## Summary description

Compatible BlueOptics QSFP transceiver (model 78P6916-BO / BO25K859S2D) provides 40GBASE-SR4 short‑reach connectivity over multimode fiber using an MPO/MTP interface. It uses 4×850 nm wavelengths, supports links up to 150 m and operates in the 0–70°C range. Suitable for data center aggregation, switch-to-switch links and high‑speed server uplinks.

## Long description

The BlueOptics QSFP Transceiver 78P6916-BO (BO25K859S2D) provides 40GBASE-SR4 short‑reach connectivity over multimode fiber using an MPO/MTP interface. Designed for 40 Gbit/s links, it transmits over four parallel lanes at 850 nm and supports distances up to 150 meters on suitable multimode fiber. The module operates in temperature ranges typical for data centre and enterprise networking equipment and fits QSFP form‑factor ports for aggregation switches, routers and server NICs.
Advantages
This BlueOptics QSFP transceiver offers standardized 40GBASE-SR4 performance in a QSFP package with an MPO/MTP connector for simple parallel multimode links. It supports up to 150 m on recommended multimode fibers, enabling short‑reach connections in racks and across data hall aisles. The module is suitable for hot‑swap operation in compatible QSFP cages and is specified to operate across a 0–70°C ambient temperature range to match typical equipment environments.
Suitable for
 40G switch-to-switch uplinks in data centres and enterprise networks
 High-speed server uplinks and top-of-rack aggregation
 Parallel multimode fiber links using MPO/MTP trunk cables
 Short-reach connections within campus buildings and equipment rooms
When it may not be suitable
This transceiver is optimized for short‑reach multimode applications and is not intended for singlemode long‑reach links or distances beyond the specified 150 m. It requires equipment with a QSFP port and MPO/MTP cabling; it will not operate with simple duplex LC singlemode connectors or without compatible MPO/MTP trunk fibres and polarity management. Environments requiring extended temperature ranges or industrial ratings beyond 0–70°C should consider modules specified for wider operating conditions.
Key specifications
 Data rate: 40 Gbit/s (40GBASE-SR4)
 Optical lanes: 4 × 850 nm
 Medium: Multimode fiber (MPO/MTP interface)
 Maximum link distance: up to 150 m (on appropriate multimode fiber)
 Form factor: QSFP (Quad Small Form-factor Pluggable)
 Operating temperature range: 0–70°C
How to use
Install the QSFP transceiver into a compatible QSFP port following the host equipment’s hot‑swap and ESD guidelines. Connect an MPO/MTP multimode trunk cable between matching MPO/MTP ports, ensuring correct polarity and that the fiber type and modal bandwidth support 40GBASE‑SR4 at the targeted distance. Verify link status and diagnostics through the switch or host interface after insertion. If necessary, use appropriate MPO/MTP fanouts or breakout cables to connect to devices with multiple LC ports, observing manufacturer guidance for pinout and polarity.
What to consider before purchase
 Confirm host device compatibility with QSFP 40GBASE‑SR4 modules and MPO/MTP connectivity
 Verify multimode fiber type (OM3/OM4) and channel budget to achieve required reach up to 150 m
 Ensure cabling polarity and MPO/MTP pinout match the network design or use verified fanout cables
 Check operating temperature requirements of the deployment environment against the 0–70°C range
Usage recommendations
Use OM3 or OM4 multimode trunk cables and maintain proper MPO/MTP connector cleaning and handling. Test links after installation and monitor diagnostics via the host to ensure stable 40G operation within the specified distance and temperature limits.
