|
| DG-SA1136-BDT | One wavelength direction |
| DG-SA1136-BDR | Opposite wavelength direction |
One device uses the BDT module, and the remote side uses the BDR module.
Typical Applications
- ISP fiber backbone
- Enterprise campus networking
- Telecom infrastructure
- Long-distance CCTV fiber links
- Smart city deployments
- Industrial Ethernet
Compatible Equipment
Compatible with many SFP-enabled switches and routers from:
- DIGISOL
- Cisco
- MikroTik
- Juniper
- Ubiquiti
- TP-Link
