## Summary description

The BlueOptics SFP991-1ELH20-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It operates at a wavelength of 1550 nm and is designed for reliable networking applications. The module features a metal housing, operates at an input voltage of 3.3 V, and weighs only 3 g, making it a lightweight and efficient choice for network setups.

## Long description

The BlueOptics SFP991-1ELH20-BO is a single‑mode fiber SFP transceiver module designed for 1000BASE‑ZX applications. It supports a maximum data transfer rate of 1250 Mbit/s at a wavelength of 1550 nm, features a metal housing and a lightweight design (approx. 3 g). The module uses an SFP interface and an LC duplex optical connector (MSA‑compliant) and is intended for long‑reach optical links on single‑mode fiber.
Advantages
The transceiver offers compatibility with devices that accept standard SFP 1000BASE‑ZX modules and supports Ethernet and related high‑speed protocols at up to 1.25 Gbit/s. A metal housing provides mechanical robustness and thermal conduction, while the compact SFP form factor allows easy hot‑swap installation. The 1550 nm wavelength and single‑mode design enable long‑distance links when used with appropriate fiber and patching. The module also supports common digital diagnostic monitoring functions when the host device provides DDM/DOM access.
Suitable for
Long‑reach single‑mode Ethernet links (1000BASE‑ZX)
Interconnection of switches, routers and storage systems supporting SFP modules
Backbone and metropolitan fiber links requiring 1550 nm optics
Environments where compact, hot‑swappable transceivers are needed
Key specifications
Interface type: SFP (small form‑factor pluggable)
Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
Optical wavelength: 1550 nm
Fiber type: single‑mode fiber (LC duplex connector)
Housing: metal, compact SFP form factor
Supply voltage: 3.3 V
Weight: approximately 3 g
Color: silver
How to use
Install the BlueOptics SFP991-1ELH20-BO by inserting the SFP module into a compatible SFP slot on the host device until it latches. Connect single‑mode LC duplex fiber patch cords to the transmit and receive ports, taking care to match Tx to Rx on the opposing transceiver. Ensure the host device supports 1000BASE‑ZX optics and, if you require remote monitoring, that the device exposes DDM/DOM registers. Observe standard electrostatic discharge precautions and follow the host vendor’s guidelines for hot‑swap and firmware compatibility.
Usage recommendations
For reliable long‑distance performance, use quality single‑mode fiber cabling and LC duplex patch cords, verify link attenuation and connector cleanliness, and confirm that the host equipment firmware supports third‑party SFP modules and DDM/DOM monitoring if required.
