## Summary description

BlueOptics BO28L13640DIN is a QSFP28 100GBASE-ER4 optical transceiver designed for 100 Gbps Ethernet links over single-mode fiber up to 40 km. It provides 100G connectivity using ER4 standard, suitable for long-reach metro and data center interconnects. Use cases include uplinks between switches, aggregation links and WAN connections where reliable 100G long-distance transmission is required.

## Long description

BlueOptics BO28L13640DIN is a QSFP28 optical transceiver that implements the 100GBASE-ER4 standard for 100 Gbps Ethernet over single-mode fiber. The module supports long-reach links up to 40 km, making it suitable for metro, inter-data-center and WAN interconnects that require reliable high-speed connectivity. The compact QSFP28 form factor enables four-lane 25 Gbps electrical interfaces aggregated to deliver 100 Gbps optical throughput, compatible with systems that accept QSFP28 100G modules.
Advantages
The transceiver offers long-reach single-mode performance up to 40 km with ER4-compliant optics, enabling efficient 100 Gbps links without the need for regeneration. The QSFP28 form factor provides a high port density and hot-pluggable operation for easy installation and maintenance. The module is engineered for industry-standard electrical and optical interfaces, supporting interoperability with a wide range of switches and routers that accept QSFP28 optical modules.
Suitable for
Metro and regional links requiring 100 Gbps over single-mode fiber
Data center interconnects (DCI) between sites up to 40 km apart
Aggregation and uplink connections between switches and routers
WAN links and service provider backbone segments
Key specifications
Optical standard: 100GBASE-ER4 for long-reach 100 Gbps Ethernet
Form factor: QSFP28, hot-pluggable
Maximum link distance: up to 40 km over single-mode fiber
Wavelength/multiplexing: ER4 four-lane optical architecture
Data rate: 100 Gbps aggregated (4 × 25 Gbps lanes)

Typical applications: metro, DCI, aggregation, WAN
How to use
Install the QSFP28 transceiver into a compatible QSFP28 port on the switch, router or transponder while the host port is powered and follow the equipment vendor’s hot-plug handling procedures. Connect single-mode optical fiber using appropriate LC or MPO/MTP patching infrastructure as required by the system design and ensure correct lane alignment and polarity. After insertion, verify the link status and error counters through the host system’s management interface and monitor optical power and signal metrics to confirm proper operation.
Usage recommendations
For reliable long-reach operation, use low-attenuation single-mode fiber and maintain clean connector endfaces. Verify compatibility with the host equipment for QSFP28 100GBASE-ER4 modules and confirm that optical budgets and link loss (including patch panels and splices) remain within the module’s operational limits for distances up to 40 km.
