Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

transceiver-db

v1.0.0

Published

Open-source optical transceiver database. 89 products, 39 IEEE/MSA standards, 16 form factors, 9 speed tiers. SFP to 800G OSFP.

Readme

transceiver-db

npm version License: MIT TypeScript Zero Dependencies

Open-source optical transceiver database for network engineers, tooling developers, and infrastructure automation.

159 products. 42 IEEE/MSA standards. 16 form factors. 9 speed tiers.

From 1G SFP to 800G OSFP. Zero dependencies.

Why?

No open-source transceiver database existed. Network engineers, inventory systems, and automation tools had to maintain their own fragmented lists. Now there is a single, typed, searchable source of truth.

Install

npm install transceiver-db

Quick Start

import { searchTransceivers, getBySpeed, getStandard } from 'transceiver-db';

// Search by any keyword
const results = searchTransceivers('100G LR');
console.log(results.map(t => `${t.standard} (${t.formFactor}) - ${t.reachLabel}`));

// Filter by speed
const optics400g = getBySpeed('400G');
console.log(`Found ${optics400g.length} 400G transceivers`);

// Look up an IEEE standard
const standard = getStandard('400GBASE-DR4');
console.log(standard?.notes); // "4x100G parallel SMF. THE key 400G data center optic."

API Reference

Transceivers

import {
  transceivers,          // All 159 transceivers (readonly array)
  searchTransceivers,    // Full-text search across all fields
  getByFormFactor,       // Filter by form factor ("SFP+", "QSFP-DD", etc.)
  getBySpeed,            // Filter by speed tier ("10G", "100G", "400G", etc.)
  getByReach,            // Filter by minimum reach in meters
  getByCategory,         // Filter by category ("DataCenter", "Coherent", etc.)
  getById,               // Get single transceiver by ID
} from 'transceiver-db';

Standards

import {
  standards,             // All 42 IEEE/MSA standards
  getStandard,           // Find by exact or partial name
  searchStandards,       // Search by keyword
} from 'transceiver-db';

Competitors

import {
  competitors,           // 12 major vendors (Cisco, Juniper, Arista, etc.)
  getCompetitor,         // Find by name
} from 'transceiver-db';

Breakout Cables

import { breakouts } from 'transceiver-db'; // 11 breakout configurations

Types

import type {
  Transceiver,
  Standard,
  Competitor,
  Breakout,
  FormFactor,      // "SFP" | "SFP+" | "QSFP-DD" | "OSFP" | ...
  FiberType,       // "MMF" | "SMF" | "Copper" | "N/A"
  ConnectorType,   // "LC" | "MPO-12" | "MPO-16" | "RJ45" | ...
  ProductCategory, // "DataCenter" | "Metro" | "Coherent" | "DAC" | ...
  PriceTier,       // "Budget" | "Standard" | "Premium"

} from 'transceiver-db';

Coverage

| Speed | Products | Form Factors | |-------|----------|-------------| | 1G | 9 | GBIC, SFP | | 10G | 13 | XFP, SFP+ | | 25G | 6 | SFP28 | | 40G | 4 | QSFP+ | | 50G | 2 | SFP56 | | 100G | 20 | QSFP28, CFP, CFP2, CFP4, CXP | | 200G | 4 | QSFP56 | | 400G | 18 | QSFP-DD, OSFP, CFP2-DCO | | 800G | 5 | OSFP | | DAC | 6 | SFP+ to OSFP | | AOC | 3 | SFP+ to QSFP-DD |

Each transceiver includes: standard, form factor, speed, reach, fiber type, wavelengths, connector, power consumption, temperature range, vendor compatibility patterns, use case description, and tags.

Data Sources

All data comes from publicly available sources:

  • IEEE 802.3 standards (802.3z, 802.3ae, 802.3ba, 802.3bs, 802.3cd, 802.3cu, 802.3cm, 802.3df, etc.)
  • OIF standards (400ZR, 800ZR)
  • Multi-Source Agreements (100G CWDM4 MSA, 100G PSM4 MSA, 100G Lambda MSA, OpenZR+)
  • Vendor datasheets and public documentation

Contributing

Contributions welcome. To add a new transceiver:

  1. Fork the repo
  2. Add the entry to src/database.ts following the existing format
  3. Include all required fields from the Transceiver type
  4. Add relevant vendor compatibility patterns
  5. Submit a PR with a description of what you added
